Choice of thermal treatments for ferrous materials for the automobile

Drawing up a guide to choosing heat treatments for ferrous metals in the automotive sector is a tricky business for several reasons:

• firstly, because there isn't just one technical solution to a function, but often several competing ones;

• secondly, because choices often depend on the industrial context (existing resources, investment policy, flow management, environmental problems, etc.);

• lastly, because the specifications for a function or component change very quickly, as do the range of technical solutions on offer.

We'll start with a fairly thorough overview of the automotive context, covering the vehicle entity, its main mechanical components, their functional requirements, and finally the industrial context.

In the second part, this approach will enable us to look at solutions in terms of technologies and functional properties, compare processes and discuss trends for the near future.
