Effects of electric current on solid state phase transformations in metals
TL;DR: In this article, the influence of an electric current on the following solid state transformations in metals are considered: (1) intermetallic compound formation and growth in diffusion couples, (2) precipitation, (3) crystallization of amorphous alloys and (4) recrystallization and grain growth of cold worked metals.

Mechanical Properties and Retained Austenite in Intercritically Heat-Treated Bainite-Transformed Steel and Their Variation with Si and Mn Additions
TL;DR: In this paper, process peculiarities and functions of alloying elements, such as Si and Mn, were studied for improving formability of steel sheets with mixed microstructures, and the holding time in the bainite transformation range varies with temperature, depending on the activation energy of C diffusion in austenite, and shifts to longer times with an increase of Si or Mn additions.

On the thermodynamics and kinetics of electropulsing induced dissolution of β-Mg17Al12 phase in an aged Mg–9Al–1Zn alloy
TL;DR: In this article, a model for the temperature field of a strip under EPT was established based on the contributions of the coupling of the thermal and athermal effects with the free energy and the direct electron-atom interactions, the thermodynamics and kinetics of the electropulsing induced dissolution of β -Mg 17 Al 12 are discussed.

Effect of phosphorus on the formation of retained austenite and mechanical properties in Si-containing low-carbon steel sheet
TL;DR: In this paper, the effect of phosphorus and silicon on the formation of retained austenite has been investigated in a low-carbon steel cold rolled, intercritically annealed, and isothermally held in a temperature range of bainitic transformation followed by air cooling.

Formation of Annealing Twins During Grain Growth
R. L. Fullman,J. C. Fisher +1 more
TL;DR: In this article, it is proposed that annealing twins form during grain growth as a result of a decrease in the interfacial free energy of grain boundaries that would not be achieved in the absence of twinning.

An evaluation of the contributions of skin, pinch and heating effects to the electroplastic effect in titatnium
K. Okazaki,M. Kagawa,Hans Conrad +2 more
TL;DR: In this article, the stress drop in the initial elastic region of the stress-strain curve and the Joule heating derived from the current-time profile and a reasonable heat transfer coefficient were calculated and found to be about 50-70% of the total stress drops associated with these temperature rises.

A study of the electroplastic effect in metals
K. Okazaki,M. Kagawa,Hans Conrad +2 more
TL;DR: In this article, the effects of high density, direct current pulses (100 to 1000 A/sq. mm for periods of 55-120 microsecs) on the flow stress determined in an Instron tensile testing machine were studied in a number of polycrystalline metals representing various crystal structures.
