Effect of reinforcement on the fracture surface of precipitation-hardened LM4 hybrid composites

The objective of this study was to compare the hardness, tensile strength, and fracture surface analysis of LM4, LM4+ (1, 2, and 3 wt.%) TiB2, LM4+ (1, 2, and 3 wt.%) Si3N4, and LM4+ (1, 1.5, and 2 wt.%) TiB2+ (1, 1.5, and 2 wt.%) Si3N4 hybrid composites. Composites were cast using a two-stage stir...
