Because of their inherent low ductility, TiAl-based materials are difficult to fabricate, especially thin gage titanium gamma aluminide (TiAl) sheet and foil. In this paper, an innovative powder metallurgy approach for producing cost-effective thin gage TiAl sheets (with 356 mm long and 235 mm wide, and a thickness of 0.74, 1.09, 1.55, and 2.34 mm, respectively) is presented. The microstructure...

The paper attempts to study the machinability issues of aluminium-silicon carbide (Al-SiC) metal matrix composites (MMC) in turning using HSS cutting tool. SiCp-reinforced metal matrix composites (MMCs) containing SiC particles (5wt%-20wt %) of 400mesh size were prepared by powder metallurgy (P/M) route and used as work material for turning. Experiments were conducted at various cutting speeds ...

Acoustic sonic and ultrasonic resonance analysis is a new non-destructive testing technique that allows 100% testing of a wide range of test objects quickly and at low cost. After an impact, a specimen vibrates in certain characteristic modes and frequencies that can be measured by a microphone or laser vibrometer. Typical faults that can be detected are cracks, cavities, detached layers, mater...
