Evolution of Hierarchical Microsxtructures in Additive Manufacture Metallic Materials and its role on mechanical Properties 

Presented By: Amir Hadadzadeh, University of Memphis



The demand for lighter, stronger and more sustainable materials for advanced applications resulted in the development of cutting-edge materials in recent years. Additive manufacturing (AM) as a breakthrough for the fabrication of near-net shaped components, plays a revolutionary role in the evolution of advanced materials with enhanced properties. Selective laser melting (SLM), is among the most commonly used AM processes. Ultrafine, metastable, and hierarchical microstructures are developed in SLM materials due to very high solidification rates. Consequently, enhanced mechanical properties are often achieved for these materials.

Developing cutting-edge AM metals and alloys (e.g. aluminum, steels, stainless steels, and titanium) with superior mechanical properties requires comprehensive knowledge on how to tailor the hierarchical microstructure to enhance the strengthening mechanisms at different length scales. Such knowledge is developed through multi-scale characterization of the microstructure of AM materials using sophisticated techniques.

The results of these studies pave the pathway to developing the fundamental knowledge on processing-microstructure-prosperities relationship in AM materials to develop the next generation of advanced, strategic and novel materials.


Dr. Amir Hadadzadeh is currently an Assistant Professor at the Department of Mechanical Engineering, University of Memphis (UofM). His research is in the field of additive manufacturing of metallic materials, processing-microstructure-properties relationship in advanced metals and alloys, multi-scale characterization of microstructure and texture of metals and alloys, and microstructural evolution and strengthening mechanisms in AM materials. He received his PhD in the field of Mechanical Engineering from the University of Waterloo, Canada

Participation is mandatory for all MIME graduate students
