Development of Al-TiC Alloys Using Powder Metallurgy as Grain Refiners for Aluminium and Its Alloys

2013
Al-Ti-C master alloys have been widely investigated for many years as grain refiner for aluminium and its alloys. In this work, the Al-Ti-C master alloys are synthesized using powder metallurgy technique through the mixing of aluminium and TiC powders with different TiC contents 3.75 (3), 5(4), 6.25(5) and 7.5(6) Wt% TiC(Wt% Ti).

Effect of extrusion ratio on the grain refinement and properties of copper prepared by powder metallurgy route

The present study emphasizes determining the optimum value of the extrusion ratio for superior microstructure and mechanical properties of copper via the synergistic effect of powder metallurgy and extrusion process. In this study, sintered Cu is hot extruded for different extrusion ratios, from 2.8 to 11.1.
