Processing and microstructure–property relations of high-strength low-alloy (HSLA) Mg–Zn–Ca alloys

[Display omitted] Deformation dilatometry and semi-industrial extrusion were used to investigate the effect of different thermomechanical processing routes on the microstructure and mechanical properties of the low-alloy Mg alloys ZX10 (Mg–1Zn–0.3Ca) and ZX00 (Mg–0.5Zn–0.15Ca). It is shown that the...

Zusammenfassung:[Display omitted] Deformation dilatometry and semi-industrial extrusion were used to investigate the effect of different thermomechanical processing routes on the microstructure and mechanical properties of the low-alloy Mg alloys ZX10 (Mg–1Zn–0.3Ca) and ZX00 (Mg–0.5Zn–0.15Ca). It is shown that the deliberately adjusted formation of intermetallic particles beneficially influences dynamic recrystallization and grain growth, with the result of a fine-grained microstructure (grain size
