| 摘 要： | 系统研究了纯钼丝和镧钼丝在不同温度下进行热处理后的组织与性能。结果表明，La2O3是镧在钼丝中的唯一存在形式，镧的添加，提高了丝材的室温强度和再结晶温度，改善了再结晶后的室温脆性，其综合性能明显高于纯钼丝。

| Abstract: | The microstructu r e and properties of pure molybdenum(PM)w i res and Mo-La(LM) wires heat-treated at different temperature have been investig ated.It is shown that La 2O 3 is a uniqu e existing form of La in the molybdenum wires.La 2O 3 can enhance the room-tempe rature strength of the Mo-La wires and i ncrease the temperature of recrystall ization.The low-temperature embitterment of Mo-La wires heat-treated at high tem perature is improved and the comprehensi ve properties of the LM wires are better than that of the PM wires. |
