摘要	The effects of Re on the tensile and stress-rupture properties and fracture behaviour of a single crystal superalloy containing Re were studied. Tensile specimens were prepared from this single-crystal with [001] orientation. The fractograph was examined by means of scanning electron microscope. The test specimens had the [001] growth direction parallel to the loading axis in tension. The results of the present investigation indicate that the tensile elongation of single crystal superalloy significantly decreased, but the stress-rupture elongation at high temperature increased with Re addition. The fractograph of fracture surface for the tensile specimen at room temperature showed a slide fracturing mode. The fractograph at elevated temperature showed a creep rupture mode with uneven deformation. The fractograph of fracture surface for the stress rupture specimen showed a typically ductile fracturing mode and the deformation was even.
