Sponsored Research Projects

Pratt & Whitney: High-temperature-stable Ti/Fe welded joints Aug. 2012 – Aug. 2013

Advised by Dr. Glenn Daehn, The Ohio State University, Columbus, OH

Identified Nb and Cu as effective barriers to prevent interdiffusion at Ti/Fe welded junctions

Created Ti/Fe welded joints which remained stable against the formation of intermetallic compounds through a 24-hour heat treatment at 910 C (1670 F)

Optimized welding parameters for the Ti/Nb/Cu/Fe four-layer system

U.S. Department of Energy: Solid-state welding of dissimilar metals Aug. 2013 – Aug. 2016

Advised by Dr. Glenn Daehn, The Ohio State University, Columbus, OH

Realized welding of “unweldable” combinations of dissimilar structural alloys, e.g. Al/Fe

Identified 8 strongly impact-weldable dissimilar metal pairs out of 18 candidates tested

Achieved >80% strength retention for 5 Al/Fe weld combinations through a 30-day-long warm salt-spray corrosion test, by means of suitable protective coating

Miniaturized spot welds by 50% while maintaining mechanical performance

Re-designed a key welding consumable and standardized its manufacturing process, resulting in improved performance, repeatability, and economy
