Objective

The nature and the morphology of the microstructures control obviously the mechanical properties of steels especially for HSS and BH steels. The microstructures are usually obtained changing the temperature, the chemical composition and plastic deformation before phase transformations and recrystallisation.

A complementary fully innovative approach to microstructure control is proposed here. Applied stress is considered as a new driving force for metallurgical evolutions.

Indeed stress effects afford many promising opportunities:
- slow down phase transformation for compression like state,
- accelerate phase transformation for tension like state,
- change the nucleation and so exhibit an impact on structure size (refinement),
- provide a specific spatial orientation (texture).
