Al-Si cast alloys are widely used in the automotive industry, especially for structural elements, crankcases and cylinder heads. However, these applications presume continuous efforts to improve the high-temperature performance of the various alloys. As weight reduction and the request to reduce exhaust emissions have become a key issue for the automotive manufacturers, there is an increasing demand for Al-Si cast alloys with improved properties concerning yield and tensile stress at elevated temperatures.

For almost two years now, the Institute of Nonferrous Metallurgy, in cooperation with AMAG casting and the Universities of Zurich, Aachen and Vienna, has been dealing with the topic “high-temperature strength” with the objective of a full understanding of the strengthening mechanisms working at high temperatures. The aim of the present work is the development of an easily castable and economically competitive hypo or near-eutectic Al-Si cast alloy tolerating high scrap addition.
