The chemical analysis performed on the powder material (36-h milling) showed the presence of elements such as silicon (Si), potassium (K), aluminum (Al), titanium (Ti), iron (Fe), and oxygen (O) (Figure 8). The final milling was performed in a 36-h time; however, a stop of the process was made at 18 h to take a sample. It has been found that carbon addition improves the mechanical properties of titanium and its alloys due to the presence of titanium carbide particles, which restricts the growth and formation of phase precipitates. During the experimental process, three initial millings were made: two wet millings and one vacuum dry milling, in order to fine-tune the process parameters. titanium-carbide powder. TiC composites exhibited the best properties with hardness value (97HRB) and compression strength value (275Mpa). Experimental process details of powder grinding. From the initial millings, it was determined that the milling time had to be longer, in order to obtain higher concentrations of titanium carbide in the milling; this milling was named final milling.
