1)micro-indentation微压痕

2.Investigations of the plasticity,damage and fracture induced by micro-indentation are reviewed.主要结果:微压痕诱导硅和砷化镓晶体的纳米和非晶转变,并发现这一转变的临界应力;转变过程是由切应力,并非静水压力控制;电子辐照诱导非晶晶化,并发现晶化临界条件;晶化速率与电流密度有关;压痕诱发的裂纹尖端不是原子尖的,其萌生与扩展伴随位错的产生,并由此引发点阵的畸变,并产生1～2nm宽非晶带;裂纹扩展沿非晶带发生,而非裂端前方原子键相继断裂的结果;经傅立叶变换和逆变换发现,裂纹尖端变形显示出各向异性。
