摘要: 通过传统退火和电流退火改变Fe78Si9B13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Fe78Si9B13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,Fe78Si9B13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。

Abstract: The plasticity of Fe78Si9B13 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 Fe78Si9B13 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 Fe78Si9B13 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.

Key words: Fe78Si9B13 amorphous alloy, current annealing, nanoindentation, properties, plastic deformation
