Abstract

The paper presents results of determination and industrial verification of cooling cycles in thermomechanical processing (TMP) of steel AISI 4130, designed to produce good combination of strength and ductility directly after forging and quenching. The results indicate possibility of replacement costly high alloy steels with common grades offering higher strength in combination with good plasticity after cost-effective TMP cycles utilizing blast-air cooling from controlled forge end temperature.
