Pressing and Infiltration of Metal Matrix Nanocomposites
The ability to produce metal matrix nanocomposites via pressing and infiltration was validated. Al/TiC nanocomposite was used as the model material. Pressing the powder in a die yielded cylindrical specimens with a green density of 1.98 ± 0.05 g/cm<sup>3</sup>, which was increased to onl...
