Abstract
The effects of Mg on wear resistance of SiCp/Al-Si-Mg composites were studied. Comparative analyses between equivalent von-Mises stresses and yield stresses of α-Al and SiC were calculated, and quasi-in-situ observation were conducted to reveal the wear behavior and modes. During reciprocating frictions, the matrix with better plasticity is the weak part in composites. Due to the deformation discontinuity, the interface between SiC and matrix tends to separate leading to surface cracks and wear failure. Therefore, increasing the strength of α-Al and improving the deformation coordination between α-Al and SiC are the crux to improve wear resistance. 1 wt% Mg addition introduces Mg-Si GP zones and B′ precipitates into α-Al, resulting in precipitation strengthening which improves the wear resistance of composites.
期刊介绍：
Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
