An Experimental Study on the Manufacturing Technology of an Engine Piston
자동차용피스톤의 제조기술에 관한 실험적 연구
Abstract
In this paper, an experimental study has been carried out to develop an aluminum forged piston which has good mechanical properties. Through the experiment, the cavity filling, microstructure and mechanical properties of the final product are investigated with respect to chosen process parameters, which are die shape, heat-treatment condition and preform shape. The mechanical properties of the forged piston are compared with these of the cast piston. As the results, an appropriate die-shape is obtained to produce a perfect piston. The suitable heat-treatment condition and preform-shape are found to good hardness and minute microstructure in the forged piston. And we could obtain the mechanical properties(tensile strength, elongation and hardness) of the forged piston are superior to these of the cast piston.
