- Abstract
- The microstructure and tensile properties of bi-materials consisting of the unreinforced magnesium, the macro-interface and composite reinforced with SiC whiskers were investigated. The macro-interface has diffuse interface characteristics, its thickness is about 7∼10 μm. It has been found that the tensile strength of the bi-materials at R.T. is lower than that of its corresponding pure magnesium and the composites, and remains unchanged until 423 K. Above 423 K, the tensile strength decreases with increasing temperature and becomes the same as that of magnesium. The elongation is in between the pure magnesium and the composite at R.T. and elevated temperatures. These results were discussed based on the experimental observation of fracture surface by FE-SEM.
