Effect of vanadium and austenitising temperature on hardenability of (0·2–0·3)C–1·6Mn steels with and without additions of titanium,aluminium,and molybdenum
The hardenability of steels containing 0·2–0·3%C, 1·6%Mn, up to 0·3%V (all wt-%), and microalloying additions of Ti, Al, or Mo has been examined using the standard Jominy test, the results from which were used to calculate the ideal critical diameters. For each steel composition, the relationship between the ideal critical diameter and austenitising temperature in the temperature range 950–1150°C was established. For chosen austenitising temperatures, the multiplying hardenability factors for vanadium were calculated. The experimental results are discussed on the basis of a proposed model concerning the mechanism of hardenability, particularly applicable to microalloyed steels.
