Effect of precipitation hardening treatment on hardness and tensile behaviour of stir cast LM4 hybrid composites through TEM and fractography analysis

Effect of precipitation hardening treatment on hardness and tensile behaviour of stir cast LM4 hybrid composites through TEM and fractography analysis

LM4 hybrid composites reinforced with TiB2 and Si3N4 are fabricated using a two-stage stir casting method and are subjected to precipitation hardening treatment. The efficacy of TiB2, Si3N4, and precipitation hardening treatment on LM4 was investigated. When compared to as-cast LM4, all hybrid compo...
