||Steel is the most widely used alloy and for a very good reason. The reason is usually considered to be the abundance of iron ore (iron is the principal ingredient in all steels) and/or the ease by which it can be refined from ore. Neither of these is necessarily correct; iron is by no means the most abundant element, and it is not the easiest metal to produce from ore. Steel is such an important material because of its tremendous flexibility in metal working and heat treating to produce a wide variety of mechanical, physical, and chemical properties. Heat treating of steel is the process of heating and cooling of carbon steel to change the steel's physical and mechanical properties without changing the original shape and size. Heat Treating is often associated with increasing the strength of the steel, but it can also be used to alter certain manufacturability objectives such as improve machinability, formability, restore ductility etc. Thus heat treating is a very useful process to help other manufacturing processes and also improve product performance by increasing strength or provides other desirable characteristics. High carbon steels are particularly suitable for heat treatment, since carbon steel respond well to heat treatment and the commercial use of steels exceeds that of any other material.
Heat treating techniques include annealing, case hardening, precipitation strengthening, tempering and quenching. During different heat treating processes, various atmosphere/steel reactions occur at the part surface, and diffusion/phase transformation happens inside the steel part. It will help the heat treaters and heat treating equipment producer to understand the reactions, diffusion and phase transformation process. Many researchers have studied a lot with experimental methods and numerical simulation tools.
This symposium will encourage the experts from heat treating companies and researcher from institutions or universities to communicate and share their new findings. Topics anticipated include, but are not limited to:
• Development of novel heat treatment technologies
• Materials science for heat treatment process design
• Numerical simulation of gas/metal reactions, diffusion and phase transformation during heat treating
• Improvements of heat treatment response through re-designing steel composition
• Microstructural study of steel during heat treatment processes
• Study on the relationship between microstructure and mechanical properties of heat treated steel
