Moreover,in situ observations of slip trace were supplemented by the direct observation of dislocation arrangements under TEM.In B-doped Ni_3Al alloys it is shown that close to the grain boundary there exists a thin slip transition region,within which slip lines are reoriented or other slip systems are operated to produce a local strain accommodation and to relax the stress concentration at grain bound- aries.Boron seems to lower the stress for dislocation generation from the grain boundaries or to ease the cross-slip close to the boundaries,and also to increase the number of dislocation sources.However,B-enhenced ductility is seriously affected by stoichiometry,the addition of a tertiary alloy element and heat treatment,etc..","authors":[{"authorName":"LIN
