Strain-induced aging strengthening in dilute magnesium alloy sheets

摘要

(A) (wt%): 0 to 3.0 Zn; 0 to 1.5 Ca; 0 to 1.0 Zr; 0 to 1.3 rare earth elements or mixtures thereof; 3 is a step of preparing a dilute magnesium alloy sheet containing a magnesium alloy consisting essentially of Sr; 0 to 0.7 Al, the balance Mg and other inevitable impurities, wherein the total weight% of alloying elements is 3 And (B) a dilute magnesium alloy sheet is plastically deformed such that the tensile plastic strain is greater than 0.5% but less than 8% to form a predeformed magnesium alloy sheet. And (C) aging the pre-deformed magnesium alloy sheet at a temperature range of 80-250 ° C. for at least 1 minute, thereby forming a reinforced magnesium alloy sheet. How to strengthen a non-alloy sheet. [Selection] Figure 8
