Abstract

Attempts are made to treat 45 steel cryogenically using liquid nitrogen. Various properties of un-treated and cryo-treated 45 steel are studied in a comparative manner. The morphological changes are investigated by metallurgical microscope. Hardness is evaluated by the relevant machine. The results reveal that the micro-structure of 45 steel become compact and homogeneous during the cryogenic treatment, and the interlamellar spacing of pearlite become smaller. The cryogenic treatment is found to be an effective technique for enhancing hardness and wear performance.
