| Abstract: | By way of resolving nonisothermal diffusion equation, a theoretical formula for non equilibrium grain hboundary segregation has been dierived, and the relationship among width of boron depleted zone, quenching temperature,cooling rate,activation energy and diffusion constant of non equilibrium grain boundary segregation has been established.The theoretical prospects breed with experimental result satisfactorily. |
