| Abstract: | In this paper,the effects of different ageing process parameters after fast cooling of austenitic nitrocarburizing of low carbon free cuting steels on microstructure,microhardness and mechanical properties is stu died The results showed that,after artificial ageing,the combined effects of precipitation hardening in the inside compound layer and the phase transformation in hardening layer may be induced on the nitrocarburized and fast cooling low carbon free cuting steels This process is one of the effective method for small size parts to surface hardening |
