Title

Improvement the mechanical and tribological properties of high temperature Al-Si-Ni alloys

Abstract

Mechanical testing plays an important role in evaluating the fundamental properties of engineering materials as well as, in developing new materials. Microstructure as light optical microscope (LOM) and scanning electron microscope (SEM) examinations were carried out on the produced alloys. Effects of Ni addition on the mechanical and microstructure properties of Al-Si cast alloys have been studied. In this study, the mechanical properties, such as the tensile strength, Brinnel hardness and wear property were investigated. The obtained results indicated that the tensile strength of Al-Si alloy without Ni increases slightly from 74 to 82 N/mm2 as the silicon contents increase. But, the addition of Ni to Al-Si alloys at the same silicon contents increase the tensile strength of Al-Si-Ni alloys from 135 to 200 N/mm2. Also, the hardness of Al-Si alloys without Ni increase from 49 to 61 HBN with increasing the silicon content but the hardness of Al-Si-Ni alloys rises from 60 to 102 HBN with addition of Ni to Al-Si alloys at the same silicon content. in the other hand, the wear weight loss of Al-Si alloys in the absence of Ni decreased from 2.43 g to 0.36 g with increasing the silicon content in Al-Si alloys, and the weight loss decreased in Al-Si-Ni alloys from 0.77 g to 0.17 g in the presence of Ni as alloying element. The improvement in tensile, hardness and wear testing are attributed to the presence of hard intermetallic phase Al3Ni in the material as observed from XRD and SEM examinations.
