Kaiyang Zeng

Kaiyang Zeng is a Doctoral student and Researcher at KTH Royal Institute of Technology, working in the Hultgren Laboratory. His research is part of the EU and Tillväxtverket-funded sustainability project "Green Steel for a Fossil-free Future," addressing critical hydrogen-related challenges in steel production for a fossil-free economy.

His educational background includes an MSc in Nanotechnology from KTH Royal Institute of Technology, Sweden, and a BSc in Materials Science and Engineering from Harbin Institute of Technology, China. This foundation supports his specialized work in advanced materials characterization.

Research focuses on hydrogen's dual role in Fe-Cr-Ni-based austenitic stainless steel, examining both strengthening and embrittlement mechanisms. Using atom probe tomography (APT), he characterizes hydrogen distribution to understand microstructure-property relationships. This work directly informs steel design strategies for hydrogen infrastructure resilience, bridging fundamental materials science with industrial sustainability goals.

As a doctoral researcher, Zeng contributes to the "Green Steel for a Fossil-free Future" project without formal advisees. His work operates under significant EU and Swedish government funding, targeting hydrogen embrittlement solutions essential for decarbonizing the steel industry.

He is embedded in the Hultgren Laboratory, leveraging advanced facilities for atomic-scale materials analysis. The lab's expertise in metallurgy and characterization techniques provides critical infrastructure for his hydrogen-steel interaction studies.
