| 摘 要： | 在K403合金基础上通过铸锻工艺制备出连续挤压机用新型堵头模具材料——GH403合金,然后对GH403合金的组织结构和力学性能进行了观察分析,并在TLJ400型连续挤压机上采用GH403合金堵头进行了应用实验.结果表明:GH403合金组织均匀,具有良好的强韧综合性能,可以满足铜镁合金的连续挤压需要；在连续挤压高强度铜镁合金过程中,其挤压寿命比H13高出17倍,具有良好的性价比.

| Abstract: | A new abutment mold material GH403 alloy for continuous extrusion was fabricated by casting and forging processes based on K403 alloy.Then the structure and mechanical properties of GH403 alloy were observed and analyzed.Furthermore,the application experiment was finished on TLJ400 type continuous extrusion machine using GH403 alloy abutment.The results show that GH403 alloy has uniform microstructure and good comprehensive performance in the aspects of strengthening and toughening,which can meet the need of continuous extrusion of copper magnesium alloy.In the continuous extrusion process of high strength copper magnesium alloy,GH403 alloy abutment has well cost-effective because of good extrusion life which is 17 times higher than that of H13 steel. |
