This paper reviewed several recent progresses of the new powder metallurgy technology known as flake (FPM) including different processing routes, conventional FPM (C-FPM), slurry blending (SB), shift-speed ball milling (SSBM), and high-shear pre-dispersion SSBM (HSPD/SSBM). The name was derived from use metal powders obtained by low-speed (LSBM) spherical powder. In this case, uniformity reinfo...

This study was performed to establish a convenient mouse model for the evaluation of nickel allergy. For sensitization, 0.2 g of nickel sulfate in petrolatum was applied 4 times every other day to the shaved dorsal skin. Seven days after the first application of the nickel sulfate salt sample, the antigen-specific metal allergy reaction was estimated based on the swelling response of the footpa...

Aluminum-based metal matrix composite (MMC) materials are used in the design of ground transportation vehicles and aircraft. Compared with conventional, unreinforced alloys, composite materials usually exhibit higher strength, both at ambient and elevated temperatures, as well as good fatigue strength and wear resistance. MMCs could be produced by variety of methods such as Stir cast, Liquid In...

A powder metallurgy route to the fabrication of metallic glass foam is introduced. The method involves consolidating metallic glass powder blended with blowing agent particulates to produce expandable precursors, capable of yielding foams with porosities as high as 86%. The foams are found to inherit the strength of the parent metallic glass, and to be able to deform heavily toward full densifi...
