Abstract

The cooling rate of the water atomized powders of M3/2 high speed steel was calculated to be 105-107 K/s. In the size range of the atomized powders, the microstructure consisted of equiaxed crystals and continuous network-like carbides between the equiaxed grains. The matrix of the powders was principally austenite; as the particle size decreased, the matrix changed from austenite to a composite consisting of austenite and δ-ferrite. The types of carbides were mainly cubic MC and close-packed hexagonal M2C.
