Abstract Scope |
Ring-rolling has proven notoriously difficult to model, control and optimise accurately. We have studied a multi-objective optimisation involving (1) process parameters, (2) geometrical design, and (3) alloy design for manufacturability of a newly developed M647 gamma-prime strengthened C&W nickel superalloy suitable for aero-engine turbine disk. Accurate computational models based on accurate experimentation which allow for knowledge-based choice of the manufacturing variables, built to mitigate the occurrence of excessive adiabatic heating and crack nucleation sites, represent an important step towards the sought-after optimised ring-rolling manufacturability. The results indicate a major improvement of ring-rolling manufacturability by cutting more than 80 percent of processing time whilst maintaining crack-free condition.
