Dispersion of TiC particles in an in situ aluminum matrix composite by shear plastic flow during high-ratio differential speed rolling

“…This is because (1) TiC particles can be formed directly by the exothermic reaction among TiO 2 , carbon and liquid aluminum [1][2][3][4], (2) TiC particles have sufficient wetting when in contact with aluminum melts, leading to good particle distribution in the melt and development of strong interfaces after solidification [1] and (3) TiC particles have a high elastic modulus and hardness. In the microstructure of an as-cast in situ composite, however, TiC particles are often localized in regions in which many TiC particles are clustered.…”

Low-temperature synthesis of (TiC + Al2O3)/Al alloy composites based on dopant-assisted combustion

“…Examples of the fundamental systems include Al-TiO 2 [10][11][12][13][14][15], Al-Ti(TiO 2 )-B(B 2 O 3 ) [16][17][18], Al-Ti(TiO 2 )-C [19][20][21][22][23][24][25][26], Al-ZrO 2 -B(B 2 O 3 ) [27,28], and Al-ZrO 2 -C [29][30][31]. Of these systems, the Al-TiO 2 -C system is a representative that can be used for the in-situ production of Al alloy composites reinforced M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 4 / 27 with TiC and Al 2 O 3 .…”

In situsynthesis of Fe(Co)/TiC composite by self-propagating high temperature and mechanochemical methods

“…6,11 High ignition temperature in SHS process caused high energy consumption and the grain growth phenomenon. 7,13 Zhang et al reported that addition of Fe to Ti-C reactants significantly promotes the reaction occurrence by the prior formation of FeTi liquid. 7 Razavi and Rahimipour investigated the feasibility of producing Fe-TiC composite from cheaper materials (ilmenite concentrate and carbon black) via mechanical activated sintering.…”

“…Additionally, some literatures have been reported regarding the analysis of the role of Fe content and mechanical activation in the combustion synthesis of Ti–C–Fe powder mixture 6,11. High ignition temperature in SHS process caused high energy consumption and the grain growth phenomenon 7,13. Zhang et al reported that addition of Fe to Ti–C reactants significantly promotes the reaction occurrence by the prior formation of FeTi liquid 7.…”
