Effects of Concentration of the Alloying Element Co on the Mechanical Properties of NiAl AITranslate
Abstract AITranslate
Calculation and analysis were made of the effects of Co concentration on the mechanical properties of NiAl alloy based on virtual crystal approximation and using the first-principles pseudopotential plane- wave method. The results from elastic modulus calculation and analysis show that after B2-NiAl crystal is alloyed with Co, its hardness is increased except x （Co） = 2%, and obviously increased in the low concentration range of x（Co）=0-0.5 %, and the increase degree is lower in the high concentration range of x（Co）=3-25%. At the same time, the ductility of B2-NiAl crystal is decreased at first and then increased,decreased only a little at x（Co） =0-0.5% and obviously at x（Co）=0.5%-4 % ,and increased gradually at x（Co） =4%-25%.
