ajst-21750	Song, Xiaoya; Yu, Min	Effect of Hydrogen Embrittlement on Dislocation Emission from A Bifurcation Crack Tip in Nano-metallic Materials	2024	7	.pdf	application/pdf	5638	374	66	[26] utilized a molecular dynamics simulation method to investigate the emission of crack tip dislocations in Ni single and crystalline samples in a hydrogen environment. When the relative crack length is taken as b/a=0.2, 0.3, 0.5, 0.7 and 0.9, the corresponding dislocation easiest firing angle is θmin =1.1 rad; and when the dislocation firing angle is taken as a certain value, it increases with the increase of temperature, which leads to more difficult emitting of crack tip dislocations, and thus reduces the toughness of the material due to dislocation emitting. 0.000 0.002 0.004 0.006 0.008 0.010 0.6 0.8 1.0 1.2 1.4 C0 (mol) m=1/5 m=1/3 m=2/3 0 ΙCK Figure 4.	cache/ajst-21750.pdf	txt/ajst-21750.txt
