Writing By Reza Haghayeghi :
I am a well-trained metallurgist who has an extensive experience in the field processing metallurgy particularly Solidification and Casting. As an inquisitive and enthusiastic person, I am interested to work on the research area of Materials Engineering and it’s the related phenomena to improve the scientific understanding of this subject of science.
Assistant Professor Reza Haghayeghi after accomplishing his Master Degree in Iran initiated his Doctoral study at Brunel University (UK) in 2006 under Technology strategy Board fund (~£2.1) where several companies were involved in. After obtaining his PhD, he joined Science and Research Branch of Azad University of Tehran in 2010 as an assistant professor. Further, Reza Haghayeghi pursued his study (Post-Doctoral) at University of Campinas (Brazil) by a fund which was provided by United Nation (UN) in 2015. This prestigious award is only granted to 10 people across the world where Assistant Professor Reza Haghayeghi was one of them. He is currently working at Science and Research Branch of Azad University and is currently known as potential and key reviewer for many peer-reviewed Journals. Membership of several research groups including AAAS, Iranian Foundrymen’s society and American Association for Science and technology and so forth.
In his previous studies, he investigated grain refinement by intensive shearing at above liquidus temperature. Further, the nucleation phenomenon via HRTEM in-situ observation at above liquidus temperature was examined. Indeed, he has vast experiences on application of external forces on grain refinement of alloys such as exerting electromagnetic field, ultrasonic treatment with particular focus on microstructural evolution.
As a summary his main research interest are: Solidification Science (solidification-kinetics, convection effects on solidification processes (nucleation and growth kinetics, interface stability). Applying novel experimental and casting techniques including electromagnetic stirring, ultrasonic (cavitation, shock force and acoustic streaming technologies), mechanical shearing, etc., for understanding and control of various microscopic and macroscopic phenomena that take place during the solidification of alloys including microstructure evolution, interface instability of alloys, hot tearing, shrinkage and porosities. Other research interests include dynamical evolution of microstructures in the presence of external forces with particular focus on segregation and elements diffusion at non-equilibrium situations in materials systems under extreme conditions. He has also utilize the Artificial Neural Networks (ANN), and computational fluid dynamics (CFD) for process understanding, modelling and optimization
He has also worked with various companies including Novelis, Alacn. Luxer, Honda and BP. Furthermore, he has taught various academic courses including Solidification, Solidification in Welding, Casting, Fracture mechanics (Fatigue, Creep, Crack analysis) and Crystallography with great expertise in SEM, ESEM, XRD and so forth. He has also supervised under-Grads and Post-Grad students and have evaluated their theses.
