Influence of Reheat Temperature And Holding Time on The Interaction Of V, Al, And N in Air-Cooled Forging Steels

by: Lee M. Rothleutner; Colorado School of Mines, 2012
Description: In this study, a medium-carbon vanadium microalloyed steel (38MnSiVS5) with three different Al levels (0.006, 0.020, and 0.031 wt pct) was used to examine the interaction of vanadium, aluminum, and nitrogen during the reheat cycle for forging.

Cooling Behavior of Microalloyed Forging Steels Report

Description: Microalloyed forging steels require cooling rates greater than still air to obtain the best form of precipitates and increase strength. This study, supported by the Forging Industry Educational and Research Foundation, determined the critical cooling rates to produce interphase precipitation that results in peak hardness value for three different steel forgings alloys – 15V30M, 38MnVS6 and 15V41.
