Abstract

The microstructure and the hardness due to addition of copper of the Al-Si-Zn-Mg-Cu Alloy have been investigated. The copper has been varied from 0 wt.%– 4.9 wt.% in order to see how the microstructure and the hardness of the alloy change. The Heat treatment at temperature 510 oC during 5 hours and then cooling to ambient temperature, have done to foster the dissolution of copper in the crystal and then precipitate during cooling. The results show that the alloying element form a phase distributed in the matrix of the alloy. Increasing the content of the copper makes the form of the second phase smaller and at the matrix show fine particle distributed mostly entire of the surface. The hardness of the alloy increase as the copper content increase. The increase in hardness might come from the fine particle distributed in the matrix. The onset, endset and melting temperature tend to decrease as the copper content increase.

Abstract

Alloy merupakan material logam campuran yang dibuat untuk menghasilkan sifat mekaniknya, ketahanannya terhadap kondisi lingkungan kerja maupun sifat magnetik yang diharapkan. Material alloy yang dibuat menggunakan Compact Arc Melter MAM–1 memiliki resiko terbuangnya sejumlah bagian (mass loss) komposisi saat peleburan. Untuk itu perlu diidentifikasi pengaruh metode peleburan yang digunakan terhadap  mass loss dan hubungannya dengan Hume-Rothery’s Rules. Dalam penelitian ini telah dibuat sistem alloy Ni20Fe30Mn32Al18 (at. %) menggunakan Compact Arc Melter MAM – 1 dengan variasi level busur. Ditemukan bahwa penggunaan busur api level 3 menghasilkan kehilangan massa yang lebih besar dari level 4. Namun, komposisi paduan yang diperoleh dengan busur api level 3 lebih proporsional terhadap komposisi yang direncanakan dibandingkan dengan busur api level 4, yang mengalami defisit kandungan Mn. Dari Hume-Rothery’s Rules diketahui bahwa perbedaan jari-jari atom dan elektron valensi antara elemen pelarut dan terlarut mempengaruhi besarnya mass loss yang terjadi. Untuk itu, agar rasio komposisi (wt. %) paduan yang dihasilkan proporsional dengan komposisi yang direncanakan, maka busur api yang digunakan dalam peleburan adalah busur api level 3.

Abstract

The Geothermal fluids were disturbed by volcanic gas sulfide deposit reactions which form by reaction of metal(s) with H2S. this sulfate acid is one of the most corrosive compounds in the steam which lead the pitting, stress corrosion cracking and other corrosion mechanisms. An optical microscope, XRF dan X-ray diffraction is used to observe the sediment samples that came from stationary blades. The results show that it mainly consists of 89.7%wt iron sulfide (FeS) and 10.3%wt arsenic trisulfide (As2S3). This phase is toxic by inhalation and ingestion. Downstream steam pipeline treatment is required to reduce sulfide carried away into steam turbines such as scrubbing or washing steam. For this reason, special handling is needed for the toxic waste resulting from washing.

Abstract

Bilah sebagai salah satu komponen yang berfungsi sebagai pelontar bola-bola logam dalam mesin shot blasting, masih banyak yang diimpor dari luar negeri. Namun demikian, ditemukan banyak kegagalan ataupun umur pakai yang pendek yang disebabkan karena bahan bilah tersebut rentan mengalami kerusakan lebih cepat akibat kondisi operasional. Dalam penelitian ini dikembangkan bahan bilah berbasis paduan besi tuang putih dengan Cr-Ni yang diberi variasi perlakuan panas, baik hardening maupun tempering, untuk meningkatkan sifat mekaniknya. Dari penelitian ini diperoleh hasil bahwa nilai optimal kenaikan sifat mekanik diperoleh melalui hardening pada suhu 1000 oC yang dilanjutkan tempering pada suhu 400 oC. Pada kondisi tersebut, sampel hasil paduan memiliki struktur fasa ferit acicular, perlite dan karbida berbentuk bulat-bulat kecil. Struktur fasa ini membuat sifat mekanik sampel menjadi lebih keras dan lebih tahan terhadap gerusan saat terjadi gesekan.

Abstract

Salah satu problematika kendaraan bermotor saat ini adalah korosi. Umumnya cat pelindung akan cepat rusak karena disebabkan kondisi operasional kendaraan pada lingkungan yang tidak menentu. Komposit coating poliuretan dengan variasi silika/karbon disiapakan, kemudian diaplikasikan pada material baja karbon rendah dengan spray gun. Pada lapisan yang terbentuk di lakukan analisis Fourier Trasform Infra Red (FTIR), Thermogravimetry (TGA), Differential Scanning Calorimetry (DSC), Mikroskop Optik dan uji salt spray. Hasil FTIR, TGA, pengamatan optik dan uji salt spray menunjukkan semakin tinggi kadar karbon/silika maka akan semakin tahan terhadap korosi.

Abstract

Logam paduan merupakan material hasil campuran antar logam, atau antara logam dengan elemen lain, yang dibuat untuk menghasilkan sifat dan karakter material logam yang diinginkan. Material logam paduan yang dibuat menggunakanCompact Arc Melter MAM–1 memiliki resiko terbuangnya sejumlah bagian (mass loss) komposisisaat peleburan. Untuk itu perlu diidentifikasi pengaruh metode peleburan yang digunakan terhadapkondisi mass loss. Dari Hume-Rothery’s Rules diketahui bahwa perbedaan jari-jari atom dan elektron valensi antara elemen pelarut dan terlarut mempengaruhi besarnya mass loss yang terjadi. Dalam penelitian ini telah dibuat logam paduan sistem Ni20Fe30Mn32Al18 (at. %)menggunakan Compact Arc Melter MAM – 1 dengan dua variasi level busur. Ditemukan bahwa penggunaan busur api level 3 menghasilkan kehilangan massa yang lebih besar dari level 4. Namun, komposisi paduan yang diperoleh dengan busur api level 3 lebih proporsional terhadap komposisi yang direncanakan dibandingkan dengan busur api level 4, yang mengalami defisit kandungan Mn. Dengan demikian busur api level 3 digunakan untuk mendapatkan paduan dengan rasio komposisi (wt. %) proporsional dengan komposisi yang direncanakan.

Abstract

Aluminum Alloy 3104 is aluminum usually used for beverage can. By modifying the content of Titanium content in the alloy, it is expected that this material will be suitable for radiator engine combustion. Especially for its corrosion behavior in coolant solution. Aluminum alloy with different content of Titanium was investigated on its crystal structure, morphology and its corrosion behavior in ethylene glycol solution which is usually used as additive in coolant water. X-ray diffractometer, Electron microscope and potentiodynamic were used to investigate the crystal structure, morphology and corrosion behavior respectively. The results show (002) crystal plane dominate the surface of the sample as the Titanium increase. The (111) and (002) crystal plane are very low compare to (022) crystal plane. Crystallite size and micro strain are affected by addition of Titanium. Surface morphology are clearly affected by the addition of Titanium. Addition of Titanium causes corrosion behavior of the samples. It concludes that the aluminum alloy with different Titanium content in this research, can be used for making radiator combustion engine.

Abstract

304 austenitic stainless steel (SS 304) is widely used in the oil and gas industry for its resistance to high pitting and stress corrosion. However, Its ability to withstand wear resistance due to fine sand particles carried by oil and gas is very limited.  Cold rolling is one of the methods used to mechanically increase the hardness of SS 304 steel. As a result of this method there is a deformation of the structure which causes a phase transformation from austenite to martensite. This change is accompanied by the formation of magnetic properties in the new phase.The increase in the percentage of deformation is followed by an increase in the magnetic saturation value and a change in the magnetic coercivity. Magnetic saturation is influenced by the large population of martensite phase formed, while the magnetic coercivity is influenced by grain shape of the martensite phase. This magnetic property will respond to an external magnetic field. So that the identification of the deformation can simply be known by observing the interaction of the SS 304 material with a magnetic object that is brought near.

Abstract

Stress concentrations cause many machine element failures. Failure will occur more rapidly if the machine elements obtain repeated and fluctuating loading. For this reason, the material for machine elements must have better fatigue life. There are various attempts made to increase material life and other mechanical properties. In this study, the research sample used is AISI 4140 steel. The samples obtain hardening followed by cooling and tempering. The hardening temperature is 8500C with a holding time of 17 minutes. The cooling media in this research are dry sand, semi-wet sand, and wet sand. Wet measurements based on volumetric ratios. Semi-wet sand with a ratio of sand and water 4: 1, sandy sand 4: 2. The final process is tempering treatment, with a temperature of 2500C. The material fatigue test refers to the JIS Z 2274 Standard. From this study, the heat treatment given can reduce the fatigue life of the material, even though the hardness increases. The higher the cooling rate, the hardness of the material increases, but the fatigue life is low.

Abstract

Suburban communities around Cilegon usually depend on urban mass transportation. The vehicle has very high mobility when peak hours. Infrequently, this consequent collision and friction between them in the crowd of traffic jams. It causes damage or crushing of their bumper. Hence, a material that has suitable qualifications is needed. One of the materials which have the potential strength to be applied as a bumper car is ramie fiber. As a fiber, this material has high tensile strength properties. In this research, we need to ensure that woven ramie-epoxy composite has a tensile strength value above the standard for car bumper material. The composite consists of woven ramie as the matrix and epoxy resin as the filler at a weight ratio of 40:60. Application curing treatment to the composite with 0-30-60-90-minute. The tensile test results are 30.6 MPa, 36,4 MPa, 36,5 MPa, and 40,8 MPa - the highest values at 90-minute CT. All tensile strength value of the composite is above the standard value required. It also found that the composite water absorption was below the limit of the standard. Based on those values, the woven ramie-epoxy composite can be considered a potent material for use as a bumper car.
