摘要
采用共晶钎焊工艺对Mg/Cu异种材料进行连接,研究了不同保温时间对接头微观组织及力学性能的影响。结果表明,在焊接温度为500℃、保温时间为30 min、焊接压力为2 MPa的工艺下,焊接接头最高抗拉强度为54 MPa。
Magnesium alloy and copper were bonded by eutectic contacting reaction brazing, and the effects of holding time on the microstructure and tensile properties were studied. The results from the experiment show that when the welding process is 500 ℃ keeping for 30 rain, welding pressure is 2MPa, the tensile strength can reach 54MPa.
