The consolidation Mg-Gd-Y-Zn-Zr billets containing long period-stacking ordered(LPSO)phase were recycled from the metal chips through the spark plasma sintering(SPS)process,which achieves the effective metallurgical bonding between metal *** effects of the sintering parameters on the microstructure characteristic and mechanical properties of the recycled billets were *** metal chips were effectively bonded in the recycled billets sintered at 500°C,however,the metal chips partly melted into semi-solid state as sintering temperature increased to 550°*** oxidation films of rare earth(RE)element formed at the bond interface between metal chips during SPS recycling *** consolidation recycled billets through SPS demonstrated the rival compression failure strain and superior compression stress compared with the referenced cast *** lamellar 14H-LPSO phases hardly precipitate in the vicinity of the bond interface between metal chips after heat treatment with air ***,the furnace cooling facilitates the precipitation of 14H-LPSO phases within the a-Mg grains,even the a-Mg matrix adjacent to the bond *** oxide films at the bond interface between the metal chips were zigzagged and fragmented during the isothermal *** cracks or holes were hardly observed adjacent to the bond interface during isothermal compression,which reveals superior bond properties and deformation consistency performance between metal chips.c 2020 Published by Elsevier *** behalf of Chongqing University.

Microstructure and mechanical properties of Mg-Zn-Y-Zr alloy prepared by solid state recycling

Machined chips of Mg-Zn-Y-Zr alloy were consolidated by cold pressing and then hot extrusion under various processing temperatures and extrusion ratios. The results show that the microstructure of the chip-extruded alloy is marked by a large number of recrystallized grains and some unrecrystallized grains, which results in high strength but low ductility at temperatures below 320 ℃. With increasing processing temperature up to 360 ℃, entirely recrystallized and equiaxed grains are obtained. Mg-Zn-Y-Zr alloy with low strength but high ductility is obtained compared with the alloy processed at low temperature. At 420℃, coarse and equiaxed grains are formed, which results in the drastic decrease of mechanical properties. With increasing extrusion ratio from 8 to 16, the grain refinement is more obvious and the mechanical properties at room temperature are improved effectively. However, the yield strength and ultimate tensile strength are improved a little with further increasing extrusion ratio.
