The blume-emery-griffiths model on Cayley tree and its phase transitions by Ganikhodjaev, Nasir, Idris, Amin

“…We consider simple version of the Blume-Emery-Griffiths model on the Cayley tree and investigate the problem of phase transition using the exact recursion equations for the Cayley tree of second order, so that every spin has three nearest neighbours. These equations are studied analytical-ly for D>0 and J>0. …”

The potential for suppressing rail defect growth through tailoring rail thermo-mechanical properties by I., David, N., Fletcher, H. Sanusi, Shahmir

“…Thermal damage of rails can occur through brake lock-up, or traction control system failure to prevent wheel spin. In most cases the damage produced is shallow and takes the form of a “white etching layer”, usually thought to have a martensitic structure, formed as the steel is heated above its eutectoid tem-perature and then rapidly cooled as the wheel moves away. …”
