Purpose and goal

The goal of the project is the development of a concept and underlying methodology (ready for transfer) for achievement of improved machinability of certain metallic materials via designed micro-alloying which promotes protection of a cutting tool against wear without the use non-metallic inclusions. Another goal is to demonstrate the concept for a minimum of one material from each of the following groups: manganese steels, stainless steels (Ni-alloys), and ultra-clean steels.

Expected results and effects

The two following main results are: 1) Knowledge and understanding of the concept for improved machinability via controllable build-up of tool protection layer by designed micro-alloying of the workpiece material. 2) Methodology for implementation of the proposed concept as a complete and transferable instrument for R&D activities for multiple players in the value chain. These results will allow for development of clean and ultra-clean steels and alloys which have better mechanical or functional properties, and which maintain the desired machinability.

Planned approach and implementation

The achievement of the project goals is relying on the work structure consisting of 7 workpackages and collaboration among 4 academic and 6 industrial partners. The concept of controlled and continuous in-situ formation of a protective layer on the tool, as a result of tool material reaction with micro-alloying elements is tested experimentally in WP1 and WP3 while simultaneously evaluated with thermodynamic WP2 and diffusional WP5 studies. Obtained results are then transferred onto selected demonstration material cases WP4, validated in WP6 and converted into methodology in WP7.
