摘要
应用TEM弱束技术，测得Ll2结构的Ni74.5Pd2Al23.5合金（111）和（100）面的反相畴界APB能分别为（144±20）mJ／m2和（102±11）mJ／m2．实验数据与Ni3Al的APB能数据接近因此，Ni74．5Pd2Al23．
Using the TEM weak beam technigue,the APB energies on the (111) and (100) planes of Ni74.5Pd2A123.5 alloy with L12 structure were determined to be(144±20) mJ / m2 and (102±11) mJ/m2 respectively.The relation of ordering energies on the ductility of the alloy was also discussed in this paper.
