The automobile industry uses magnesium for load-bearing components due to its low density, durability, and ductility. This study investigated a nanocomposite containing Nb2O5 (3 6 wt%) nanoparticles as reinforcement with AZ31 alloy made by stir casting. A severe plastic deformation was conducted on the cast samples via equal-channel angular pressing (ECAP) after homogenization at 410 °C 24 h ag...

Ti6Al4V-TiC metal matrix composite (MMC) coatings were cold sprayed using spherical and irregular Ti6Al4V powders manufactured with plasma gas atomization the Armstrong process, respectively. Composite deposited showed higher ceramic retentions lower porosity compared to powder (SP) coatings. Sliding wear tests performed at two different normal loads a WC-Co ball as counterface. Wear test resul...

Infiltrated particle reinforced composites combine a dense matrix with particles that are in mutual contact and can therefore transfer compressive stress directly from one particle to the next. As a result, these composites may combine characteristics of the plasticity of their matrix with those of granular matter plasticity. We measure here the influence of a 200 MPa superimposed fluid hydrost...

William G. Fahrenholtz o 9m Ceramic Engineering Department ‘so University of Missouri-Rolls w~!!l Rolls, MO 65409 + <. +# Metal-reinforced Alz03-matrix composites were prepared using reactive hot pressing. The volume fraction of the reinforcing phase was controlled by the stoichiometry of the particular displacement reaction used. Dense Alz03-Ni and Al@3-N’b composites were fabricated using thi...

The thermal expansion behaviour of silicon carbide (SCS-2) fibre reinforced 6061 aluminium matrix composite subjected to the influenced thermal mechanical cycling (TMC) process were investigated. The thermal stress has important effect on the longitudinal thermal expansion coefficient of the composites. The present paper used experimental data of the thermal expansion behaviour of a SiC/Al comp...
