Impact response of Al2O3 and Al2O3-TiB2 ceramic composites

A new high-temperature, oxidation-resistant in situ TiB and TiC reinforced Ti6242 alloy

“…Usually, the weight gain in titanium alloys is described by a rate equation of the form [7] w n = k p t (1) where w is the weight gain per unit initial area, k p the oxidation rate constant, n the rate exponent, and t is the time. The oxidation rate constant, k p , at each temperature was calculated from the slope of the plot of the weight gain per unit initial surface area versus the square of annealing time.…”

“…Titanium matrix composites (TMCs) are attractive structural materials for applications in the field of aviation, aerospace and automobile because of their high specific modulus, high specific strength, and high strength at elevated temperature [1,2]. However, their industrial applications have been limited by the poor high-temperature oxidation resistance.…”

Microstructure and mechanical property of in situ synthesized multiple-reinforced (TiB+TiC+La2O3)/Ti composites

“…[1,2]. The mechanical properties of titanium matrix composites are controlled by both the reinforcements' characteristics and the bonding features of the reinforcement-matrix interfaces [3].…”

Observation of weakened and strengthened creep behavior in Ti/TiB(w) composites at high temperatures

“…The creep behavior of metal matrix composites strengthened by dispersing discontinuous reinforcements has become a topic of considerable interest, primarily because these materials have potential for use in structural applications at high temperatures [1,2]. Strengthening mechanisms by reinforcements during steady-state creep have been explained by two concepts.…”
