【Abstract】 The shock-induced crystallization of amorphous Fe40Ni40P12B8 alloy was investigated in this paper. The shock loading condition was preduced 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 10-6s duration; (2) the threshold pressure of crystallization is 30-50GPa,and the correspondent temperature is 510-800K; and (3) the precipitated phases depends on the pressure applied, at lower pressure the phases are γ -(Fe, Ni) solid solution and Fe3P type Fe3(P0.7B0.63) compound, at higher pressure (higner than 60GPa) the phases are ;v-(Fe, Ni) solid solution and two Fe3P type of Fe3( 0.37B0.63).
