The recipient of 2017 Lee Hsun Lecture Series—Lee Hsun Lecture Award, Prof. Nobuhiro Tsuji from Department of Materials Science and Engineering at Kyoto University visited Institute of Metal Research, Chinese Academy of Sciences (IMR, CAS) from April 24 to 28, 2018.

During the visit, Prof. Tsuji delivered a lecture entitled “Bulk　Nanostructured　Metals　processing,　structure　evolution,　and　mechanical　properties”. In his lecture, he introduced their recent research progress in obtaining fully-recrystallized nanostructures with mean grain sizes much smaller. Such materials show both high strength and enough strain-hardening ability leading to large uniform elongation.

Prof. Tsuji has been studying physical metallurgy and mechanical metallurgy of structural metallic materials involving both steels and nonferrous alloys. His research works cover metal working processes, heat treatments, recrystallization, phase transformation, metallography, microstructures, textures, crystallography, electron microscopy, dislocation theory, and mechanical properties of metallic materials.

Especially, he has developed accumulative roll bonding (ARB) process, which is a kind of severe plastic deformation (SPD) process using rolling deformation for fabricating ultra fine grained or nano structured bulky materials, and has energetically studied the ultrafine grained and nanostructured metals fabricated by ARB and other processes.

Prof. Tsuji has published many papers about the correlation between microstructures and mechanical properties of nano structured materials, which have been highly cited. He has received many scientific awards including the 5th JSPS Prize.
