Abstract:

Elastocaloric cooling, in which substantial temperature variations in materials respond to an application and removal of a mechanical field, is the latest discovered type in solid-state caloric cooling. In the first section of this talk, I will present a composite magneto-elastocaloric effect with an ultra-low magnetic field (0.16 T) in a compact geometry to generate a cooling temperature change as large as 4 K using a magnetostriction/superelastic alloy composite. In the second section, I will show our progress on exploring unique properties of elastocaloric alloys by use of laser directed-energy-deposition, a powder-fed additive manufacturing technique in collaboration with Ames laboratory. 

Brief CV of Dr. Huilong Hou: 

Huilong Hou is a postdoctoral research associate in the Department of Materials Science and Engineering at the University of Maryland.  He received his Ph.D. in Engineering Science and Mechanics from the Pennsylvania State University in 2015.  His current research focuses on exploring and tailoring shape memory alloys for elastocaloric cooling and implementing advanced fabrication techniques for thin films and bulk materials.  He is a member of The Minerals, Metals & Materials Society (TMS) and American Vacuum Society (AVS).
