Abstract:
In this work, the precipitates in Ti−Mo−V steel were systematically characterized by high-resolution transmission electron microscopy (HRTEM). The thermodynamics and kinetics of precipitates in Ti−Mo and Ti−Mo−V steels were theoretically analyzed, and the effect of vanadium on the precipitation behavior was clarified. The results showed that the precipitation volume fraction of the Ti−Mo−V steel was significantly higher than that of Ti−Mo steel. The randomly dispersed precipitation and interphase precipitation (Ti, Mo, V)C particles coexisted in the Ti−Mo−V steel. When the temperature was high

Abstract:
AbstractThe characteristics of large precipitates in H13 tool steel with 0.015wt% Ti were studied. The result shows that three types of phases larger than 1 μm exist in the as-cast ingot, that is, (Ti, V) (C, N) type phase, (V, Mo, Cr)C type phase and sulfide. (Ti, V) (C, N) type phase could be further classified as the homogeneous Ti-rich one and the Ti-V-rich one in which Ti/V ratio gradually changes. (V, Mo, Cr)C type phase contains the V-rich one and the Mo-Cr-rich one. The compositional characteristics in all of them have little relation with the cutting position or cooling rate. The prec

Phase formation was studied for Ni/Ti/Si and Ni/TiSi2 structures processed by vacuum RTP. Intermetallic compounds Ni3Ti and Ti2Ni form sequentially above 425 °C for metal bilayers Ni/Ti on Si, as Ni diffuses into Ti. When the temperature reaches 550 °C, Si becomes mobile and diffuses into the Ni–Ti compound, resulting in the growth of a ternary phase Ti4Ni4Si7, (V phase). If Ni is in excess with respect to this ternary silicide, a separate layer of Ni silicide grows between the substrate and the V phase, due to the fact that Ni is the main diffusing species.

Abstract:
The effect of forging process on microstructure and performance of V-Ti, V-Nb-Ti non-quenched and tempered microalloying steel was investigated in this study. By comparing the characteristics between V-Ti and V-Nb-Ti microalloyed non-quenched and tempered steels by the forging process,the machinsm of micro-alloy technology and forging process for dynamic recrystallization and microstructure refinement was investigated. It revealed that addition of Nb in micro-alloying steel can increase significantly non-recrystallization temperature during forging process, and enhance the V (C, N) precipitati

The electrical properties of Ti/Au contacts to anatase TiO2 nanocrystal films are investigated under different thermal annealing temperature (300–500 °C) in a N2 ambient. The as-deposited contact shows a non-linear current–voltage (I – V) property. However, after being annealed at 300 °C and 400 °C, the samples exhibit nearly ohmic I – V behaviors with currents at 5 V bias higher than that of as-deposited one by about three and seven times, respectively. When the annealing temperature is increased to 500 °C, the ohmic contact transform to Schottky contact. The influence of annealing temperatur
