Professor Yuri Estrin
Professor Yuri Estrin is attached to the Department of Materials Engineering at Monash University and is a Professor in Physical Metallurgy.
Currently, Professor Estrin is exploring the development of bulk nanomaterials which are used in structural applications, specifically in surgical implants and micro electromechanical systems (MEMS). Bulk metals are processed by using Severe Plastic Deformation (SPD) methods to produce a material with the grain size in the 100 nanometre range. This results in superior mechanical properties of the product, hazard-free production as the loose nanoparticles are not handled, and a large through-put.
“This is a challenging new area in physical metallurgy, and the possibility to conduct modelling-driven research is of special interest to me. I have been developing models of the deformation processes leading to extreme grain refinement by SPD and these models provide a platform for process optimisation.”
This research coincides with similar studies both nationally and internationally, and is poised on the brink of a major breakthrough in the manufacturing industry.
Like his colleague Dr Lapovok, Professor Estrin is a member of the International NanoSPD group. At Monash, the NanoSPD group benefits from state of the art equipment to produce bulk nanomaterials. His collaboration with the ARC Centre of Excellence for Design in Light Metals allows Professor Estrin to explore the development of new aluminium, magnesium and titanium based materials.
Professor Estrin’s wider interests take him into the field of computational modelling of metallic materials. Using geometry-inspired design principles he is developing new and hybrid elements which may be applied to architecture on the larger scale or as protective layers on the nanometre scale. He is also investigating the impact of nanostructuring on the interaction of metallic materials with living matter.
