Abstract

The ignition point of non-combustible Mg alloy is about 300K higher than that of normal magnesium alloy. It is expected that the non-combustible Mg alloy is used in substitution for Al alloy for structures. In this paper, the fundamentals, those are a notch effect, and a long or small crack effect on fatigue strength of a non-combustible Mg alloy, are investigated. Moreover, the fatigue strength characteristics of the non-combustible Mg alloy are compared with that of Al alloy to clarify differences of fatigue strength characteristics between Mg alloy and Al alloy.
