用半硬度法和金相观察测定了Pd与若干Pd-RE合金的再结晶温度,用图象法测定了上述合金的再结晶晶粒度。试验结果表明,所有稀土元素明显提高Pd的再结晶温度和细化晶粒,并计论相关的机制。
The recrystallization temperatures of Pd and some Pd-RE alloys were measured by semi-hardness and metallographic observations. The recrystallization grain size of the alloys was determined by the image method. The experimental results show that all rare earth elements significantly increase the recrystallization temperature of Pd and refine the grains, and discuss the related mechanisms.
