Effect of Ageing on Microstructure, Mechanical Properties

2020/08/12· A study on the mechanical property changes and the creep behavior of a Ni-based alloy 740H on ageing at 800 °C for 10250 hours is conducted. Microstructural characterization reveals that the alloy initially contains fine γ′ phase and carbide precipitates within grains and at grain boundaries. Ageing does not affect the grain size but coarsens the γ′ phase and facilitates further
