specimens material to investigate the influence at cryogenic treatment on
the wear resistance of the steel. The cutting tool specimens prepared by
conventionally, sub-zero and cryogenically have been used for evaluation
on the flank wear of the cutting tips by turning the hot rolled AISI 1045
steel on the comparison bases.
Further, TEM examination was used for investigating the
microstructure change during cryogenic treatment. The experiment results
evidenced that the cryogenic treatment improved the preferential
precipitation of fine ε-carbides. The fine ε-carbide particles distributed
uniformly in the matrix of martensite promoted the strength and
toughness of the martensite matrix so as to increase the wear resistance of
the tool steel.
