| Abstract Scope |
This talk discusses processing-structure-property relationships in gradient Ti-based alloys. Multiple gradient approaches are adopted, including the use of composition and thermal gradients. This talk will describe two key components of gradient materials. Firstly, the importance of modeling and validation with experimental measurements. A case study is given regarding the modeling associated with the processing of a Ti-xW based alloy. Given the differences in the thermophysical properties across the Ti-xW binary space, it is necessary to predict processing conditions to successfully process arbitrary compositions along the gradient. Secondly, advances in the manufacture of Ti-based gradients are presented. The talk will discuss using thermal gradients to engineer microstructural gradients, and will extend observations into topologically complex shapes with spatially varying properties. In addition, we will discuss the opportunity to rapidly understand the structure-property relationships by simultaneously varying both thermal and compositional gradients as two orthogonal axes within a single specimen. |
