The 2nd InternationalSymposium organised by HTM-21 Project, NIMS
May 31(Thursday)- June 2(Saturday), 2001This Symposium covers Ni-base superalloys and possible alternative materials beyond superalloys for ultra-high temperature use, including coatings, for aeroengines, gas turbines, etc. Materials design and development, process, structure/property analysis and evaluation, materials/system interface, applications of the materials, etc. are all dealt with.
No registration is needed in advance, but just on site. Free of charge to attend the Symposium, except for the Reception.
An abstracts book is available at the Symposium. The proceeding papers will be published later on in a special issue of "Materials Science and Engineering A" after a pure review.
