Production of Fe-TiN and Fe-Ti(N,C) composite powders by mechanical alloying
In this research, the production of Fe-TiN and Fe-Ti(N,C) composite powders by mechanical alloying was investigated and evaluated. Ferrotitanium (containing 70%Ti), titanium and graphite were used as the raw materials. Initial mixtures were milled in different time durations under the pure nitrogen atmosphere with the pressure of 5atm. The results showed that when N2 pressure is 5 at...
متن کاملMechanism of Bainite Transformation in Fe-Cr-Mo-V-Ti-C Steel
The kinetics and mechanism of bainite transformation have been studied in Fe-Cr-Mo-V-Ti-C steel high speed dilatometry backed by thermodynamic analysis. The complete transformation of austenite, however, has not occurred at any reported temperature. Obtained results confirm the incomplete reaction phenomenon with the cessation of the bainite transformation well before the paraequilibrium is ach...
متن کاملHydrogen-vacancy interactions in Fe-C alloys.
Energetics and concentrations of hydrogen-containing point defect clusters (PDCs) in Fe-C alloys are calculated and cast into a PDC dominance diagram. Because of the strong binding effects of iron vacancies on the stability of the clusters, hydrogen accumulation requires the total hydrogen and vacancy concentrations to be comparable. As a result of the interplay between repulsive and attractive...
متن کاملTHE EFFECTS OF C , P , AND S ON TRACE ELEMENT PARTITIONING DURING SOLIDIFICATION IN Fe - Ni
The effect of the minor elements P, S and C on the distribution coefficients of It, Ge, Ga, Au, Cu, and Cr between the solid and liquid phases in Fe-Ni alloys was measured experimentally. Distribution coefficients for It, Ga, and Au increase with increasing P content while the distribution coefficients for It, Ge, and Ni increase with increasing C and S contents. For Ge, the distribution coeffi...
متن کاملInternal Friction in Fe-Co-Ni-Ti Shape Memory Alloys
The anomalies of the temperature dependences of the logarithmic decrement and eigen frequency of the free damped vibrations for Fe-Co-Ni-Ti shape memory alloys were first found in the vicinity of the reverse ay martensitic transformation. It was shown the damping capacity in the alloys investigated is comparable with that for TiNi based alloys.
