Work hardening behavior in a steel with multiple TRIP mechanisms
M. C. McGrath, D. C. Van Aken, N. I. Medvedeva +1
Transformation induced plasticity (TRIP) behavior was studied in steel with composition Fe-0.07C-2.85Si-15.3Mn-2.4Al-0.017N that exhibited two TRIP mechanisms. The initial microstr…
First-principles study of the Mn, Al and C distribution and their effect on the stacking fault energies in austenite
N. I. Medvedeva, M. S. Park, D. C. Van Aken +1
We present ab-initio simulation of manganese, aluminum and carbon impurities in austenite and demonstrate their inhomogeneous distribution, which involves the repulsion of intersti…
Electronic properties of NiCl tubular nanostructures
V. V. Ivanovskaya, A. N. Enyashin, N. I. Medvedeva +1
Atomic models of zigzag (n, 0)- and armchair (n,n)-like NiCl2 nanotubes (n = 4 - 29) formed by rolling (100) single layers of the bulk NiCl2 which crystallizes in the CdCl2-type st…
Band structure of new superconducting AlB_2-like ternary silicides M(Al_{0.5}Si_{0.5})_2 and M(Ga_{0.5}Si_{0.5})_2 (M= Ca, Sr and Ba)
I. R. Shein, N. I. Medvedeva, A. L. Ivanovskii
The electronic band structures of the new superconducting (with T_c up to 7.7K) ternary silicides M(A_{0.5}Si_{0.5})_2 (M= Ca, Sr, Ba; A= Al, Ga) in the AlB_2-type structure have b…
Electronic Properties of TiO Nanotubes
V. V. Ivanovskaya, A. N. Enyashin, N. I. Medvedeva +1
quasi-one-dimensional (1D) titania nanostructures - single-walled nanotubes formed by rolling [101] planes of TiO (anatase phase) are modeled and their electronic properties an…
Effect of metal vacancies on the electronic band structure of hexagonal Nb, Zr and Y diborides
I. R. Shein, K. I. Shein, N. I. Medvedeva +1
Energy band structures of metal-deficient hexagonal diborides MB (M = Nb, Zr and Y) were calculated using the full-potential LMTO method. The metal vacancies change th…
