가압회전식 장비를 이용한 A356 합금의 미세조직과 재가열 특성

Characteristics of Microstructure and Reheating of A356 Aluminum Alloy by Pressure Rotation Equipment

Many rheocasting processes had been proposed because of the difficulty of recycling, the limit of material, and the high cost of raw material in thixocasting. But, these rheocasting processes also had disadvantages such as the high initial Investment cost and the lower mechanical properties than thixocasting. In this study, a continuous fabrication of rheological material with pressure rotation equipment was newly devised to overcome the disadvantages of rheocasting process. In order to investigate the thixoformability, reheating experiments were carried out with the material fabricated by the newly devised equipment. Morphological characteristics between mechanical stirring and reheating were compared.
