WebThe effect of Nb depends on the austenisation temperature which governs the amount of MX precipitates which is taken into solution. Tantalum: Ta, as Nb, is a ferrite stabilising element which forms stable MX precipitates with C and N. The Ta-rich MX precipitates were found to be beneficial to the creep rupture strength. WebThe austenisation and quenching behaviors of a medium-Mn steel with a chemical composition of C 0.14% and Mn 5.0% were presented in this paper. The heating and holding temperature varied from 500OC to 950OC was applied to find the austenization temperature. The holding time varied from 1-5minutes was used to choose the suitable austenisation …
