Abstract

Failure may occur catastrophically by fracture along grain boundaries when temper embrittlement induced by non-equilibrium, grain-boundary segregation (NGS) of phosphorus atoms. Temper embrittlement control technique based on the theory of NGS and deformation induced phase transformation in low-alloy steel, 12CrlMoV (which is used in steam pipeline of ships), was experimentally investigated. A single-pass hot rolling process by using a Gleeble-1500 system was performed, and the experimental results showed that the grain sizes were obviously affected by the deforming temperature, strains, strain rate and the quenching cooling rate. Temper embrittlement may be controlled and obviously improved by grain refinement.
