摘要： In a preferred embodiment of the invention, a process is disclosed for producing a compound aluminium alloy engine block casting (10) which comprises at least a piston-travel region (26) of a cylinder wall section (18) formed of a first alloy, preferably hyper-eutectic aluminium-silicon alloy, and a remainder including a crankcase section (12) and a water jacket wall (20) formed of a distinct second alloy, preferably hypo-eutectic aluminium-silicon alloy. The engine block casting (10) is made by a lost-foam process that employs an expendable pattern (32) formed of expanded polystyrene or the like. The pattern comprises a first runner system (50) for casting the first alloy to decompose and replace a portion of the pattern corresponding to the piston-travel region (26) of the casting, and a second runner system (60) for casting the second alloy to decompose and replace the remainder of the pattern (32). The first alloy and the second alloy are independently but concurrently cast into a single mould (30), such that the entire pattern (32) is duplicated, whereupon the alloys merge and fuse to form an integral casting (10). The preferred product engine block casting (10) advantageously combines the high wear-resistance of the hyper-eutectic aluminium alloy in the cylinder wall section (18) and the reduced porosity and improved machinability of the hypo-eutectic alloy throughout the balance of the casting (10).
摘要翻译：在本发明的优选实施例中，公开了一种用于生产复合铝合金发动机块铸件（10）的方法，该铸造件至少包括由第一合金形成的缸壁部分（18）的活塞行进区域（26）优选超共晶铝硅合金，其余包括曲轴箱部分（12）和由不同的第二合金，优选低共晶铝硅合金形成的水套壁（20）。发动机块体铸造（10）通过使用由发泡聚苯乙烯等形成的消耗型图案（32）的缺失泡沫工艺制成。图案包括用于铸造第一合金以分解和替换与铸件的活塞行进区域（26）相对应的图案的一部分的第一流道系统（50）和用于铸造第二合金合金分解并替代图案（32）的其余部分。第一合金和第二合金独立地同时浇注到单个模具（30）中，使得整个图案（32）被复制，随后合金熔合并形成一体的铸件（10）。优选的产品发动机阻挡铸件（10）有利地将超共熔铝合金的高耐磨性（在汽缸壁部分（18）中）和低共晶合金的低孔隙率和改进的机加工性整合到铸件的整个平衡（10）。
