The mechanism of nucleation of unfaulted vacancy loops (VL) with Burgers vector b = 〈100〉 in bcc-metals is suggested. The mechanism takes into account the experimental fact that the nucleation of such loops takes place exclusively in the cascade region of damage. In substantiating the ...
In both cases, the absorption is assisted by a flip of the loop Burgers vector. The simulations also show that double superjogs lock the dislocation ... D Rodney,G Martin - 《Physical Review B》 被引量: 101发表: 2000年 Solving the puzzle of interstitial loop formation in bcc Iron. 2 ...
I. Theoretical predictions for edge dislocation loops in a BCC crystal images are possible for this simple elastic defect model but that useful image classifications can be made in terms of modulus g.b where g is the reciprocal lattice vector of the operating reflection and b the dislocation ...

ferritic/martensitic steelHT9The interstitial loop is a unique signature of radiation damage in structural materials for nuclear and other advanced energy systems. Unlike other bcc metals, two types of interstitial loops, 1/2111 and 100, are formed in bcc iron and its alloys. However, the ...
