| 摘 要： | 通过在氧化钨粉中添加铼酸铵的方法制得新型钨合金坯条，再经垂熔、旋锻和拉伸等工艺研制出高温抗震钨铼丝。经实验优选，钨中铼的最佳添加量为3％（质量分数）。所研制的灯用Φ0．02mm钨铼丝，其抗拉强度，延伸率，抗震和抗下垂性能均优于国内目前广泛使用的WAL1和WAL2钨铝丝。本工艺钨铼丝的尺寸偏差和表面质量达到GB4181-84标准的规定。从方坯条到成品丝的统计成品率，新工艺钨铼丝为88．7％，钨铝丝是88％。

| Abstract: | Adding NH4ReO4 in the WO3 powder to produce new tungsten alloy billets,then the W-Re alloy wire for shock-resistance at high temperature was prepared by the process of high temperature sintering,rotary swaging and drawing.The test results show that the optimum addition of rhenium is 3%.The tensile strength,elongation,droop-resisting for the lamp-wire of 0.02 mm in diameter is better than that of WAl1 and Wal2 which is widely used in our country at present.The finished products' ratio of W-Re wire made by this process is 88.7%,and that of W-Al wire is 88%. |
