THE APB ENERGIES OF Ni_(74.5)Pd_2Al_(23.5) ALLOY WITH L1_2 STRUCTURE
L12结构Ni74.5Pd2Al23.5合金的反相畴界能

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.
