摘要

The effect of the cooling rate after austenitizing on both the microstructure and the creep rupture strength of low C-2.25Cr-1.6W0V-Nb steel were investigated. As the cooling rate became lower, the as-normalized microstructure changed from bainitic ferrite (α_B) to granular bainitic ferrite (α_B) with polygonal ferrite (α_p). the hardness of material after austenitizing followed by cooling at rates of 0.09 to 6.94Ks~-1 and tempering was found to be about 190HV. Hardness was low at cooling rates of 0.03Ks~-1 or under because of the increased volume of ferrite.
