Iinfluence of Authigenic Carbide on Microstructure and Properties of Hadifield Steel
The authigenic carbide on the microstructure and properties of hadifield steel was studied by preparing authigenic carbide with ferrovanadium,graphite and rare earth as additives put into D256 welding electrode.The statistics show that authigenic carbide is evenly distributed among austenitic matrix,which can contribute to its hardness accretion to 64 HRC.Consequently,the wear-resistance was improved to 4 times higher than D256 clad.
