| Abstract: | Use OM,SEM technology of new multi-element alloying Cr5 support rolls on the microstructure observation and analysis,and combined with performance.The test results show that: after 450 ℃ tempering sample first increased and then present the hardness down trend,divided into two stages,low temperature area with the quenching temperature to rise high,with the rise of quenching temperature drop.Quenching temperature of 970 ℃ or so,can obtain uniform organizations and higher hardness.Multi-element alloying elements in the organization,carbide amount is more,carbide close,even,surface deformation distribution and spalling phenomena is less. |
