NANOSTRUCTURAL PROCESSES OF MELTING AND CRYSTALLIZATION OF CAST IRON
Литьë и металлургия, 2015 It is shown that melt of cast iron of the eutectic structure consist of austenite nanocrystals, graphite, acementite and atoms of iron. Processof melting and crystallization of cast iron is difficult physical and chemical nanoprocess. Thermodynamic it is

Nonclassical Austenite-Martensite Interfaces [PDF]
Le Journal de Physique IV, 1997 In the last 10 years a new theory of martensitic transformations based on nonlinear elasticity has been developed and intensively studied by J.M. Ball & R.D. James and others. Microstructures are understood in the theory as minimizing sequences for the total free energy, and are conveniently described using Young measures. For the case of the classical

Advanced Science, EarlyView.Precipitation‐modulated recrystallization enables a programmable bimodal harmonic architecture in a high‐entropy alloy, delivering 1–2 GPa yield strength with >10% ductility from −196 °C to 700 °C. The resulting broad‐temperature robustness arises from the synergy of dual‐mode nanoprecipitation, harmonic core–shell topology, and temperature‐adaptive ...

Combining gradient structure and TRIP effect to produce austenite stainless steel with high strength and ductility [PDF]
, 2016 We report a design strategy to combine the benefits from both gradient structure and transformation induced plasticity (TRIP). The resultant TRIP-gradient steel takes advantage of both mechanisms, allowing strain hardening to last to a larger plastic ...
