Research
My research in materials engineering begins with a fundamental quest: to unravel the intricate interplay of microstructures across varying length scales and how these interactions give rise to diverse material properties. These properties encompass crucial aspects like strength, impact resistance, fatigue durability, abrasion resistance, electrical conductivity, and resistance to corrosion. To grasp the essence of these material properties, it becomes imperative to dissect and isolate distinct phenomena. While we primarily rely on commercially available equipment for our investigations, there are instances when we must devise our own methodologies to probe the mechanical attributes of materials.
The mechanical characteristics are intricately tied to the microstructural composition and the various stages of the manufacturing process. Our ultimate objective is to fathom the profound influence of microstructure on the mechanical traits of diverse materials, enabling us to predict and engineer materials with superior attributes compared to their predecessors.
In our pursuit to characterize microstructures, we employ a wide array of cutting-edge microscopy techniques, including light optical and scanning electron microscopes, as well as advanced methods like X-ray diffraction and synchrotron light-based approaches. As an ongoing example, we are currently exploring the impact of different surface treatment techniques on the fatigue properties of mechanically developed powdered materials.
