| Abstract: | Friction stir processing was applied to Mg-Zn-Nd-Zr magnesium alloy with 3 different parameters.The dynamic experiments for Mg-Zn-Nd-Zr alloy was carried out using the Hopkinson pressure bar,then we got the stress-strain curves of Mg-Nd-Zn-Zr alloy.We have researched the variation of the alloy fore-and-aft FSP by analyzing the stress-strain curves.The results show that the technology of FSP can improve the dynamic properties of Mg-Zn-Nd-Zr alloy considerably. |
