Abstract
The mechanical alloying (MA) process has been probed to be an effective method to conveniently develop materials with novel structures. The products of MA can be processed by conventional powder metallurgy routes for further consolidation. However, the novel features conferred to the powders, such as fine crystal size and chemical homogeneity can be lost during sintering operations, due to the high chemical activity of some of the synthesized phases. The Spark Plasma Sintering (SPS) process is an alternative route to obtain highly dense MA′ed products while retaining these novel microstructures, including a metastable state. Advantages of the SPS process over conventional sintering processes are the fast heating and cooling rates, and the high pressure applied. Combining these two material processing techniques (MA and SPS) it is possible to obtain materials with interesting (far from equilibrium) microstructures. Co-Ti alloys were obtained by MA and SPS, as described in related publications.
