Speech Title: A Novel Approach to Rapidly Evaluate Creep Behavior of Superalloys by a High-Throughput Compression Creep Testing
Abstract: High-throughput experimental technology has drastically transformed the landscape of material development by substantially reducing both the development time and associated costs. This is particularly evident in development of new materials for aeroengines. Creep behaviour is one of the key mechanical properties for performance of aeroengines, especially the blades. Tensile creep testing was the traditional method to evaluate creep behaviour, but this is both time-consuming and expensive. This study introduces a novel approach of a high throughput compression creep test, which facilitates simultaneous testing of eight samples, thus significantly reduces the time and cost compared to traditional methods. This novel testing method has been successfully employed for rapidly screening creep properties during development of new materials and offers the capability to screen roles of chemical composition for engineering materials. In addition, this study has also successfully utilized the compression creep data to establish a quantitative correlation with tensile creep data, leading to accurate predictions of stress rupture life very quickly. Thus, the high throughput compression creep technique represents a significant advance in the field, offering a novel technique for the rapid evaluation of high-temperature performance of superalloys.
