The features of this dissertation are lie in: a The concept of"Influence Distance"was presented to quantitatively express"corner effect", systematicly studied on the influence of all factors on"influence distance". It could provide reference to angle designing from the view of heat treatment; b Deeply studied on the influence of shape factor to carbon concentration field. It could provide reference to gear designing from the view of heat treatment; c New model was set up to describe the two-dimensional concentration field of carbide dispersion carburizing. The shortcomings of"effective diffusion constant method"and"equilibrium constant method"were overcome in this model.
