非晶合金,在高温退火后产生相分离,由自由能较高的相向自由能较低的相转变.本文对PdSi_(20),PdSi_(20)Cr_7非晶合金,在高温炉中,由室温到700℃进行连续升温的X射线测量(每隔20～50℃测量一次)得出:PdSi_(20)非晶合金,在45℃时析出Pd原子聚集团,65℃对PdSi原子集团聚集,85℃时Pd_2Si原子集团聚集,145℃时Pd_3Si原子集团聚集.
Amorphous alloys, which are phase-separated after annealing at high temperature, have lower free-energy phase transitions due to the higher free energy.In this paper, PdSi_ (20) and PdSi_ (20) Cr_7 amorphous alloys were sintered in a high- X-ray measurements (measured every 20 to 50 ° C) of continuous heating at 700 ° C gave PdSi 20 amorphous alloy precipitated Pd clusters at 45 ° C and aggregated Pd 65 clusters at 65 ° C, ℃ Pd_2Si atomic group aggregation, 145 ℃ Pd_3Si atomic group aggregation.
