| Abstract Scope |
Hybrid material structures offer the possibility of combining different material properties and thus meeting diverse functional requirements in one single component. Here, particular attention must be paid to the transition zones between the metallic compound partners. These transition zones need to show homogeneous and materially bonded structures to ensure ideal transmission of material properties and to prevent component failure due to material defects. In this respect, an innovative process for producing hybrid components has been developed in which a powder metallurgical route is combined with semi-solid forming technology. The aluminium alloy AlSi7Mg0.6 (A357) is heated into the semi-solid state and subsequently formed onto a porous copper green body. In order to analyse the connection mechanisms, copper green bodies of varying densities were used, resulting in different joints of the components. The paper deals with thermal properties of components produced in this way. |
