Structural changes in Cr-V ledeburitic steel during austenitizing and quenching

Original language description

The Vanadis 6 PM Cr-V ledeburitic steel was austenitized at temperatures from the range 1000 - 1200 oC and nitrogen gas quenched. Structural changes were investigated by light microscopy and SEM. Obtained result fixed that the M7C3-carbides underwent a complete dissolution in the austenite while MC-phase remained almost completely unaffected. The saturation of the austenite by chromium and partly vanadium induced formation of increased portion of non-martensitic structural components after quenching, due to decrease of MS and Mf temperatures. Undissolved part of MC-carbides, located mainly on the grain boundaries, hinders effectively the grains coarsening also at higher austenitizing temperatures.
