Extrusion Method

The problem of chip processing of aluminum alloy containing scandium is considered. The difficulty of remelting due to easy oxidation of the alloy components is noted. It is proposed to dispose of the shavings without transferring the metal to liquid state. The aim of the work is to construct technological scheme for the processing of waste chips of the Al—Mg—Sc alloy formed as result of machining cast billets by cutting. Results of experiments including cold briquetting, hot extrusion and drawing are presented. The mechanical properties of the product obtained according to several variants of the technological scheme are measured. The possibility of continuous drawing of semi-finished product is shown. The conclusion is made about the possibility of using the scheme in the production process.

In this paper, with a newly self-developed rotating barrel rheomoulding machine(RBRM), microstructures and mechanical properties of rheo-die casting A356 alloy were studied. In order to clearly show the characteristic of rheo-die casting, liquid die casting and semi-solid casting were done too. The experimental results showed that microstructures of rheo-die casting were composed of solid grains, which were finer and rounder, and had fewer pores. In the three technologies, integrated mechanical properties of semi-solid rheo-die casting were the best.
