This experimental study investigated the effects of quenching and tempering heat treatment on fatigue behavior and also tempering temperature and time holding of AISI 1060 steel. At first, the specimens were austenitized at 800˚C for 1 hour, and then were quenched in the water bath of 25˚C temperature. After that, tempering process was done at the temperature of 250˚C, 450˚C and 650˚C for 1 and...

Highly variable flux surface averaged heat fluxes are resolved in gyrokinetic simulations of ion temperature gradient ITG turbulence, even in large systems. Radially propagating fronts or avalanches are also seen. Their propagation lengths in gyroradii and relative amplitude remain constant as simulation size is increased, so the avalanches appear to result from local dynamics, rather than glob...

In this note we investigate propagation of smallness properties for solutions to heat equations. We consider spectral projector estimates the Laplace operator with Dirichlet or Neumann boundary conditions on a Riemanian manifold without boundary. show that using new approach Logunov and Malinnikova (2018) allows one extend type Jerison Lebeau (1999) from localisation open sets localization arbi...

Heat propagation in the Guyer–Krumhansl model is studied. The exact analytical solutions for the one-dimensional Guyer–Krumhansl equation are obtained. The operational formalism is employed. Some examples of initial functions are considered, modeling various initial heat pulses and distributions. The effect of the ballistic heat transfer in an over–diffusive regime is elucidated. The behavior o...
