FUNCTIONAL MODEL AND TECHNIQUE FOR SERIES PARTS MADE FROM LIGHT ALLOYS BY THIXOTROPY

Abstract

The papers aim is to present the constructive solution of a functional model that makes complex parts by thixotropy process as well as their manufacturing process. Our functional model was used to develop, by pressing when the material reaches a dens plasticization state, in a matrix, light alloys made from Mg-Al obtained from recycling car wheels. The experimental lot characteristics, thus obtained, are detailed in the present paper and highlight a significant growth in performance, compared to previous parts, obtained by classic casting.

The metallographic structure of injected parts is type thixotrop, a lot different from the dendrite structure of cast parts. Resistance to compression-tearing is net superior if compared to cast parts, which facilitates applying the manufacturing process to products that have small geometry.
