Sheng Guo

Docent at Chalmers, Industrial and Materials Science, Materials and manufacture

Sheng Guo is currently an Associate Professor at the Department of Materials and Manufacturing Technology, Chalmers University of Technology. Sheng joined Chalmers as an Assistant Professor in 2013. His main research areas are the alloy design and physical metallurgy of concentrated multi-component alloys, better known as high-entropy alloys (HEAs). HEAs have great potential to be used as high-temperature materials, and in environments where high hardness, high wear resistance, and high corrosion resistance are required. Sheng's research interest also goes to other advanced metallic materials, like metallic glasses or amorphous alloys.
