Abstract

Copper has been widely in many applications such as heat exchangers due to mechanical and physical properties. In this work, the composite foam was fabricated by powder metallurgy method with fly ash powder and egg yolk as a foaming agent and reinforcement, respectively. Mechanical properties of the specimen were characterize using a compaction test. Moreover, observation of the specimen was conducted using the measurement of shrinkage and porosity. The strength of the specimen was obtained in the range 1:1,25 is 0,26 MPa through compaction test. Porosity measurement revealed that maximum and minimum porosities are 88.79 % and 71.53%, respectively. Optical Microscope and Scanning Electron Microscopy observation size of the pores ranging from 21,63μm to 169,7μm. Moreover, some crystalline phase was observed using X-Ray Diffraction Test.

Abstract

Formula Society of Automotive Engineers (FSAE) is a competition where the students design, build, and race the formula-style car. In this competition, the regulation stringent for the safety of participants. Chassis is one of the regulated parts among the other parts. This paper examines design process followed by chassis analysis by using Solidworks 2018 and Abaqus/CAE 6.14 software. The analysis process is carried out with Static Vertical Test, Torsional Stiffness Test, and Crash Impact Test using a safety standard in the form of a safety factor that must be more than 1 (SF> 1) to ensure the safety of the driver. The aim is to obtain an optimum final design based on FSAE Japan regulation as a reference for the Universitas Sriwijaya electric car team, namely Sriwijaya Eco in making the framework for the upcoming electric formula car.

Abstract

Material mechanical behavior is critical for both safety and economic considerations. Because engineering items are manufactured using appropriate grade materials, mechanical approval of the materials used must be completed before assembly. Petrochemicals, marine, and biomaterials are just a few of the industries that use stainless steel. Despite its extensive use, structural failure is still frequently caused by inadequate stainless steel type selection. As a result, dangerous conditions, resulting in personal harm or financial loss. Dangerous conditions is might result in accidents, resulting in personal injury or financial loss. Martensite stainless steel is a type of stainless steel with a high strength value but is brittle, necessitating careful handling. Intergranular corrosion, sensitization, tempering heat treatment, and the Ductile to Brittle Transition Temperature (DBTT) are topics still working on Martensite stainless steel for researchers.

Abstract

The mechanical and physical characteristics of gray cast iron are intricately bound to its application as an essential material in manufacturing various goods. SMAW (Shielded Metal Arc Welding) is the most simple and widely used electric arc welding method. In this work, ASTM A48 gray cast iron Class 40 was joining using the SMAW method with the welding position used was 1G or underhand position. The joining used is the Butt Joint using an open Singel V seam with a current of 120A. The joining of Welding was characterized through dye penetrant and hardness tests. Rockwell hardness tests on base metal and heat affected zone reveal that the heat affected zone has the highest hardness value of 56.5 HRC, while the base metal has the lowest hardness value (41 HRC). Graphite, pearlite, and pearlite were all visible in the microstructure study.

Abstract

The Water Treatment Plant (WTP) is a water purification system designed to meet the water demands for power generation and operational requirements in the petrochemical industry. The current pipeline network in the Demin Plant unit employs carbon materials with rubber cladding, which presents drawbacks, such as extended recovery times during system failures. To address the issue, the research explored welding SS 304 and SS 316 materials as an alternative to the existing carbon pipes with rubber cladding. The study utilized the Taguchi experimental design method, employing an orthogonal array (L9) table to optimize quality improvement while minimizing costs. The experiment included 9 test specimens with three repetitions, examining four welding parameters, each with three levels. Variance (ANOVA) was analyzed using the Minitab software and manual calculations in Microsoft Excel. The results indicated that the factors influencing the corrosion rate of the specimens include the welding method, electrode type, welding speed, and welding current. ANOVA results showed that the welding method (F-value = 5.9176) and welding current (F-value = 8.3492) significantly affected the corrosion rate, whereas the electrode type (F-value = -3.5949) and welding speed (F-value = -2.8321) did not. A confirmation experiment yielded an optimal corrosion rate of 3.0231 mm/y, lower than experiment number 7.

Abstract

This work evaluates the feasibility of using the Temper Bead Welding (TBW) method with the Half Bead technique as an alternative to Post-Weld Heat Treatment (PWHT) for welding A335 Grade P22 pipes. Three treatment methods were compared: preheating, preheating with TBW, and preheating with PWHT. Hardness testing is carried out using the Vickers microhardness testing method. The only preheat method showed the highest hardness values in the HAZ (342 HV), fusion zone (357 HV), and weld metal (334 HV). TBW with the half bead technique had higher hardness only in the base metal (191 HV). PWHT provides the most uniform hardness distribution, effectively relieves residual stresses, and homogenizes the microstructure. TBW reduced HAZ size by 50% more than preheating. The microstructure observed in all methods was ferrite and pearlite, with differences mainly in grain size. Although TBW is a viable alternative for repair, this method is unsuitable for application in early fabrication processes.
