What about the machinability of future turbomachinery alloys and how to improve it?

Challenge and Motivation

  • Future engine programs require higher heat resistant materials for turbine components.
  • Lack of process knowledge regarding cutting of new materials superior IN718 (like e.g. Rene 65, AD730, γ-TiAl).


  • Evaluation of machinability criteria.
  • Derivation of recommendations for machining of the investigated “future material”.
