Abstract
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，Ni74.5Pd2Al23.5 合金塑性的提高与合金 APB 能的大小无明显关系
Using the TEM weak beam technigue, the APB energies on the (111) and (100) planes of Ni74.5Pd2Al23.5 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.
