Abstract
This study aimed to investigate the wear performance of laser direct energy deposited Fe-8Cr3V-2Mo-2W alloy under various wear environments, in terms of different heat treatment conditions. Ball on disk tribology tests were performed using high-carbon steel and zirconia balls as counter materials. The wear rates of the alloy depended significantly.....

2020;58(8):560-565. Published online 2020 Jul 27
DOI:
https://doi.org/10.3365/KJMM.2020.58.8.560
Abstract
This study investigated the influence of laser shock peening without coating (LSPw/oC) on the degradation of copper electrical contacts. A theoretical calculation of the plastic-affected depth (PAD) induced by LSPw/oC was performed, based on the laser-induced plasma pressure along with the Hugoniot elastic limit of our LSPw/oC experimental conditions. The.....

https://doi.org/10.3365/KJMM.2017.55.12.845
Abstract
In this research, we studied the effects of Ni, Ti, and B on the elastic modulus of hypereutectic Al-Si alloys and successfully synthesized 100 GPa Al casting alloys by designing various alloys phases. Generally, Al–Si based alloys are known in the automotive industry to be good casting alloys with high.....
