【摘要】 本文研究了非晶态Ni₈₃Cr₇Fe₃Si₄B₃合金在动态加热及等温热处理条件下的晶化过程。结果表明,对于动态加热及等温热处理两种情况,镍基非晶态合金的晶化过程相同,结晶相没有发生变化。但是,在动态加热条件下,初始晶化主要是成核结晶,而在等温热处理晶化过程中晶粒长大起主要作用。更多还原

【Abstract】 The crystallization of amorphous Ni₈₃Cr₇Fe₃Si₄B₃ alloy was investigated under dynamic heating and isothermal annealing conditions. An identical crystallization and unaltered phases are revealed under both treatments. However, the initial crystallization is mainly due to the nucleation of crystals under dynamic heating, while the crystal growth plays a major role under isothermal annealing. It has also been measured that the microhardness approached its highest value just before the specimen being totally crystallized.更多还原
