摘要： <正> A new category of steel with excellent combi-nation of strength,toughness,strain-hardeningability and excellent resistance to high-stress,espec-ially to severe impact-loaded abrasion has been de-veloped with a new idea of abrasion-resistant ma-terial design.The steels have the microstructures ofaustenite film and bainitic ferrite laths in arrange-ment of extremely fine lath spacing and arechemically high-carbon low alloy ones.The effectsof austempering temperatures on microstructures,mechanical properties,wear-resistance andbehaviour of the austenite-bainite steels inimpact-abrasion system have been emphaticallystudied.
