Micromechanics mechanism of two α-Fe models with and without a/2〈111〉{110} edge dislocations is investigated under a constant strain rate of 109s−1 at 800K with 0.1at.% He by molecular dynamics simulations. The results show that micromechanics behaviors are tailored by pressure release of He clusters and subsequent He bubbles coalescence. Furthermore, it is interested to notice that yield stress and...
