Effect of deep cryogenic treatment on mechanical properties and residual stress of AlSi10Mg alloy fabricated by laser powder bed fusion

During the fabrication of AlSi10Mg alloys by laser powder bed fusion (LPBF), the high-power density incident on the melt pool locally results in rapid heating and cooling rates, which leads to residual stress inevitably. Since the residual stress can lead to defects in the LPBF-built parts, it is ne...
