The shape memory effect and the synthetic midge

Event details

Nitinol is a remarkable material which has the ability to ''remember'' two different macroscopic shapes and flip between them when heated and cooled. I will discuss the microscopic behaviour responsible for this in terms of crystal geometry, and twinning deformation, and how this can be modelled at a continuum level in much the same way as phase separation behaviour. Further I will discuss how essentially the same effect induced by magnetism could be used to make microscopic flying machines without the need for microscopic engines.

About Condensed Matter lunchtime seminars

This is a weekly series of informal talks given primarily by members of the institute of condensed matter and complex systems, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
