Mechanical properties and microstructure of heat-treated samples of A356 and AA2024 aluminum alloys, which were rheoforged by varying the change in pressure and temperature were investigated, preventing defects such as porosity, liquid segregation, and insufficient filling occurring during rheoforging process. The rheology material was fabricated by an electromagnetic stirring process by controlling stirring current so that shearing force and temperature of the molten metal were controlled during electromagnetic stirring. As a result, by crushing dendrite and rosette type microstructures, fine and globularized rheology material was obtained and the feasibility of the rheoforging process was found to be positive. In the case of the direct rheoforging process, excessive applied forging-pressure caused material spattering, which in turn caused eutectic segregation. This segregation brought about a shrink hole and thus led to a deterioration of mechanical strength. According to varied applied forging pressures, agglomeration phenomena of primary particles of wrought aluminum alloy remarkably increased as compared with an as-cast aluminum alloy.

Composite Carbon

The search results of a carbon-graphite-aluminum alloy composite of aluminum carbide Al4C3 and the possibility of controlling the formation of this undesirable phase by organizing a diffusion transition layer are presented. The problem is shown and ways to solve it are proposed for the impregnation of carbon graphite with aluminum or its alloys. For the study, samples were made by impregnating a porous carbon-graphite frame with a cast aluminum alloy.
