Tensile Properties of a Low-cost First Generation Single Crystal Superalloy DD16
The tensile properties of a low-cost first generation single crystal superalloy DD16 have been investigated.The results show that values of the tensile strength and yield strength of DD16 alloy were similar at typical temperatures; from room temperature to 760℃,the yield strength of DD16 alloy increases; However,above 760℃,the yield strength of DD16 alloy decreases remarkably,and the maximum of the yield strength was 1145.5MPa at 760℃.From room temperature to 760℃,the fracture mode was cleavage fracture; But above 760℃,the fracture characteristics changed from cleavage to dimple.
