Abstract Scope Excellent room temperature formability and satisfactory strength need to be simultaneously achieved to broaden the application of magnesium sheet alloys. This presentation reports the ideal microstructure and optimum composition as heat treatable alloys in Mg-Zn based Mg-xZn-0.2Zr-0.3Ca (x=1~5 wt.%) (ZKXx00) alloys. Although the yield strength increases with increasing the Zn content, the Index Erichsen (I.E.) value, which is an indication of formability, decreases considerably in a T4 condition. Additionally, the time to reach a peak hardness remarkably shortened to less than an hour with decreasing the Zn content as the main strengthening phase changes from MgZn2 to Guinier Preston (G.P.) zone enriched with Zn and Ca. Therefore, the dilute ZKX alloys are demonstrated to be ideal heat treatable sheet alloys. Further compositional and process optimization lead to higher I.E. value over 8 mm with yield strength of 220 MPa after aging.
