| Abstract: | The phenomenon that quenched boron and the boron in steel cluster to austenite grain Boundaries is non-equilibrium grain boundary clustering.By the way of resolving no isothermal diffusion equation,a mathematical expectation for non-equilibrium grain boundary clustering has been derived,and the relationship among measure of boron depleted zone,quenching temperature,cooling rate,activation energy and diffusion coefficient of non-equilibrium grain boundary clustering has been established.The consequence from the theory agreed with experimental result. |
