Titanium foams produced by solid-state replication of NaCl powders
Open-celled titanium foams were fabricated by vacuum hot pressing of a blend of Ti and NaCl powders followed by NaCl removal in water. Densification kinetics of the Ti/NaCl blends are measured at 780 ◦C at various pressures (30–50MPa), NaCl volume fractions (30–70%) and NaCl powder sizes (50–500 m). As compared to pure Ti powders, densification kinetics of the blends is faster for relative dens...
متن کاملAluminium Foam and Magnesium Compound Casting Produced by High-Pressure Die Casting
Nowadays, fuel consumption and carbon dioxide emissions are two of the main focal points in vehicle design, promoting the reduction in the weight of vehicles by using lighter materials. The aim of the work is to evaluate the influence of different aluminium foams and injection parameters in order to obtain compound castings with a compromise between the obtained properties and weight by high-pr...

متن کاملBending Stiffness of Aluminium Foams
The basic manufacturing processes of cellular materials have been briefly noted as well as the metal foam properties. The most widely used are the aluminium foams due to the following properties: very good insulation (thermal insulation and sound absorption), low density (mass), high specific rigidity in sandwich structures, very good impact damping, corrosion resistance, non-flammability, very...
متن کاملShape-memory NiTi foams produced by replication of NaCl space-holders.
NiTi foams were created with a structure (32-36% open pores 70-400 microm in size) and mechanical properties (4-25 GPa stiffness, >1000 MPa compressive strength, >42% compressive ductility, and shape-memory strains up to 4%) useful for bone implant applications. A mixture of NiTi and NaCl powders was hot-isostatically pressed at 950 and 1065 degrees C and the NaCl phase was then dissolved in wa...
