홈페이지논문 초록 (Abstract)
The structural and hardness variations of Mg-5Sn-(1,2,3) Ca (wt%) alloys have been investigated during various aging heat treatments followed by solution heat treatment at 500 C for 24 hrs. Maximum hardness of Hv61 has been obtained for Mg-5Sn-3Ca alloys, when the aging treatment was performed at 200 C for 24 hrs. The microstructures were critically changed when the content of Ca was more than 1wt% , since CaMgSn and Mg2Ca phases were mainly precipitated during aging treatments. The hardness variations with structural evolutions are discussed with respect to the aging temperatures and times.
