摘要：The randomly textured Mg-Al-Zn alloy processed by electron beam welding typically exhibits clear grain size dependence of yield strength according to the Hall-Petch relationship: sigma(0.2) = 62 + 202d(-1/2). The Schmid factor for the basal slip system was deduced to be around 0.031 in the randomly textured Mg alloys. The sigma(0) in the Hall-Petch equation was theoretically calculated to be similar to 65 MPa, which is reasonably consistent with the experimental data of similar to 62 MPa.
