3D experiments shed new light on shape memory alloys

Posted on Mines Newsroom at http://www.minesnewsroom.com/news/researchers-elucidating-unknown-shape-memory-alloys Check out the recognition of our shape memory work in the March 2019 issue of Science!  Shape memory alloys are well known for their remarkable properties —superelasticity, shape memory and actuation allow them to be crumpled up and then spring back to a “remembered” original shape. But the advanced material remains […]

Breakthrough research performed by Ashley Bucsek

Ashley Bucsek, BeamTeam PhD candidate, performed the first-ever dark-field X-ray diffraction measurements on shape memory alloys at the European Synchrotron Radiation Facility (ESRF) in Grenoble, France. The video clips below show that she was able to capture subgrain microstructure features, including dislocations nucleating from carbide interfaces. The “Rocking at high temp” video above shows the sample being rocked at high […]
