Symposium Thermodynamics and Kinetics of Alloys IV
Presentation Title Thermal Gradient-Driven Grain Growth in Metallic Alloys
Author(s) Xizheng Wang
On-Site Speaker (Planned) Xizheng Wang
Abstract Scope Understanding and controlling grain growth in metallic alloys requires careful consideration of both thermodynamic driving forces and kinetic limitations. In this presentation, we explore a new approach for studying grain size evolution through spatially controlled thermal gradients applied during sintering. By establishing a continuous temperature differential across metallic samples, we create a gradient in microstructure that enables localized investigation of grain growth behavior under varying thermal conditions. This setup provides a unique platform for examining how spatial temperature gradient affects grain boundary mobility, growth kinetics, and resulting mechanical properties. Our study highlights the potential of thermal gradient engineering not only as a fabrication method for functionally graded materials, but also as a model system to explore classic theories of grain growth and deformation mechanisms. The insights gained offer opportunities to design alloy systems with tailored microstructures optimized for complex service environments.
