Research interests:

• Additive Manufacturing
• Crystal Plasticity
• Microstructure and Mechanical Properties

Summary of work:

The additive manufacturing (AM) techniques are developed to fabricate alloys by sintering and/or melting metal powders layer by layer. The AM processes allow to obtain materials with certain crystallographic texture, which significantly influence properties of a material. However, the better understanding of heat transfer during the AM process is required to make the manufacturing technique more efficient. The goal of my research is to study the melting and solidification processes and its’ impact on material texture.
