MICROSTRUCTURE VARIATION EFFECTS ON ROOM TEMPERATURE FATIGUE THRESHOLDS AND CRACK PROPAGATION IN UDIMET 720Li Ni-BASE SUPERALLOY
An assessment of the effects of microstructure on room temperature fatigue threshold and crack propagation behaviour has been carried out on microstructural variants of U720Li, i.e. as-received U720Li, U720Li-LG (large grain variant) and U720Li-LP (large intragranular coherent γ′ variant). Fatigue tests were carried out at room temperature using a 20Hz sinusoidal cycling waveform at an Rratio=0...
متن کاملLattice strain evolution and load partitioning during creep of a Ni-based superalloy single crystal with rafted microstructure
In-situ neutron diffraction measurements were performed on monocrystalline samples of the Ni-based superalloy CMSX-4 during N-type g0 raft formation under the tensile creep conditions of 1150 C/ 100 MPa, and subsequently on a rafted sample under the low temperature/high stress creep conditions of 715 C/825 MPa. During 1150 C/100 MPa creep, the g0 volume fraction decreased from ~70% to ~50%, the...

متن کاملEvolution of the Annealing Twin Density during -Supersolvus Grain Growth in the Nickel-Based Superalloy InconelTM 718
Grain growth experiments were performed on InconelTM 718 to investigate the possible correlation of the annealing twin density with grain size and with annealing temperature. Those experiments were conducted at different temperatures in the supersolvus domain and under such conditions that only capillarity forces were involved in the grain boundary migration process. In the investigated range, ...
متن کاملEffect of Heat Treatment Process on Microstructure and Fatigue Behavior of a Nickel-Base Superalloy
The study of fatigue behaviors for nickel-base superalloys is very significant because fatigue damage results in serious consequences. In this paper, two kinds of heat treatment procedures (Pro.I and Pro.II) were taken to investigate the effect of heat treatment on microstructures and fatigue behaviors of a nickel-base superalloy. Fatigue behaviors were studied through total strain controlled m...
