Aimed to the defects of liquid phase segregation, microporosity, misrun and dross revealed in semi solid rheoforming, the size and structure of chamber, billet, gate runner, bob and gas release system were optimized and studied in detail. Based on mentioned above study, a set of general mould for testing sample in semi solid rheoforming was designed. The mould can be used for various conventional alloy testing samples in semi solid rheoforming, including tensile, impact, fatigue, fracture toughness, ab...
