The Effect of Heat Treatment on Interface Properties of S45C Steel/Copper Compound Casting
ABSTRACT 
 
The bonding of an S45C steel inserted into copper during cast welding and heat treatment was examined. The interface shear strength was made with a push-out test. After cast welding, a cast-welding layer formed between steel and copper. After marquenching, martempering and austempering heat treatment, there was a cast-welding layer near the steel matrix, an irregular layer near the copper matrix and between of them was a middle layer. Through X-ray diffraction analysis was used to determine that the interface layer consisted of carbon and CuFeO2. Through electron probe X-ray microanalysis (EPMA), it was showed that iron atoms and carbons, mostly, diffused into the copper matrix. The interface shear strengths of the compound casting while with marquenching, martempering, and austempering were 6.29 MPa, 8.23 MPa, and 8.33 MPa, respectively; The fractured region was all happened near S45C steel matrix in the cast welding layer.
Microstructural characterization of interafaces in fibre-reiforced ceramics
Abstract A survey is presented of the principles underlying the design of model interface microstructures which have the required micromechanical response and thermal or environmental stability within fibre-reinforced ceramic matrix composites. Microstructural and compositional characterisation of interfaces, based on electron imaging and spectroscopic techniques, are reviewed with illustrative examples of interfaces formed by in-situ reaction during fabrication or by fibre precoating.
