Systematic Temperature Control when Turning Metastable Austenitic Steels (B02)

• Subject Area: Metal-Cutting and Abrasive Manufacturing Engineering
• Term: from 2011 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 172116086

Aim of the project is the increase of fatigue strength and wear resistance of highly stressed components by near surface phase transition. For that purpose, selected metastable chrome nickel steels are machined applying carbon dioxide cooling. Low temperatures in the cutting zone are necessary to accomplish a deformation induced transition from metastable austenite into martensite via mechanical interaction between tool and work piece. To optimize the cooling a transient simulation of the temperature field in the work piece is utilized.
