The results show that two-dimensional longitudinal section of internal fatigue microcrack has evolved from initial thinly elliptical one into arrays of spherical voids, controlled by surface diffusion.
结果表明:随保温时间的延长,内部疲劳微裂纹的纵剖面二维形态发生了主要由表面扩散控制的形态演变,由初始的扁椭圆型截面形态演化为由多个定向排列的球形空洞组成的球洞串截面形态,在横剖面上可观察到初始裂纹体分解为“外围圆环+环内球洞”的形态演变图象。
