摘要：

Tungsten (W) was joined to ferritic/martensitic steels (FMSs) by hot isostatic pressing (HIP) with interlayers consisting of Ti or Cr coatings and inserted Ti and Cu films. The effects of interlayer type and post-HIP heat treatment (PHHT) on the joining properties of W/FMS were investigated by evaluating the joining strength and analyzing the interface microstructure. The W/FMS joint specimens with the inserted Ti films showed a higher shear strength than those with Cu films, irrespective of the coating layer type. The complicated interface microstructure with many diffusion layers in the W/FMS joint led to a decrease in the joining strength. The effect of PHHT was different depending on the interlayer type employed in the HIP joining. PHHT was beneficial especially for the HIP joined W/FMS with Ti(2 mu m)/Ti(50 mu m) interlayers when it was properly performed to avoid a split at the interface in an edge of the HIP joined block.
