반응고 가압단조 방법에 의한 자동차 부품 성형해석 = The Moulding Analysis of Automobile Parts Alloy to the Semi-solid Pressure Forging Die-casting Method

다국어 초록 (Multilingual Abstract)

In a recent trend where an industry is highly advanced and an environment preservation is emphasized, They also perform various researches on improving production process and developing new systems. In the pressing forging process among the semi-solid casting process, heated aluminum alloy turns into a semisolid state mixed with solid and fluid around at the fusion point. The solid is achieved in dendrite which remains in a fine solid state of globular shape stuck together. If it is placed in the mold, it maintains its shape independently like the solid. If it is pressed, it comes to have the state similar to the fluid and consequently is easily cast in the metal mold. It also aims to estimate the exact casting state of product through Super forge 2005, a program to interpret finite factors in order to perform forge die casting of plate in the middle of valve body in the car automatic transmission. Furthermore, it assesses the change of the distribution and transformation ratio.
