Prof.
Shi Changxu is regarded as a pioneer in the
field of supper-alloys in . He led the development
of the first generation of cast hollow turbine
blades. Shi presided over the creation of
a national science and technology development
planning for the country concerning metallurgical
material, material science, and other new
materials. He has served as a researcher and
honorary director of the and was a specially

Fund Committee. He was also vice-president
of the China Academy of Engineering and was
elected as an academician to that academy
in 1994. The following year in 1995, he became
an academician of the Third World Academy
of Science.

Prof.
Zhuang-Qi Hu, born in Shanghai on 31 Aug.
1929, graduated in the Department of Chemistry,
University of Shanghai in 1952, professor
of the Institute of Metal Research, Academia
Sinica and academician of the Chinese Academy
of Engineering. He is also a member of the
Asian Pacific Academy of Materials. He was
a visiting scientist in MIT, head of the Department
of Superalloys and Special Casting, director
of the State Key Laboratory of Rapidly Solidified
Nonequilibrium Alloys and chairman of the
Academic Committee of the Institute of Metal
Research, Academia Sinica.
Prof. Hu is now the
editor-in-chief of the Journal of Materials
Science and Technology, board member of the
Chinese Society of Materials Research. He
is honorary professor of Northeast University
and concurrent professor of nine famous universities
in China.
He is emphasized to
study the nonequilibrium solidification, directional
solidification under lateral constraint and
rapid solidification processings, solute redistribution
and phase precipitation, heat flow and solute
trapping during rapid solidification, and
develop new materials with novel properties,
including superalloys, directionally solidified
and single crystals, intermetallic compounds
and nonequilibrium alloys.
He is one of the leaders
in high temperature new materials research
field in our country. He got 14 awards for
his significant achievements in science and
technology. for example ¡°Development of air
cooled blades for jet engine¡± ?first prize
of National Award of Scientific and Technological
Progress, ¡°Ultrasonic atomization process

Technological Progress, ¡°Formation, microstructure
and properties of nanostructured materials¡±
¨Cthird prize of National Award of Natural
Science, etc. He wrote and translated a total
of ten books and published 473 papers in foreign
journals and 452 papers in Chinese periodicals.
He has cultivated 78 doctors and 22 graduate
students for master degree, as well as 16
postdoctors. He won the title of Liaoning
provincial model worker and provincial outstanding
scientist having achievements in science and
technology.

Prof.Wang
Zhongguang, a specialist on fatigue of materials,
was born in April, 1936, in Wenzhou, Zhejiang
Province, China. He majored in metallic materials
and graduated from the Department of Mechanical
Engineering, Tsinghua University in 1959.
And then he joined the Institute of Metal
Research(IMR), Chinese Academy of Sciences(CAS).
He is now a full professor and Ph. D. academic
advisor of IMR. He is currently a board member
of the Shenyang National Laboratory for Materials
Science and Chairman of Fatigue Society under
the Materials Research Society of China(C-MRS).
He is also a member of the International Committee
of Fatigue. In the years of 1999-2002, he
was appointed the associate editor of the
international journals Acta Materialia and
Scripta Materialia. He is now an editorial
advisory board member of the International
Journal of Fatigue as well as the editorial
board member of the Chinese journals ¡°Acta
Metallurgica Sinica¡± and ¡°Journal of Aeronautical
Materials¡±.
Professor Wang Zhongguang
has mainly devoted himself to the basic research
on fatigue of materials. He investigated the
basic processes in aluminum and its alloys
under fatigue loading by measuring the energy
dissipation. He found that the localization
of deformation taking place in the specimen
resulted in an extra energy dissipation. He
established the experimental relationship
between fatigue crack propagation threshold
and fractal dimension of the fracture surface.
This result provided a clear evidence for
the nonuniversal nature of roughness index
of the fracture surface. Since the middle
of 90¡és, he and his co-worker systematically
investigated the effects of crystallographic
orientation and grain boundary on cyclic deformation
and fatigue damage by using double, multiple
slip oriented copper single crystals as well
as copper bicrystals and tricrystals. Cooperated
with others, he also investigated the fatigue
behavior and mechanisms of rotor steels, stainless
steels, dual-phase steels, metal matrix composites
and intermetallic compounds. He has authored
or co-authored over 200 SCI papers and received
numerous academic awards, including one third-class
and one fourth-class national prize in natural
science, five second-class CAS prizes in natural
science and one second-class natural science
prize awarded by Liaoning Province. He is
also the awardee of the HLHL foundation prize
for scientific and technological progress.
The State Key Laboratory
for Fatigue and Fracture of Materials led
by him during the years of 1988-1997 was highly
ranked in three national evaluations and awarded
with a Golden Ox Medal. Professor Wang Zhongguang
was a member of the International Committee
of Strength of Materials from 1991 to 2000.
He was also the co-chairman of the 7th International
Congress on Fatigue and the co-chairman of
the 2nd International Symposium on Designing,
Processing and Properties of Advanced Engineering
Materials.
Professor Wang Zhongguang
has supervised 26 master degree students and
23 Ph. D. students since 1984, five of them
received the CAS President Prizes for excellent
students. The thesis of one Ph.D. student
of him was selected as one of the 100 excellent
Ph. D. thesises in 2000 in China after a nation-wide
evaluation. He himself was awarded by the
Chinese Academy of Sciences with the title
of ¡°Excellent Academic Advisor¡± in 1990,
1993 and 1996, respectively. |
