The effect of vanadium on the reversible temper-embrittlement behaviour of low-alloy chromium and chromium-nickel steels
Description
The effect of vanadium on the susceptibilities of chromium and chromium-nickel steels to reversible temper embrittlement was evaluated. The steels investigated were approximately equivalent to steels of BS 970 Grade 708A42 and BS 970 Grade 817M40, the major difference being that molybdenum had been replaced by vanadium in various concentrations. It was found that the vanadium had a detrimental effect and, in all the concentrations tested, enhanced the susceptibility to reversible temper embrittlement of both the chromium and the chromium-nickel steel. The detrimental role played by vanadium in reversible temper embrittlement is explained by a consideration of the effect of vanadium carbide, as well as of free vanadium, in solid solution in ferrite
