【摘要】 本试验研究了SiMnV、SiMnP、SiMn和SiMnVTi等双相钢的显微组织和性能的关系。前二者属退火双相钢,后二者属热轧双相钢,以SiMnVTi钢正火性能最佳。更多还原

【Abstract】 The relationship between microstructure and mechanicalproperties of Si-Mn-V, Si-Mn-P, Si-Mn and Si-Mn-V-Ti dual phase steels has been investigated. The first two are the annealed dual-phase steels, the other two arc the hot rolled dual-phase sbeels. The Si-Mn-V-Ti dual-phase steel has better comprehensive properties in normalized condition.更多还原
