“…Today, aluminium alloys are commonly used in numerous industries, predominantly in transport, automotive, aerospace and aviation industries [1][2][3][4][5][6][7][8]. The most important properties of aluminum alloys; in addition to aluminium alloys being plentiful in nature, its facility to produce, machine, and mould, being lightweight and its improvable mechanical properties also increase the place of use and the importance of these alloys even more in today's industries [9][10][11][12].…”

In this study the effect of the change in the amount of Silicon (Si) occuring in Al-Si alloys on mechanical and machinability properties of the alloy was investigated. The change in mechanical properties and microstructure, which depends on the increase in Si percentage, and the effects of this change on Flank Build-up (FBU), wear on the cutting edge, surface roughness, and machinability were also studied. Alloys in different ratios of Si (i.e. 2 to 12 wt %), were employed in the study. The specimens for tests were obtained by casting into metal moulds. The results obtained from experimental studies indicate improved mechanical properties and machinability, depending on the rise in Si percentage in Al-Si alloys. It is also observed that the increase in Si percentage enhanced surface quality.

“…Bu geometrinin aşınma dayanımı üzerindeki büyük avantajından dolayı ötektik üstü alaşımlar piston ve benzeri uygulamalarda da kullanılmaktadırlar [4]. Ancak primer Silisler sayesinde yüksek aşınma direnci sağlanmasına rağmen süneklilik önemli derecede düşmektedir [5]. Bu yüzden Si modifikasyonu üzerine literatürde pek çok çalışma yapılmıştır [6].…”

“…Bu yüzden Si modifikasyonu üzerine literatürde pek çok çalışma yapılmıştır [6]. Primer silisler, alaşım elementi ilave etme, ısıl işlem, ultrasonik titreşim ve soğuma hızı metotları ile modifiye edilebilirler [5]- [8]. Primer silis modifikasyonu aynı zamanda kalan ötektiğin de modifiye olmasını sağlamaktadır.…”

“…Primer silis modifikasyonu aynı zamanda kalan ötektiğin de modifiye olmasını sağlamaktadır. Yanıcı ve çevre kirletici etkilerinden dolayı P modifiye edici olarak pek tercih edilmemekte [5], [7] bunun yerine, son yıllarda primer silis modifiyesinde Sr kullanılmaktadır [9]. Ötektik üstü Al-Si alaşımlarında ince, düzgün geometride ve homojen dağılmış primer ve ötektik Si fazları aşınma özelliklerinin yanında mekanik özellikleri de iyileştirebilmektedir.…”

The phonon and thermodynamic properties of rare-earth-aluminum intermetallics AlRE (RE=Y, Gd, Pr, Yb) with B2-type structure are investigated by performing density functional theory and density functional perturbation theory within the quasiharmonic approximation. The phonon spectra and phonon density of states, including the phonon partial density of states and total density of states, have been discussed. Our results demonstrate that the density of states is mostly composed of Al states at the high frequency. The temperature dependence of various quantities such as the thermal expansions, the heat capacities at constant volume and constant pressure, the isothermal bulk modulus, and the entropy are obtained. The electronic contribution to the specific heat is discussed, and the presented results show that the thermal electronic excitation affecting the thermal properties is inessential.
