Thermodynamic assessment of liquid Fe-Ni-C alloy using modified quasichemical model

Paek, Min-Kyu; Jeon, Junmo; Paliwal, Manas; Biswas, Arijit; Lindberg, Daniel; Pak, Jong-Jin (Springer, 2020-11)

The liquid solution properties in the Fe-Ni and Fe-Ni-C systems have been thermodynamically assessed using the modified quasichemical model in the pair approximation. The asymmetry of the Fe-Ni and Fe-Ni-C alloy melts was ...
The role of crystallographic texture on mechanically induced grain boundary migration

Renk, O; Ghosh, Pradipta; Sabat, R. K.; Eckert, J.; Pippan, R. (Elsevier, 2020-11)

Mechanically induced migration of grain boundaries and triple junctions not only determines the size and shape of nanostructures created by severe plastic deformation, it substantially affects their mechanical properties ...
Plastic strain triggers structural instabilities upon cyclic loading in ultrafine-grained nickel

Kapp, M. W; Renk, O.; Ghosh, Pradipta; Leitner, T.; Yang, B.; Pippan, R. (Elsevier, 2020-11)

Grain growth accompanied by shear band formation shortens lifetime of nanostructured metals upon cyclic loading. Although the occurrence of structural instabilities was reported frequently, the difficulty to detect and ...
Methanol electrolysis for hydrogen production using polymer electrolyte membrane: a mini-review

Pethaiah, Sethu Sundar; Sadasivuni, Kishor Kumar; Jayakumar, Arunkumar; Ponnamma, Deepalekshmi; Tiwary, Chandra Sekhar; Sasikumar, Gangadharan (MDPI, 2020-11)

Hydrogen (H2) has attained significant benefits as an energy carrier due to its gross calorific value (GCV) and inherently clean operation. Thus, hydrogen as a fuel can lead to global sustainability. Conventional H2 ...
Intrinsic electronic defect states of anatase using density functional theory

Raghav, Abhishek; Tri Hanindriyo, Adie; Utimula, Keishu; Abbasnejad, Mohaddeseh; Maezono, Ryo; Panda, Emila (Elsevier, 2020-11)

In this work an overall electronic structure including the position and formation energies of various intrinsic defects are computed for anatase using Density Functional Theory aided by Hubbard correction (DFT + U). The ...
