Jianxiong Li

Jianxiong Li came to The Ohio State University in 2017 to pursue a doctorate in welding engineering. The China native earned his undergraduate and Master's degrees in welding engineering from Tianjin University in 2014 and 2017, respectively.

Li credits his interest in the process-microstructure-property relationship and physics of materials with guiding him to the welding engineering discipline. Since arriving at Ohio State, he has been a Graduate Research Assistant in Dr. Glenn Daehn's Impulse Manufacturing Laboratory, which focuses on the development of novel manufacturing solutions using impulse-based processes. 

I have a particular affinity for impulse welding, especially vaporizing foil actuator welding (VFAW), which was invented by Dr. Daehn at Ohio State. VFAW creates a high-strength, fatigue-resistant metallurgical joint between a NiTi shape memory alloy and dissimilar metals like stainless steel, brass and titanium.

Li narrowed his welding engineering concentration to VFAW of NiTi shape memory alloys and adding Lincoln Electric Professor Boyd Panton as his primary advisor. Part of his research helps define material behaviors of metals subjected to vaporizing foil actuator welding versus traditional joining processes known to change materials' fundamental properties. Li describes, "using VFAW, we generate amorphous phases under impact between two crystalline alloys, NiTi and stainless steel. This is explained by rapid cooling and frustrated crystallization in a multi-component melt".  

A select group of graduate students has the honor of being named Presidential Fellows. The competitive application program awards winners financial support, allowing them to complete their dissertations or projects with less of a financial burden.

“The Presidential Fellowship provides me with the support necessary to complete my doctoral degree and launch me to the next stage of my career. It is an absolute honor to be awarded the highest scholarly recognition by the Graduate School at Ohio State.” 

Upon completing his doctoral studies at Ohio State, Jianxiong Li plans to continue researching as a research scholar or professor and focus on dissimilar metal welding and processing in a national lab or university. 

The Department of Materials Science and Engineering congratulates Jianxiong Li for being awarded Ohio State's most prestigious honor.
