Abstract：

The compound casting and forging process of aluminum alloy 6063 with different forging pressures, forging-starting time and holding time was carried out, and the mechanical property and wear resistance property at room temperature were tested and analyzed. The results show that with forging pressure increasing from 70 MPa to 150 MPa, forging-starting time increasing from 2 s to 6 s, and holding time increasing from 5 s to 35 s, the mechanical properties and wear resistance property of samples both increase first, and then decrease. Compared with forging pressure of 70 MPa, the tensile strength of alloy increases up by 42 MPa and the wear volume decreases by 18×10-3 mm3 when the forging pressure is 130 MPa. Compared with forging-starting time of 2 s, the tensile strength of alloy increases by 17 MPa, and the wear volume decreases by 7×10-3 mm3 when the forging-starting time is 6 s. However, compared with holding time of 5 s, the tensile strength increases by 29 MPa and the wear volume decreases by 13×10-3 mm3 when the holding time is 35 s. Finally, the optimal process parameters of the compound casting and forging of aluminum alloy 6063 are chosen as forging pressure of 130 MPa, forging-starting time of 4 s and holding time of 25 s.
