Abstract
Tensile fracture behavior of a single crystal nickel-based superalloy under different orientations and temperatures was studied. The tensile fracture surfaces were analyzed by scanning electron microscope. The results showed that, generally, this single crystal nickel-based superalloy exhibited obvious tensile anisotropy. Under the condition of room temperature, the different areas of crack nucleation, propagation and final fracture area were clearly observed and varied greatly in different orientations. The fracture surface presented mixed characteristics of holes and dimples at high temperature and its fracture was dominated by micro-void coalescence.
