Description
| - Nickel super-alloys are widely used in aerospace as material for turbine blades. Casting can no longer meet the requirements for precision, hence, the castings are being ground or milled. In this contribution, a quality check of the milled surface by several surface integrity parameters is proposed with respect to the surface structural inhomogeneities caused by mutual effect of plastic deformations and thermal fields during the cutting process. Unsuitably chosen machining parameters lay grounds for cracks’ generation, growth and significantly reduced components’ lifetime. Surface integrity was described by macroscopic residual stresses, microstrains, grain sizes and phase composition. Mostly, favourable compressive surface residual stresses were observed in the cutting direction, grain sizes were distinctively smaller when the tool axis was perpendicular to the machined surface. During machining no precipitation of the detrimental σ phase took place.
