Tensile Deformation Behavior of a Directionally Solidified Superalloy in the Range from Cryogenic Temperature to High Temperature | Chapter 5 | Recent Progress in Science and Technology Vol. 5

 The pliable deformation performance of directionally solidified superalloy DZ406 was investigated at cryogenic hotnesses from -125∘C to 25∘C, and the comparative reasoning of room temperature and 1000∘C was completed activity. The yield strength and fundamental strength at cryogenic temperatures were nearly that at room hotness, and twice that at 1000∘C. The extension was maintained at 10–15% and exhibited the plasticity at cryogenic hotnesses. At cryogenic temperatures, the fracture samples basically showed no kissing phenomenon, and the cracks primarily happen in the MC carbide itself in the interdendritic areas. At range temperature and 1000∘C, nevertheless, the fracture surface was covered in dimples that held carbides. At cryogenic temperatures and range temperature, slip bands and dislocations both provided to the tensile deformity; however, at 1000∘C, only the dislocations were active.
