چکیده
Abstract The application of aluminum alloys at elevated temperatures has been attractive for decades, and Al-Ni-based have recently recognized as potential candidates. effect Mn on Al-4Ni alloy investigated in this work. Addition transformed the eutectics from Al 3 Ni/α-Al to 9 (Ni,Mn) 2 /α-Al phases. also improved tensile strength both 25°C 250°C. yield increased 48 MPa 92 with 1.87% then 117 3.77% Mn. At 250°C, 35 82 101 showed less loss than eutectic phase good thermal stability. No coarsening was observed after 2000 h

Effect of Al–5Ti–C Master Alloy on the Microstructure and Mechanical Properties of Hypereutectic Al–20%Si Alloy
Al-5Ti-C master alloy was prepared and used to modify hypereutectic Al-20%Si alloy. The microstructure evolution and mechanical properties of hypereutectic Al-20%Si alloy with Al-5Ti-C master alloy additions (0, 0.4, 0.6, 1.0, 1.6 and 2.0 wt%) were investigated. The results show that, Al-5Ti-C master alloy (0.6 wt%, 10 min) can significantly refine both eutectic and primary Si of hypereutectic ...

15 صفحه اولImproving of Microstructure and Mechanical Properties of Al-A356 Alloy with Compo-Casting Method
Aluminum/alumina composites are used in automotive and aerospace industries due to their low density and good mechanical strength. In this research, the effect of mechanical stirring of slurry in liquid-solid phase temperature and injection of alumina powder with inert gas (Ar) on microstructure and mechanical properties of Al-A356 alloy is investigated. In order to improve of the wettability a...
متن کاملEffect OF SI and AL on the Microstructure, Mechanical Properties and Machinability of 65CU-35ZN Brass
Relations between the microstructure, mechanical properties and machinability of as-cast 65Cu-35Zn brass with various amounts of Al from 0 to 4.72 and Si from 0 to 3.62 wt% were investigated. Both Si and Al initially enhanced the UTS and toughness of the brass samples, which led to improvement in machinability due to a reduction in the main cutting force. A duplex brass with random oriented α p...
