Thixomolding of Particulates Reinforced Metal Matrix Composites
입자 강화형 금속 복합재료의 Thixomolding
Abstract
The characteristics of thixoforming process can decrease liquid segregation because of the improvement in fluidity in a globular microstructure state and utilizes flow without an air entrapment. Therefore, in order to obtain the sound parts of metal matrix composites by using thixoforming process which is co-existing solidus-liquidus phase, it is very important to obtain a die design, fabrication conditions which affects the uniformity of the solid fraction on unfilling state and various defects throughout the fabricated parts. The die designs and fabrication conditions to obtain the good piston part are proposed for thixogorging process of metal matrix composites.
