Definition

Nickel base materials have outstanding resistance to thermal, mechanical, and corrosive stresses. They include up to 15 elements with a portion of more than 50% in weight and are able to resist long-term stresses up to a homologous temperature, which is the ratio between the temperature load and the melting temperature, of approximately 0.85 (Buergel 2006). Nickel base materials are used in gas turbines, jet engines, space vehicles, and many more modern applications with extreme conditions.

However, due to the outstanding capabilities the material is hard to machine (Donachie and Donachie 2002). To understand the machinability of nickel base materials the following characteristics are essential (Wiemann 2006):

  • Toughness stays stable with the temperature.

  • Strain hardening is common.

  • The structure includes hard and abrasive carbides.

  • Poor heat conductivity leads to high temperatures in the cutting process.

  • Diffusive...
