摘要：

The presence of cobalt in high speed steels is of great interest to researchers and the users as well. Although cobalt bearing high speed steels are used on commercial basis, the influence of cobalt in cryogenically treated high speed steels is still under scanner. Some researchers have found the effect of cobalt as negative, as it adversely affects the wear properties and fracture toughness of some high speed steels under certain conditions. This paper takes a review of influence of cobalt in tool steels with the past research and discusses the experimental results of the effect of cryogenic treatment on 10%Co bearing AISI T42 high speed steel. It has been found that this steel has an advantage due to the presence of Cobalt with respect to wear characteristics after the cryogenic treatment. It is also found that the cycle time of cryogenic processing of this super high speed steel shortens due to the presence of cobalt.
