in this investigation, continuous cooling transformations and microstructures have been studied in detail in a low carbon ti-nb bearing microalloyed steel by means of dilatometry, metallography and hardness measurements. the results indicate that when the cooling rate is greater than 1˚c/s, the dilatation curve is associated with a major dilatation at relatively low transformation temperatures,...
In this work, a 3D thermo-microstructural model was developed to simulate the continuous cooling of steel. The model was employed for simulation of cooling process of the gears made from a plain carbon steel (AISI 1045) and a low alloy steel (AISI 4140). Temperature-dependent heat transfer coefficients for two different quenching media were evaluated by experimental and computational methods. ...
in this paper, we are going to improve the energy efficiency of an industrial c 3 mr base load lng plant by changing its refrigerant components and its mole fractions in liquefaction and subcooling cycles based on the cooling curves generated in the main liquefaction and subcooling heat exchangers. later on, selection features of the elements will be discussed. first, non-optimized c 3 mr plant...
Polystyrene-block-polyisoprene forms micelles in supercritical and subcritical propane upon cooling and decompression. These micelles decompose upon heating and compression. At constant polymer concentration, the micellization points, both isobaric and isothermal, fall around a decreasing boundary curve in pressuretemperature coordinates. This micellization boundary curve lies above the copolym...
We discuss the afterglow emission from a relativistic jet that is initially in the radiative regime in which the accelerated electrons are fast cooling. We note that such a “semiradiative” jet decelerates faster than an adiabatic jet does. We also take into account the effect of strong inverse-Compton scattering on the cooling frequency in the synchrotron component and therefore on the light cu...
