图17. 反相畴界(APB)切割和层错切割的示意图[32]
Fig.17. Schematic drawing of antiphase boundary (APB) and stacking fault (SF) shearing mechanisms[32] (DE—increased interface energy per deformed unit area in system; fγ’III—volume fraction of tertiary γ’ precipitate; f c1 γ’III, f c2 γ’III—volume fraction of tertiary γ’ when temperatures are Tc1 and Tc2; Tc1, Tc2—temperature)
(a) γ’ precipitates sheared by APB, small solid circles and large circles denote tertiary and secondary γ’ precipitates,respectively
(b) γ’ precipitates sheared by SF
(c) DE corresponding to APB shearing and SF shearing mechanisms as a function of fγ’III
(d) DE corresponding to APB shearing and SF shearing mechanisms as a function of temperature
