In this paper, the analysis of engine mounting structures that will be applied to electric vehicles is conducted. The structure subjected static loading from mounted components assembly, including assembly gearbox, motor, and corresponding brackets. arrangement, HSLA material mostly used general structural steel such as AISI 4130 also used. This study aims evaluate existing design so further op...

In this study, the main task is to identify best cutting parameters improve machining performance during MQL-turning with various fluids like coconut oil, ground nut sunflower soyabean and blassocut oil. Cutting temperature surface roughness were used as metrics, goal of minimizing these responses. To construct an experimental plan for turning AISI4130 uncoated brazed carbide, full factorial de...

In this study, the effect of quenching and partitioning (Q&P) heat treatment on structural mechanical properties AISI 4130 steel was investigated. The Q&P process followed at a quench temperature 270 oC three different temperatures 270, 330, 380 oC. phase characterization prepared spicimens were done using X-ray diffractometer (XRD) scanning electron microscopy (SEM), respectively. samples also...

This study focuses on the processability of four low-alloy steels (AISI 4130, 4140, 4340 and 8620) via laser-based powder bed fusion (LB-PBF). In as-built condition, alloys consisted tempered martensite that was result an intrinsic heat treatment (IHT) during LB-PBF. terms defects, a distinct transition in porosity observed correlated to volumetric energy density (VED). At low VED, specimens co...
