Abstract

Lattice parameter of TaC‒TaB2 balk prepared by mechanochemical and spark plasma sintering (SPS) was investigated by Nelson ‒ Riley method.In this study, TaC‒B4C powder milled at 3, 6, 9, 12 hours and sintered by spark plasma sintering (SPS).Lattice parameter and C/Ta ratio of TaC‒TaB2 was calculate by Nelson–Riley method and storm relation. In this research TaC‒B4C powder was reacted and produced TaC‒TaB2 composite. Phase formation and powder morphology during milling and sintering were examined using different analysis techniques including XRD,FE-SEM. Lattice parameter of the powders was increased by milling time and sintering temperature. Ill.7. Ref. 19. Tab. 3.
