摘要：

The interface. precipitation has been observed as row carbide arrange since 1960' s. Whereas the interface. precipitated carbides in steels were NbC, TiC, VC and Cr23C6 in the early stage, composite TiC containing Mo and W has been also become to observe recently. Several kinds of the mechanism of the interface. precipitation have been suggested and ledge mechanism and bowing mechanism which combined interface barging and carbide precipitation are widely accepted since the mechanisms successfully explained a large amount of the experimental results. Fine interface. precipitates in low carbon steel realize high strength steel sheets, plates, bars and rods which are non. quenched and tempered. Especially, in sheet products, in which fine carbides can be easily generated, ferritic steel of 1180 MPa in tensile strength is successfully obtained by dispersing fine carbides with the diameter of several nano. meters.
