【摘要】 在气体激波管中，利用激波对非晶的直接作用，在微秒量级时间内，成功地将ＦｅＢＳｉ、ＦｅＭｏＢ－Ｓｉ及ＦｅＣｕＮｂＢＳｉ等非晶合金转变成为纳米晶，主晶化相晶粒平均尺寸在２０－ ６０ｎｍ 范围，晶化相分数＞ ９５％ 和常规退火晶化比较，激波晶化在晶化相、晶化动力学和晶化机理等方面具有一系列独有的特点。更多还原

【Abstract】 In a gas shock wave tube, amorphous alloys FeBSi, FeMoBSi and FeCuNbBSi have been transformed into nanocrystalline materials by direct effect of shock wave on the Amorphous alloys within microseconds. The grain size of the primary phase α Fe is 20-60nm. The transformed fraction is about 95%, comparing with that of the annealing at normal pressue, there are some new properties about mechanism, kinetics, crystal phases and crystal theory in shock wave crystallization.更多还原
