| 摘 要： | In this study,intermetallic TiAl and steel 40Cr diffusion bonded successfully by using a composite barrien layer Ti/V/Cu,In this case,a diphase Ti3Al TiAl layer and a Ti solid solution which enhance the strength of the joint are obtained at the TiAl/Ti interface.The interface of TiAl/Ti/V/Cu/40Cr was free from intermetallic compounds and other brittle phases,and the strength of the joint was as high as 420MPa,very close to that of the TiAl base.This method gives a reliable bonding of intermetallic TiAl and steel 40Cr.

| Abstract: | In this study, intermetallic TiAl and steel 40Cr are diffusion bonded successfully by using a composite barrien layer Ti/V/Cu. In this case, a diphase Ti3Al+TiAl layer and a Ti solid solution which enhance the strength of the joint are obtained at the TiAl/Ti interface. The interface of TiAl/Ti/V/Cu/40Cr was free from intermetallic compounds and other close to that of the TiAl base. This method gives a reliable bonding of intermetallic TiAl and steel 40Cr. |
