Dr Reza Taherzadeh Mousavian
Postdoctoral Researcher

Dr Taherzadeh is a postdoctoral researcher in metallurgy based in DCU. He completed his PhD on the manufacturing of aluminium matrix nanocomposites reinforced by well-dispersed ceramic nanoparticles via casting, followed by enrolling in the Faculty of Materials Engineering in Sahand University of Technology in 2016. His undergraduate degree was in the area of porous ceramic matrix composites fabrication via thermal explosion from Shahid Bahonar University of Kerman. His main research interests are in microstructure and mechanical properties of multi‐component alloys and strength-ductility trade-off in metals and alloys.

Research Interests (Lay Summary)

Since joining I-Form in 2018, Dr Taherzadeh has been working on laser surface treatment of Zr-based bulk metallic glasses with a focus on HRTEM and nano-indentation studies on heat-affected zones during laser processing to improve plasticity via dispersion of nano ZrCu crystals in an amorphous matrix.

Dr Taherzadeh has also been involved in atomic scale simulation of TWIP-TRIP high-entropy alloys. A focus area for his I-Form research is the investigation of additive manufacturing processes using TWIP-TRIP high-Mn steels. Such steels have extensive applications in automobile industry.

 

Technical Summary

Controlling the microstructure for metals and alloys during high-rate solidification in selective laser melting is both critical and challenging with respect to the trade-off between strength and stress of the additively manufactured component. The desirable outcome is to control and adjust the solidified microstructure without any requirement for thermomechanical post-printing processes. Also, the additive manufacturing process conditions have a strong impact on the plastic deformation mechanism of multi-component alloys. These challenges are being investigated and addressed through our research.
