Macro- and Microstructural Studies of Laser-Processed WE43 (Mg-Y-Nd) Magnesium Alloy

The Effect of Scanning Strategy on the Thermal Behavior and Residual Stress Distribution of Damping Alloys during Selective Laser Melting

“…It can be seen that the values of the thermophysical properties of WE43 tend to undergo rapid changes around melting point, e.g., a rapid drop in density and thermal conductivity and a rapid rise and fall in specific heat, but the rest of the parts basically remain linear (in spite of the rapid changes due to melting; with the increase in temperature, density tends to decrease, thermal conductivity tends to increase, and specific heat remains constant). The results obtained from the software generally agree with the results of others’ research [ 49 ] and in the engineering handbooks [ 52 , 53 ], although some larger variances in thermal conductivity could be observed due to the difference in specific element compositions [ 54 ].…”

“…However, such research on Mg-RE alloy is seldom seen. Rongrong Xu et al [ 35 ] conducted similar research on a Mg-Y-Sm-Zn-Zr alloy, but for WE43; only some previous research concerning WE43 products’ melt pool dynamics [ 48 ], macro-/microstructure [ 49 ], and mechanical testing results [ 50 ] has been published. In this article, the scanning strategy analysis of WE43 deepens our understanding of the material’s characteristics.…”

Friction stir additive manufacturing for high structural performance through microstructural control in an Mg based WE43 alloy

“…Thermal conductivity of H13 tool steel and WE43 at the mean temperature was obtained by interpolating the temperature dependent values existent in the literature [50,51]. Preheat during the tool plunge has been assumed as negligible and the initial temperature is substituted as 298 K.…”

Additive friction stir deposition of AZ31B magnesium alloy

“…Vickers hardness of the samples was measured in the crosssection. This research formed as a part of a decade long effort by the present group focusing on the advanced processing of Mg alloys [2,8,21,22,[35][36][37][38][39][40][41][42] . It provided a successful pathway towards fabrication of Mg alloys using AFSD technique and methodology for realizing processing-structure-property relationships in AFSD produced materials.…”
