TENSILE STRENGTH AND CREEP RESISTANCE OF Mg-9Al-1Zn BASED ALLOYS WITH CALCIUM ADDITION

1. IntroductionIn the paJst decade cast magnesium alloys have enjoyed a renaissance in many manu-facturing industries, especially the automotive and electronic ind.stri.s1--4]. However, theuse of magnesium alloys for engineering applications is still restricted to a few structuralparts although they offer lightweight, high stiffness, excellent machinability and the bestalternative fOr weight reduction4]. The principal technical challenge to the widespreaduse of magnesium castings in structu…
