A356/SiCP composites were prepared by stir-casting and were foamed immediately using titanium hydride. The compression properties (compressive strength, plateau stress, and absorbed energy) of foams increase with the increase in relative density (RD)

Composites of Al-Si-Mg (A356) alloy with silicon carbide particles were synthesized in-house and foamed by melt processing using titanium hydride as foaming agent. The effects of the SiCP size and content, and foaming temperature on the stability and

Aluminium foams are of interest due to their ultra low density, high structural stiffness per unit weight. Like conventional Al foams having Ca, ceramic particle (e.g. SiC, Al2O3) containing Al alloy metal matrix composite (MMC) foams can be produced

A commercial Al–Si–Mg composite was diluted to different SiC (mean size: 8 µm) contents, and was foamed using TiH2 by melt based technique at a fixed foaming temperature. Foams with high expansions were achieved and uniform cell morphology is ob

A simple method of metal foam production is to introduce a blowing agent (e.g. TiH2) into an aluminium melt containing foam stabilisers such as oxides (usually Ca-based) and/or particles (e.g. SiC, Al2O3). In this work, Al/SiC composites (in-house an

Metallic foams find specialised applications in industry due to their unique properties such as ultra light weight and high impact energy absorption. When ceramic particles (e.g. SiC, Al2O3) are present, metal matrix composite (MMC) foams can be fabr

Among cellular metals, aluminium foams are the most commonly produced, and provide a unique combination of properties such as: very low density, high energy absorption under static and dynamic compressions, blast amelioration, sound absorption, and f

Al–Si–Mg/SiCP foams were prepared by melt processing route with TiH2 as the blowing agent. The effects of foaming temperature (640 and 670 °C), SiCP size (12 and 21 μm), and volume % (5–20) on liquid foam expansion and subsequent collapse wer

The crystallization and mechanical behavior of a hafnium-containing bulk amorphous alloy (Hf28.35Zr28.35Cu15.3Ni12.5Nb5.0Al10.0Y0.5) was investigated and compared with a Hf-free alloy (Zr56.7Cu15.3Ni12.5Nb5.0Al10.0Y0.5) to understand the role of hafn
