用葛摆测量了ａ－ＰｄＣｕＳｉ合金的内耗－温度曲线，证明在该合金的Ｔｇ和Ｔｘ温度附近有两个内耗峰Ｐ１和Ｐ２．Ｐ２峰是与非晶晶化有关的内耗峰，而Ｐ１峰可能是弛豫型的内耗峰．分析了倒扭摆和Ｃｏｌｌｅｔｔｅ摆的灵敏度，阐述了这两种摆不适用于测量ａ—ＰｄＣｕＳｉ类合金的内耗峰．
The internal-temperature-temperature curve of the a-PdCuSi alloy was measured with the Ge Pseudo-pendulum and it was shown that there are two internal friction peaks P1 and P2 near the Tg and Tx temperature of the alloy. The P2 peak is the internal friction peak related to the amorphous crystallization, and the P1 peak may be a relaxation type internal friction peak. The sensitivity of inverted pendulums and Collette pendulums is analyzed, and the two pendulums are not suitable for measuring the internal friction peaks of a-PdCuSi-based alloys.
