本文用正电子湮没技术和透射电子显微镜（TEM）研究了α-Fe中氢致开裂的机理。结果表明，氢空位复合物促进了微孔洞的形成，微孔洞在阴极充电过程中沿α-Fe晶界沿着聚集长大，从而引发微裂纹。研究了这种微裂纹的热稳定性。
The mechanism of hydrogen cracking in α-Fe has been studied by positron annihilation technique and transmission electron microscopy (TEM). It was revealed that microvoids were promoted by hydrogen-vacancy complex, and microcracks were initiated by coalescence and growth of such microvoids along grain boundaries of α-Fe during cathodic charging. The thermostability of such microcracks was also studied.
