The local chemical composition of composites consisting of alternating layers of Co28.2Fe38.9Cr15.4Si0.3B17.2 and Fe53.9Ni26.5B20.2 amorphous alloys subjected to torsion with increasing number of revolutions (true plastic strain) at high quasihydrostatic pressure in a Bridgman anvil cell is studied by time-of-flight mass spectroscopy. Three-stage transformation of the structure of composites with an increase in the strain is revealed. It is found that the average microhardness of the composite at a certain stage of machining exceeds the microhardness of its individual amorphous alloy components. The nature of the observed effects is discussed in terms of the features inherent in severe plastic deformations.

高压扭转作用下非晶合金层状复合材料组织的三阶段演变及非添加剂硬化效应

由 Co 28.2 Fe 38.9 Cr 15.4 Si 0.3 B 17.2和 Fe 53.9 Ni 26.5 B 20.2交替层组成的复合材料的局部化学成分通过飞行时间质谱法研究了非晶合金在高准流体静压下在布里奇曼砧室中随着转数(真实塑性应变)的增加而扭转。揭示了随着应变的增加复合材料结构的三阶段转变。结果表明,复合材料在某一加工阶段的平均显微硬度超过了其单个非晶合金组件的显微硬度。观察到的效应的性质根据严重塑性变形的固有特征进行了讨论。
