Numerical Calculations of New Innovative Heat Treatment

摘要

When developing new materials and alloys, there exists a technology that has not yet been widely utilized. A specifically designed HIP, equipped with URQ? (Uniform Rapid Quenching) or U~2RC~(TM) (Uniform Ultra Rapid Control) can perform heat treatments that are impossible to do in any other way. It also enables cooling rates of several thousand °C/min. In some cases it can lower the thermal stresses by an order of magnitude or more compared to conventional available heat treatment methods. This paper will present CFD simulations describing the gas flow that surrounds the parts and its impact on how stresses and thermal gradients develop inside components during heat treatments. A comparison will be made of what happens during different types of heat treatments and why. There will also be a discussion of the extraordinary effects that can be achieved with this method.
