THE INFLUENCE OF MAGNESIUM …

01.01.1991· Silicon carbide particle-reinforced composites containing either commercial purity aluminium (1070) or aluminium-1wt% magnesium (5050) matrices, were tensile tested. It was found that fracture in the Al-1070 matrix composites proceeded by SiC fracture and by interfacial decohesion in the Al-5050 matrix composites.

Fabriing large-scale mirrors using …

09.08.2016· To create an even larger mirror, we investigated the use of reaction-formed joint technology. 7 In large-scale mirrors, the joints between mirrors must have good mechanical strength and environmental stability that are comparable with the bulk materials (the monolithic silicon carbide green body). To achieve this, we joined silicon carbide green bodies with a slurry of silicon carbide
