摘要：

The fracture resistance capability of aluminium die casting alloy (ADC-12) metal matrix composite (MMC) synthesize by gravity and stir cast without milling, gravity and stir cast with ball milling and 3D mix and high pressure die cast (HPDC) is evaluated and compared. Better distribution of SiC particles was found by synthesizing MMC by ball milling and 3D mixing as compared to gravity casted MMC material. It also resulted in higher strength and hardness of MMC synthesize by ball milling and 3D mixing. The current study also assessed the performance of ADC-12 MMC synthesized by three methods in terms of numerically determined initiation fracture toughness. It is found that HPDC synthesized MMC material has the best properties like hardness, strength and fracture toughness among the three synthesizing methods used in the present investigation.
