Mo与4340不锈钢真空扩散焊接的研究
RESEARCH OF VACUUM DIFFUSION BONDING IN MOLYBDENUM AND 4340 STAINLESS STEEL
摘要
Abstract
The joining of Mo and 4340 stainless steel without interlayer and with Ni foil as interlayer were carried out by vacuum diffusion bonding respectively .Microstructures, element distributions and hardness in joints were analyzed by Scanning Electron Microscope and Energy Dispersive X-Ray Spectroscopy .The results indicated that the properties of the joints boned without interlayer were inferior due to hard and brittle Fe-Mo intermetallic com-pounds formation.The joints microstructure and properties were markedly improved when Ni foil was used as inter-layer.The high shear strength of 196 MPa was found in the joints with Ni foil interlayer , which is increased by 115%in comparison with that of directly bonded counterparts .关键词
