On the determination of the stacking fault energy from extended nodes in Cu2NiZn

The effect of nitrogen on the stacking fault energy in Fe–15Mn–2Cr–0.6C– x N twinning-induced plasticity steels

“…The value of b p was determined by multiplying the measured a 0 value by ffiffi ffi 6 p =6. The e i value was assumed to be nearly the same as the b p value [32]. The value of a was measured to be approximately 36°, as determined by the angle between a node arm ([002]) and its Burger vector (1=6 ½11 2).…”
