Quantitative analysis on friction stress of hot-extruded AZ31 magnesium alloy at room temperature : = Quantitative analysis on friction stress of hot-extruded AZ31 magnesium alloy at room temperature
Mg alloy AZ31 with ~79%(volume fraction of scattering less than 30?) basal-fiber texture through hot extrusion exhibits strong grain-size dependent yield strength. Samples with grain sizes varying from4.5 to 22.3 ηm were obtained by altering annealing time durations. The Hall-Petch relations of tension and compression are σ_(0.2)= 86+200 d~(-1/2) and σ_(0.2)= 17 + 327 d~(-1/2), respectively. Considering the correlation between grain orientation and deformation modes, a novel weighted average method of calculating friction stress 0 was proposed, and results of calculation agreed with the experimental ones, which can reasonably understand the yielding behavior in tension and compression..
