| Abstract Scope |
A high temperature alloy’s efficacy is dependent on understanding its deformation mechanisms across the serviced temperature range. Traditionally, this has required time-intensive creep testing and expensive electron microscopy to determine if mechanisms are controlled by dislocation motion (APB shearing), diffusion (climb bypass), or a combination of both (planar faults) at a given temperature and stress. The present work is a stress relaxation experiment devised to quickly extract the Norton Coefficient as a function of temperature. CMSX3 is extensively characterized with traditional approaches to validate this experimental method. Ultimately, new relationships between stress, temperature, and strain rate are elucidated. This method is shown as a promising approach to testing high temperature alloys in a low-cost, high-throughput way. |
