“…Therefore, only a small fraction of the simulated volume is deformed plastically and a significant strain incompatibility is expected. [7,10,19]. Two distinct stages can be observed.…”

“…for crystals oriented with one of the h1 1 1i axes along the loading direction, {1 0 0} slip traces have been observed within the channels. Activation of cube slip systems has important consequences for the models of the orientation-dependence of the mechanical response [14][15][16][17][18][19]. Adopting cube slip is a convenient scheme to account for the softer plastic response of nonh0 0 1i oriented specimens.…”

“…room temperature, and high volume fractions of small y7 precipitates, plastic deformation has been suggested to begin in the y'-phase [9]. Several studies have demonstrated that the break down of Schmid law is a characteristic feature not only for the y'-phase with the L12 structure, but also for all superalloys containing a high, medium or even low volume fraction of the 7'-phase [10,11]. It has been shown that the degree of anisotropy depends on the test temperature as well as the size and shape of the y'-precipitates [2,12] The yielding anisotropy of the superalloys has been attributed to the non-Schmid effect of the y'-precipitates [13].…”

“…Cube slip for the γ matrix is included primarily to reflect zig-zag cross slip, as noted by Osterle and Bettge (2000). The structure of the evolution equation for dislocation density is similar to that of the precipitate phase, except that no locking or unlocking terms are present.…”
