This work presents a Mg-0.9Mn-0.5Ce alloy with a high strength-thermal conductivity synergy achieved through low-temperature extrusion. The alloy demonstrates high tensile strength and thermal conductivity, which can be attributed to the combined effect of ultra-fine grains, dense precipitates, and residual dislocations.
This work reported a Mg-0.9Mn-0.5Ce alloy (wt.%) with high strength-thermal conductivity synergy developed by low-temperature extrusion. The high tensile yield strength (328 MPa) and ultimate tensile strength (381 MPa) was attributed to the combined effect of ultra-fine dynamic recrystallized (DRXed) grains, dense nanoscale precipitates and high-density residual dislocations retained in unDRXed grains. The high thermal conductivity (120.8 W/m center dot K) was derived from the massive dynamic precipitation of solute atoms from Mg matrix.
