Effect of Austempering-Partitioning on the Bainitic Transformation and Mechanical Properties of a High-Carbon Steel

The 1.1C-1.5Si-1.1Mn1.4Cr-0.5Mo-0.6Al-0.6Co （in wt%） steel was treated, respectively, by isothermal austempering process and newly developed austempering-partitioning-tempering process （A-P-T）. After austempering at 250, 280 and 300 ℃ for 38, 20 and 10 h, respectively, the sample microstructures wer...
