摘要: Abstract The microstructure and impact behavior of A356 aluminum alloy were studied after melt treatment processes grain refinement modification under both non-heat treated T6 heat conditions. done with the addition Al–10%Sr Al–5Ti–1B master alloys, respectively. All casting parameters kept constant in order to focus on influence mentioned treatments. results indicate that eutectic silicon morphology is main parameter control alloy. Consequently, individual as-cast does not improve toughness as does. While, simultaneous provide higher comparison improves all melt-treated This related further particles. To verify clarify mechanisms, three-point bending test fractography used interpret improvement
