Microstructure and Mechanical Property Evaluation of Aluminum F357 Powder for Cold Spray Applications

Effects of Friction Stir Process Parameters on Microstructure and Mechanical properties of Aluminum Powder Metallurgy Parts

The effects of friction stir processing (FSP) on the microstructure and mechanical properties of aluminum powder metallurgy (PM) parts was investigated. PM parts were then subjected to FSP at advancing speeds (v) of 40-200 mm/min and tool rotational speeds (ω) of 800-1600 rpm. Microhardness (HV) and tensile tests at room temperature were used to evaluate the mechanical properties of the frictio...

Powder Stream Characteristics in Cold Spray Nozzles

The exponential increase of industrial demand in the past two decades has led scientists to the development of alternative technologies for the fast manufacturing of engineering components, aside from standard and time consuming techniques such as casting or forging. Cold Spray (CS) is a newly developed manufacturing technique, based upon the deposition of metal powder on a substrate due to hig...

Process Development & Microstructure & Mechanical Property Evaluation of a Dual Microstructure Heat Treated Advanced Nickel Disc Alloy

This paper summarises Rolls-Royce’s efforts in developing a production capable and industrially robust process for the production of dual-microstructure components. This has been possible through the use of process modeling, full-scale validation trials, detailed microstructural assessment through a variety of destructive and non-destructive methods and mechanical property evaluation. This pape...

Mechanical milling of aluminum powder using planetary ball milling process

Mechanical alloying has recently attracted considerable attention as researchers strive to enhance nanocomposite properties and extend their utility. The process can be performed at room temperature and homogeneous nanocomposite powders can be produced. In this paper, we investigated the effect of different ball milling parameters and operating conditions (milling time, ball size, processing co...
