    • Abstract
  • In this article, the mechanical properties, creep damage, creep rupture strength and features of interfaciaL failures of welded joints between martensite (SA213191) and pearlite steel (l2Crl MoV) have been investigated by means of argon tungsten pulsed arc welding, high temperature accelerated simulation, creep rupture, mechanical property tests and scanning electronic microscopy (SEM).The research results indicate that the interface between weld and l2Crl MoV steel is the weakest part of welded joint.However,the interfacial failure tendency of low match welded joint is less than those of medium and high match welded joint.Therefore,it is resonable that the low match welding material is used as the filler metal of weld between SA21T91 and l2Crl MoV steel.
