DZ40M alloy is a newly developed directionally solidified cobalt-base superalloy. The present work investigated microstructures, room-temperature tensile and stress-rupture properties at 980 degrees C/83 MPa of the alloy in as-cast, solutionized as well as aged states. The microstructure of the DZ40M alloy can be modified by heat treatment. Solution treatment at 1280 degrees C for 4 h dissolved the primary carbides essentially and the alloy became a single-phase supersaturated solid solution… CONTINUE READING
