| Abstract: | Due to the defects of toughness infusing area after the friction welding, by five heat treatments. we observed the metallogic structure and tried out the mechanical property. It proved that the heat treatment models just after welding can improve the comprehensive mechanics prosperty of fusing area, which leads to the average anti-tension intensity with 691 MPa, the average percentage elongation with 18.6% and the average value of shock with 40 J/cm2. |
