近来,过共晶成份的铝硅合金变形半成品在工业各个部门获得了广泛的应用。特别是在电气工业部门采用了厚度为0.03～0.04毫米的A1Si18合金箔材。对箔材提出的主要要求是在合金中硅组成的分布要均匀细小分散。 A1Si18合金在铸造状态下,塑性较低,这样,在生产一定厚度的箔材时,合金的变形就会迂到困难。在熔体结晶时,采用较高的冷却速度,提高过共晶硅铝明合金的塑性是可行的。提出一种实现快速冷却并随后热
Recently, the hypereutectic Al-Si alloy deformation of semi-finished products in various sectors of the industry has been widely used. In particular, the A1Si18 alloy foil with a thickness of 0.03 to 0.04 mm is used in the electrical industry. The main requirement for foil is that the distribution of the silicon composition in the alloy should be uniformly and finely dispersed. A1Si18 alloy in the casting state, low plasticity, so that in the production of a certain thickness of the foil, the alloy deformation will be difficult to go round. In the melt crystallization, the higher the cooling rate, improve the plasticity of hypereutectic Si-Al alloy is feasible. Proposed a way to achieve rapid cooling and subsequent heat
