| Abstract Scope |
In this study, 14YWT samples consolidated by either Hot Isostatic Pressing or Hot Extrusion were produced at various temperatures to establish processing-structure-property relations. Microstructure investigation showed significant differences in grain size and structure. HIP processed specimens showed equiaxed grains with a bimodal distribution and increasing average grain size with increasing HIP temperature. The ER specimen showed a bimodal grain distribution with grains elongated in the extrusion direction. The electrical and thermal conductivity for nanostructured 14YWT was measured over a range of temperatures. Electrical resistivity was measured from 3 K to 400 K and thermal conductivity was measured from 300 K to 1275 K. Electrical resistivity proved to be highly sensitive to processing pathway, however thermal conductivity was microstructure independent. Other thermal properties including heat capacity, thermal diffusivity, and thermal expansion coefficient are also reported. |
