MICROSTRUCTURAL CHARACTERIZATION
In this Work we describe the microstructural effect of the conventional sintering in the mechanical properties of a Ni based alloy synthesized by mechanical alloying (MA). Raw materials were commercial cobalt, chromium and nickel pure powders supplied by Sigma-Aldrich. Compositions studied were Ni60Co30Al10, Ni55Co35Al10, Ni60Co10Cr20Al10 and Ni55Co15Cr20Al10 in at. %. MA was performed using in a SPEX 8000 mill. An argon atmosphere was used to avoid oxidation and methanol was employed as the control agent process. Powders mixtures were milled for 5 and 20 h. Their morphology was analyzed using a JEOL JSM-5800 scanning electron microscopy. Variations in chemical composition were followed by EDS. Microhardness assessments in sintering samples was performed using Vickers scale, 10 indentation were done and the average value was reported. Results are discussed as a function of composition and milling time.
