Effect of strain rate on the tensile behavior of a single crystal nickel-base superalloy
The effect of various strain rates on the tensile behavior of a single crystal nickel-base superalloy was studied. Single crystals with 〈0 0 1〉 crystal orientation were tested at 800 and 1000 °C under three kinds of strain rate of 10 −3, 10 −4 and 6 × 10 −5 s −1. The yield strength increased with th...

−1. The yield strength increased with the increase of strain rate, while the configuration of the stress–strain curves was independent of strain rate. Additionally, fracture surface was related to strain rate at two temperatures. At 800
°C the amount of cleavage surface was different at three strain rates, which resulted from the difference of activated slip systems. The elongation increased with the decrease of strain rate, which was influenced by the heterogeneous ductile deformation. At 1000
°C the difference of fracture surface was attributed to the microvoid at higher strain rate, while the γ/γ′ interfaces also played an important role at lower strain rate; elongation rate was independent of strain rate. |
