“…This double constitution of the external oxide scale, which was clearly seen here when the scale remained on the alloy despite the tendency to spallation during cooling, was earlier observed in other oxidized superalloys containing titanium. [34][35][36] Whatever it happened during cooling, collecting the lost oxides and analyzing them with the X-ray diffractometer allowed seeing that TiO 2 was present in the external scale even for the alloys richer in cobalt than in nickel, despite the tendency of the latter ones to lose their outermost part of external oxide by shear rupture. The external TiO 2 layer tended to be thicker for the nickel-richest alloys: this suggests an easier outwards diffusion of titanium, which can be explained by the easy availability of the Ti atoms only present in solid solution in the matrix.…”

This work investigates the possible influence that titanium may have on the oxidation of {nickel and/or cobalt}-based chromium-rich alloys. It starts with the elaboration by casting of a series of alloys from pure elements, with a base element ranging from nickel only to cobalt only. To magnify these possible effects of titanium and reach the atomic equivalence with the carbon present (0.4 wt pct C) in the alloys, 1.6 wt pct Ti was introduced in the chemical composition. To amplify the oxidation process, the oxidation tests carried out in laboratory air were run at the constant temperature of 1200 °C for a rather long time (170 hours). The surface states and cross-sections were characterized by XRD, electron microscopy and EDS analyses. The results demonstrate that all the alloys (except the nickel-free cobalt-based one) resisted oxidation rather well without catastrophic evolution due to titanium. The tested Ti content led to significant internal oxidation and to an external selective oxidation producing a thin layer stick on the outer side of the chromia scale. It is supposed that this outermost TiO 2 layer may be beneficial for the oxidation behavior by the possible limitation of the deleterious over-consumption of chromium by chromia re-oxidation/volatilization. This will be later verified by further investigations combining thermogravimetry follow-up of the oxidation rate and analysis of chromium balance sheets.

“…In MMC, the ceramic particle reinforced metal matrix has good mechanical properties and wear resistance and has been widely studied [5]. Among many particle reinforcements, titanium carbide (TiC) was considered to be a good reinforcement due to its high hardness, high melting point, and relatively high thermal and chemical stability [6][7][8][9][10][11]. There are two methods for prepared the TiC particles reinforced metal matrix by self-propagating high temperature synthesis (SHS) and additive particles.…”

In this paper, TiC particle reinforced high chromium cast iron matrix composites were prepared in situ by casting and infiltration method. The effects of different volume fractions of moderator on the size of reinforced particles, volume fractions of reinforced particles, hardness of composites and abrasive wear were studied. The results show that the TiC particles become smaller and more uniform with the increase of the volume fraction of moderator, and the volume fraction of the enhanced particles also decreases with the increase of the volume fraction of moderator. The hardness of TiC increased by 69%. Abrasive wear tests show that the abrasive wear resistance of the composite with moderator content of 20% is the best, the lowest wear rate can reach 2.011E-008,and the wear resistance is 1.8 times higher than that of the metal matrix.

“…Although MMCs are promising materials for the chemical and process industries, little attention has been paid to their properties owing to their high melting temperature, poor wettability, and density mismatch between the reinforcement and metal matrix [10,17] . Typically, steel matrix composites are reinforced with ceramic particles, such as carbides (titanium carbide (TiC), SiC, WC), borides (TiB 2 ), and oxides (Al 2 O 3 , ZrO 2 ) [18][19][20][21][22][23][24][25][26][27][28][29] . TiC particles can be considered as suitable reinforcements for steel matrix composites owing to their high hardness, low density, good wettability with steel, chemical inertness, and high melting point [23][24][25][26][27][28][29][30] .…”

The high-temperature properties such as the tensile strength, hardness, coefficient of thermal expansion (CTE), and thermal conductivity of titanium carbide (TiC)-reinforced stainless steel (SS) matrix composites fabricated by the infiltration process were investigated at various temperatures. Highly concentrated, closely adjacent TiC particulate reinforcement effectively suppressed dramatic variations in the CTE and thermal conductivity properties originating from the phase transformation of the SS431 matrix with superior mechanical properties. The strengthening effect of the addition of TiC increased as the temperature increased and showed a higher value after the phase transformation. The TiC–SS431 composite showed great applicability for advanced high-temperature-resistant structural materials.
