Achieving breakthrough high strength in AZ31 magnesium alloy bar via a novel single-pass extrusion process

AZ31 magnesium alloy generally suffers from insufficient room-temperature strength. Meanwhile, conventional processing routes offer limited strengthening efficiency, and severe plastic deformation (SPD) processes face difficulties in industrial upscaling. To address these bottlen...

Anomalous deformation behavior and underlying mechanisms of Mg-Nd-Zr-Ca alloy during low-temperature hot compression

The anomalous deformation behavior of a Mg-1.8Nd-0.4Zr-0.3Ca (wt%) alloy during hot compression at low temperatures (180–330 °C) and strain rates of 0.001–10 s⁻¹ was systematically investigated. The flow stress exhibits an abnormal increase with decreasing strain rate at 180 °C,...
