of the cooling slope. However, the cooling slope has some disadvantages, such as the adhesion of the metal. The relationship between the casting factors and the adhesion has not been investigated precisely. In the present study, the influences of the casting factors on the adhesion of the metal at the cooling slope were investigated. The casting factors were nozzle size to pour the melt, distance between......

forming [2-4]. Now, semi-solid metal processing has been combined with casting[5] to produce complex geometry components with improved mechanical properties. The main requirement for alloys to be shaped... the alloy is cooled in a metal mould with the same cooling rate. The ingot with non-dendritic microstructure can be prepared by near-liquidus casting process with a pouring temperature of 595 ℃ of the melt......
