Abstract
Cryogenically treating tungsten carbide tooling has the capability of extending tooling life, however, the mechanism of that extension has not been established. This study analyzes the microstructural alterations of the eta, gamma, and alpha phases within the carbide (WC) tooling caused by the treatments, and links these changes to the corresponding tool life. Of the four turning tool types investigated, two types had a decrease in life due to the treatment, one type had a slight increase, and the last type had a significant increase. The microstructural analysis shows that all three phases influence the tool life. Moreover, the combined influence of the phases phases is shown to dictate tool life. Thus, by knowing the treatment effect on the tooling, the corresponding tool life can be predicted prior to being used in production.
