摘要

摘要: 本文研究了Fe40Ni40P12B8非晶合金冲击波加载下的晶化行为，冲击波由二级轻气炮发射的告诉弹丸撞击靶产生。实验结果表明：Fe40Ni40P12B8非晶合金在冲击波加载下，晶化可在加载时间（微秒量级）内发生；晶化的阈值压力在30~50 GPa之间，相应的冲击温度约为510~800 K，晶化析出相与冲击压力有关，低压下析出相是面心立方-(Fe, Ni)固溶体和Fe3(P0.37B0.63)化合物，高压下（大于60 GPa）析出相除了面心立方-(Fe, Ni)固溶体和Fe3(P0.37B0.63)化合物之外，还包括(Fe, Ni)3P化合物。

Abstract: The shock-induced crystallization of amorphous Fe40Ni40P12B8 alloy was investigated in this paper. The shock loading condition was produced by the impact of high velocity projectile, which had been accelerated by a two-stage light-gas gun to a definite velocity. The experimental results indicated as follows: (1) the crystallization of amorphous Fe40Ni40P12B8 alloy can be induced under the shock loading in about 10-6 s duration; (2) the threshold pressure of crystallization is 30~50 GPa, and the correspondent temperature is 510~800 K; and (3) the precipitated phases depends on the pressure applied, at lower pressure the phases are -(Fe, Ni) solid solution and Fe3P type Fe3(P0.37B0.63) compound, at higher pressure (higher than 60 GPa) the phases are -(Fe, Ni) solid solution and two Fe3P type of Fe3(P0.37B0.63), (Fe, Ni)3P compounds.
