DOI:
https://doi.org/10.3365/KJMM.2023.61.7.534
Abstract
The physical properties of metal-based structural materials, such as hardness, strength and toughness, are directly or indirectly affected by residual stress inside or on the surface of the given part. Repeated rapid heating and cooling during the additive manufacturing process causes thermal gradients and expansion and contraction in the material,.....

DOI:
https://doi.org/10.3365/KJMM.2022.60.3.180
Abstract
In this study, Ti-10Mo alloy powder and sintered bodies were successfully fabricated using a threestep process of acid/organic solvent cleaning, hydrogenation/dehydrogenation (HDH) of bulk Ti-Mo scrap, and pressureless vacuum sintering of the alloy powder. This process can be used to recycle valuable Ti alloy. And unlike remelting-based recycling processes, in.....

Abstract
The deformation mechanism at room temperature in water quenched (WQ) and furnace cooled (FC) mild steels was investigated in a plane tilted 45° from the tensile direction, using electron back scattered diffraction, XRD, and TEM. The occurrence of (211) twinning was confirmed by pole figures and the slip systems were.....
