摘　　要：通过传统退火和电流退火改变Fe_(78)Si_(9)B_(13)非晶合金薄带的塑性,对退火样品进行纳米压痕测试和塑性成形试验,验证两种退火工艺下Fe_(78)Si_(9)B_(13)非晶合金薄带的性能和成形效果。结果表明,当两种退火工艺的温度相同时,Fe_(78)Si_(9)B_(13)非晶合金薄带经电流退火后的硬度和弹性模量较低,塑性成形效果更佳,其中300℃电流退火20 min后的纳米压痕位移最大,非晶合金塑性变形行为的改善也最为明显。The plasticity of Fe_(78)Si_(9)B_(13)amorphous alloy thin strip was modified by conventional annealing and current annealing.Nanoindentation tests and plastic forming tests were carried out to evaluate the properties and forming effect of Fe_(78)Si_(9)B_(13)amorphous alloy thin strip under the two annealing processes.The results show that when the temperatures of the two annealing processes are the same,the hardness and elastic modulus of the Fe_(78)Si_(9)B_(13)amorphous alloy thin strips after current annealing are lower,and the plastic forming effect is better,in which the nanoindentation displacement after current annealing at 300℃ for 20 min is the largest,and the improvement of the plastic deformation behavior is also the most obvious.
