High temperature creep in a 〈001〉 single crystal nickel-base superalloy

Microstructure and creep behavior of DMS4-type nickel based superalloy single crystals with orientations near 〈001〉 and 〈011〉

“…9(c) suggest that the amount of creep strain recorded for the alloy at a given time fraction of creep life (t/t r ) is almost identical, irrespective of the applied stress. Similar obser- vations have been reported earlier [30][31][32] for other popular and commercial Ni-based superalloys, CMSX-2 and CMSX-4. The significance of plots shown in Fig.…”

An Investigation Into the Mechanics of Single Crystal Turbine Blades With a View Towards Enhancing Gas Turbine Efficiency

“…The material parameters, in general, are functions of temperature. Simulation was carried out at three di®erent temperatures at various stress values and the results are compared with the experimental results for CMSX-4 ( [69] and [21]). Moreover, it can be observed that the fraction of energy stored decreases at higher temperatures.…”

Relation between the microstructure and microchemistry in Ni‐based superalloy

“…The material has been submitted to creep tests, and the results have been reported elsewhere. [10][11][12] In the present work, the samples crept at 900 C under a stress of 220 MPa have been examined.…”

“…The nominal composition of the CM186LC alloy is the following: Co 9.3, Cr 6.1, Mo 0.51, Al 5.7, Ti 0.73, Ta 3.4, W 8.4, Re 2.9, B 0.016, Hf 1.4, Zr 0.004, Fe 0.027, C 0.062 and Ni to balance (wt%). The material has been submitted to creep tests, and the results have been reported elsewhere . In the present work, the samples crept at 900 °C under a stress of 220 MPa have been examined.…”
