Abstract:By means of a Mo-Fe-Ni-Co diffusion quarternary and the B-type spline functions, the mathematical models of the components have been established on the two-dimensional plane of the diffusion quarternary for the six single-phase regions δ-MoNi,P,μ-Fe7Mo6,bcc(Fe),bcc(Mo) and fcc in the Mo-Fe-Ni ternary system, and for the four single-phase regions δ-MoNi,μ-Co7Mo6,bcc(Mo) and fcc in the Mo-Ni-Co ternary system.

 

Key words: Mo-Fe-Ni-Co diffusion quarternary mathematical models concentration distribution B-type spline functions
