Title: Stress corrosion cracking of several hot-rolled binary Mg-X alloys

Abstract

The stress corrosion cracking (SCC) of hot-rolled Mg0.1Zr, Mg0.1Sr, Mg1Mn, Mg0.3Si, Mg5Sn, Mg0.7La, Mg0.9Ce, Mg0.6Nd, Mg6Al, Mg5Gd and Mg0.3Ca in distilled water (DW) was studied using the linearly increasing stress test (LIST). Hot-rolled Mg1Mn and Mg0.7La had some SCC susceptibility in DW. All the other hot-rolled Mg-X alloys had little SCC susceptibility in DW. There was no obvious difference of the fractography between the specimens tested in air and in DW. Here, the increase of SCC resistance by hot-rolling was related to improvement of the microstructure.
