摘要：

Inconel 713C as-cast test pieces were produced by investment casting. The tensile properties at 25 and 650 degrees C were obtained along with microstructural and microfractographic characterization. The tensile testing results followed the requirements of the AMS 5391D standard. Additionally, stress-rupture testing at 982 degrees C and 152 MPa, and 815 degrees C and 305 MPa was carried. The aged gamma - gamma ' microstructures were compared and discussed in terms of rafting kinetics. The stress-rupture results followed the AMS 5391D requirements. The relationship between the as-cast and aged microstructures and the mechanical properties was discussed.
