Processing effects on the ductility of chromium-vanadium alloys

Creator:: Murdock, Hailey M.
Abstract:: The next generation of high temperature structural alloys must exhibit exceptional resistance to fracture, creep, oxidation, and fatigue at high temperatures. Chromium is being considered due to its high melting point (>1800°C), relatively low density (~7.2 g/cc), high temperature strength, and oxidation resistance. Limiting the use of chromium is its...

Significance of Grain Refinement on High Entropy Alloys Processed through High-Pressure Torsion

Creator:: Wenrui, Zhao
Abstract:: High entropy alloys (HEAs) are well known for their excellent mechanical properties compared to conventional metallic alloys. The application of High-Pressure Torsion (HPT) processing reduces grain size of materials away below 1 µm. This significant grain refinement leads to an improvement in mechanical properties, such as strength and ductility. In...

Synthesis and Characterization of an Ultrafine-Grained Aluminum-Copper System through High-Pressure Torsion

Creator:: Liang, Guangyuan
Abstract:: Aluminum and copper and their alloys have been widely used due to relatively high strength-to-weight ratios compared with conventional steels. Processing of these alloys is typically conducted at high temperatures over extended time periods. High-pressure torsion (HPT) is a promising processing technique for introducing significant grain refinement leading to excellent...

Development of an adventitious shoot regeneration system in cherries

Creator:: Meneghelli, Luigi P.
Abstract:: Shoot regeneration in vitro is a difficult problem for cherry species. This study addressed three approaches to the problem, regeneration of adventitious shoots from roots and leaves of mature cherry clones, and from cotyledons of open-pollinated 'Royal Ann' cotyledons. Regeneration on roots occurred at a very low frequency. Adventitious shoots...
