摘要
Abstract
For multi-layer plate ,it is a difficult problem to increase product yield rate and improve bonding interface quality .A high yield hot-rolled method of multilayered plate was proposed .The raw strips and plate were fixed by argon arc welding .The combined billet was put into a metal box and vacuum pumped ,and then heated and rolled by multi passes at the temperature of 1000-1200℃ .The 67 layered plate with the thickness of 2 .5mm was successfully produced .The interfacial microstruc-tures and diffusion behavior were investigated and analyzed by optical microscopy and scan electronic microscopy .The tensile and shear strength were tested ,and the shear fractures were analyzed .The results show that the multilayered plate yield rate is more than 90% by two steps billet combination method and rolling process optimization .The good bonding interface quality is obtained ,the shear strength of multilayered plate reaches 241MPa .Nickel interlayer between 9Cr18 and 1Cr17 can not only prevent the diffusion of carbon ,but also improve the microstructure characteristics .关键词
