New approach for modelling strain induced precipitation of Nb(C,N) in HSLA steels during multipass hot deformation in austenite [PDF]

, 2009
A new model for strain induced precipitation of Nb(C,N) is developed from the existing model for single pass hot deformation. This new model can be extended to multipass deformation to explain the microstructural evolution during the hot deformation of ...

Electron-lattice kinetics of metals heated by ultrashort laser pulses [PDF]

, 1999
We propose a kinetic model of transient nonequilibrium phenomena in metals exposed to ultrashort laser pulses when heated electrons affect the lattice through direct electron-phonon interaction.
