摘要
To homogenize Ti-Hastelloy-N, the segregated MC-type carbide stringers must be dissolved during solution annealing and enough time allowed for the carbide forming elements to diffuse uniformly throughout the matrix. A solubility product-l/Τplot and simple diffusion equation were used to estimate the parameters for a successful homogenization treatment. Compared to the material which contained stringers, the homogenized material had: 1) greater postirradiation ductility with significantly reduced scatter in values and 2) better resistance to intergranular cracking caused by tellurium vapor at 1033 K. The basic principles used to develop the homogenization treatment are applicable to other Ti or Nb stabilized alloys. © 1979 American Society For Metals And The Metallurgical Society of AIME.
