Amirian, B., Li, H.Y., Hogan, James D.
In this paper, a microstructure-based finite element model for nano-grained (!+↵2)-TiAl/Al2O3 cermets is proposed based on a modified variational formulation of the Gurson model for an elastic-plastic porous material. In the modeling approach, the high volume fraction of alumina, variability in...

Li, Haoyang, Motamedi, Pouyan, Hogan, James D.
This study investigated the rate-dependent mechanical properties and failure of a self-propagating high-temperature synthesized TiAl/Ti3Al-Al2O3 cermet using mechanical testing and advanced microscopy. Quasi-static and dynamic uniaxial compression tests coupled with high-speed imaging and digital...
