摘要：用透射电镜和衍射电镜测量了镍、td -镍和Inconel 600薄箔中相干孪晶界-晶界相贯体系的孪晶界自由能与晶界自由能之比δtb/δgb。镍的δtb/δgb校正后的最终平均值分别为0.031、0.025和0.022。分别为td -镍和Inconel 600。通过对镍、td -镍和Inconel 600的孪晶界自由能δgb的实验测量和估计，分别约为27,27和19ergs /cm2。
Abstract The ratio of the twin boundary free energy to grain boundary free energy, δtb/δgb, for coherent twin boundary-grain boundary intersecting systems in thin foils of nickel, TD-nickel, and Inconel 600 has been measured by transmission and diffraction electron microscopy. Final, corrected mean ratios of 0·031, 0·025 and 0·022 for δtb/δgb were obtained for nickel. TD-nickel and Inconel 600 respectively. Using experimentally measured and estimated values of δgb, the twin boundary free energy δtb, for nickel, TD-nickel and Inconel 600 was observed to be approximately 27, 27 and 19 ergs/cm2 respectively.
