Effect of a long-term prior aging on the tensile behaviour of a high-performance single crystal superalloy
1993
Journal de Physique IV : Proceedings
Preserved Fulltext
The influence of long-term aging heat treatments on the tensile behaviour of <001> single crystals of the MC2 nickel-based superalloy was investigated at room temperature, 650 and 950°C. The precipitation of brittle particles of a W-rich 1 phase did not induce any deleterious effect on the tensile strength and ductility. The decrease in yield strength and the increase in ductility were attributed to the coarsening of they ' strengthening particles which promotes by-passing of the precipitates
