Structural transformations in Li2MnSiO4: evidence that a Li intercalation material can reversibly cycle through a disordered phase

Li2MnSiO4 is a promising high capacity cathode material due to the potential to extract two Li ions per formula unit. In practice, however, the use of Li2MnSiO4 is restricted by a low discharge capacity, which has been attributed to an irreversible structural change in the first charge cycle. In this work, we use density functional theory calculations to explore the details of this structural c...

Adiabatic phase transformations in confinement

The phase diagram of small one-component particles has been analyzed under conditions of thermal insulation, i.e., conservation of energy. In large isolated systems the absolute stability belongs to heterogeneous states with phase separation. However, for small particles the global stability analysis shows a considerable extension of the single-phase regions into a two-phase zone of the phase d...

Some phase transformations in steels

About 70% of all the steel compositions that are currently used have been developed within the last 10 years. Novel iron alloys are being conceived, manufactured, and marketed with a regularity which has confounded many prophecies. Phase transformation theory has contributed to the successful development of steels. This overview will begin therefore with a discussion of the atomic mechanism by ...
