An Overview of the Development of Al-Si-Alloy Based Material for Engine Applications
نویسنده
چکیده
The development of Al-Si alloy and its based material for engine application is reported in this paper, focusing on improving the material’s fatigue limit and wear resistance, which are two important properties for engine block materials. The paper begins with a description of the microstructure (primary and eutectic phases, intermetallics, and casting defects) of Al-Si alloy and its effects on this material’s fatigue and wear behaviors. Then, some recent techniques to enhance these two properties are discussed such as alloying, composite production, and casting.

متن کاملDENDRITE FRAGMENTATION IN THE SHEARED MELT BY FATIGUE EROSION MECHANISM OF SEMISOLID Al-Si ALLOY (A.356.0
Over the last few decades, there have been many mechanisms proposed to describe the formation of the non-dendritic microstructures during Semisolid Metal (SSM) processing; including dendrite fragmentation, spherical growth, cellular growth and recalescence. Dendrite fragmentation is the most popular mechanism of all these hypotheses. It is the purpose of the present article to examine the morph...

متن کاملTHE INFLUENCE OF DRY SLIDING ON PRCIPITATION HARDENING BEHAVIORS OF Al-Cu-Si ALLOY
Abstract: Cold working performed before an aging treatment has a significant effect on size and amount of precipitate produced. This could be caused by the increase in defect density, such as vacancies and dislocations. In this research, the Al-Cu-Si alloy was solution-treated, wear-tested and then artificially aged for a period of 1–5 h. Changes in the amount of precipitate, in the lattice par...
