What is it about?
A new cast Ni-base superalloy was developed. This study predicts the optimum temperature and strain rate range for safe secondary processing (e.g. rolling or forging) of a cast superalloy.

Why is it important?
Secondary processing of cast superalloys is necessary to produce wrought forms. Optimum secondary processing (e.g. rolling or forging) parameters can only produce defect-free wrought products. The present study provides the appropriate temperature and strain rate range for the secondary processing of such cast superalloys.
Perspectives
Hot deformation of compositionally complex superalloys is complex. Simple high-temperature testing and microstructures after deformation and their correlation can give valuable clues to obtain defect-free wrought products.
