Characterization of Heterostructured Nanocrystalline Metals Processed by High-Pressure Torsion

Creator:: Han, Jae-Kyung
Abstract:: High-pressure torsion (HPT) is an effective severe plastic deformation (SPD) technique to produce bulk nanostructured materials (BNMs). These BNMs often show a combination of exceptional mechanical and physical properties. Processing of single metals and alloys by HPT has been understood that the homogenous microstructures can be achieved throughout the disk...

Refractory Amorphous Metal Thin Films

Creator:: Olsen, Kristopher R.
Abstract:: Amorphous metal thin films lack the grain boundaries and dislocations present in crystalline metal films. As a result, amorphous metal films can be more mechanically robust, atomically smooth, and more resistant to chemical attack than crystalline metals. However, amorphous metals are meta-stable and subject to crystallization upon heating, thus limiting...
