16. Masafumi Hamasaki, Hirofumi Miyahara, Solidification Microstructures and Critical Conditions of Shrinkage Porosity Generation in Die Casting Process of JIS-ADC12 (A383) alloy, Materials Transactions, Vol.54, No.7, 1131-1139, 2013.07, Differential thermal analysis (DTA), analyses of unidirectional solidification process and die casting process, and computational numerical simulation were conducted for JIS- ADC12 (A383) alloy to investigate the generation conditions of the shrinkage porosities which occasionally appear in JIS-ADC12 die castings and affect the quality of products. The crystallization temperature of the primary alpha phase and Al-Si binary eutectic phase are estimated to to be 856K and 838K from DTA, respectively. The multi-phase eutectic reaction of JIS-ADC12 alloy starts from 826K, and finishes at 801K. The primary alpha dendrites are clearly observed in unidirectional solidification microstructures, and the relationship between the secondary dendrite arm spacing and local solidification time can be expressed by the following equation. The primary alpha dendrites are also observed in the cast sample. The average cooling rate estimated from is approximately 60K/s at the depth of 0.5mm from the surface of die castings. The computational numerical simulation revealed that the values of solidification parameter increased around the surface of the JIS-ADC12 die casting in where the amount of shrinkage porosities decreases. Especially, shrinkage porosities of the size larger than 200μm is observed when the value of is less than or equal to 1.4 K0.5s0.5/mm..
