利用循环纳米压痕技术研究了单晶硅在卸载过程中的相变。在不同的残余载荷下观察到不同的相变，导致在不同位置出现弹出，这是以前从未报道过的。通过分析压痕位移-时间曲线斜率的变化，探讨了再加载过程中的相变机理。(C)2015 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Phase transformations in single crystal silicon were investigated by cyclic nanoindentation with controlled residual loads in the unloading process. Different phase transformations were observed at different residual loads, leading to appearance of pop-outs in different positions, which has never been reported before. Phase transformation mechanism in the reloading process was discussed by analyzing the slope change in the indentation displacement time curve. (C) 2015 Acta Materialia Inc.
