| 摘 要： | 对掺杂一种（以下简称：单元）或一种以上（以下简称：复合）稀土氧化物的钼粉、坯条及不同温度退火丝材的性能及组织结构进行了系统研究。结果表明：复合稀土同单元稀土一样，都能提高钼丝的再结晶温度，复合稀土钼丝表现出优异的高温退火强度，并具有比同含量的单元稀土钼丝更高的延伸率，具有更好的成型性和加工性。

| Abstract: | The systematic study has been made on the properties and microstructures of rare earth doped molybdenum powders,bars and annealed wires.It is shown that the recrystallization temperature of molybdenum wires was increased greatly by addition of either one oxide or two oxides. Compared to one oxide doped molybdenum wire,the two oxide doped molybdenum wire presents lower strength,but higher elongation.This is very helpful to the formation of molybdenum cathode. |
