The effects of Si addition on microstructures, high temperature compressive properties and creep properties of the β-stabilized Ti-45Al-3Fe-2Mo alloy have been studied in this work. The results show that the Si addition decreases the volume fraction of β phase and precipitates particulate Ti5Si3 phase. At the same time, the Si addition improves the high temperature strength of the Ti-45Al-3Fe-2Mo alloy for about 200 MPa at 800°C and decreases the creep strain for about 35% at 800°C under an applied stress of 150 MPa. The decrease in volume fraction of β phase and precipitation of Ti5Si3 particles are believed to be the dominant mechanisms for the improvement of the high temperature properties of the Si-doped TiAl alloy. © 2016 The Japan Institute of Metals and Materials.

Titanium matrix composites reinforced with TiB whiskers were in situ synthesized by spark plasma sintering (SPS) at a temperature range of 11731473 K, using a mixture of 6.2 mass% TiB2, 4.1 mass% Ti, and 89.7 mass% Ti6Al4V powders. The in-situ synthesis mechanism and the effect of sintering temperature on the sintering microstructure were investigated. The results show that an increase of the sintering temperature causes the relative densities of the composites to increase and the reaction between Ti and TiB2 to be more complete. Nano-sized TiB reinforcements with a diameter of around 80 nm and fine-grained matrix with an average grain size of 12μm are obtained after SPSed at 1373 K. Clean and perfect TiB/matrix interfaces without debonding or cracks are obtained during SPS process. Low sintering temperature and short sintering time are believed to be the main reasons for the improved fine-grained microstructure. © 2015 The Japan Institute of Metals and Materials. Source

Deformation behavior of the P/M pure titanium was studied in a temperature range of 400~700 ℃ and a strain rate range of 0.001~1 s-1. A constitutive equation was derived with arrhenius hyperbolic sine function and a processing map was constructed. The results show that arrhenius hyperbolic sine function can well describe the constitutive equation of the powder metallurgy (P/M) pure titanium. The activation energy is 221.23 kJ/mol. The material shows unstable flow when strain rate is higher than 0.1 s-1, and the best processing regions are 450~550 ℃/0.001~0.01 s-1 and 625~700 ℃/0.001~0.01 s-1. ©, 2015, Central South University.
