Foreword
The Second International Conference on Texture and
Anisotropy of Polycrystals, ITAP-2, was held in Metz,
France, from July 7 - 9, 2004, following the intentions
and guidelines of ITAP-1 in Clausthal 1997.
Interest in texture studies in materials science - both
from a practical and a theoretical point of view - has
many reasons. First of all, texture is one of the
fundamental parameters, in addition to crystal structure,
lattice defects and element composition, to characterize
solid state materials since nature strongly prefers the
crystalline state to the amorphous state, and textured
materials to single crystals as well as to polycrystals
with random distribution of grain orientations. This is
true for natural matter such as minerals, rocks, soil,
wood and bone in the same way as for man-made materials as
for instance metals, semi-conductors, ceramics and partly
crystalline polymers. It is often quite difficult, indeed,
to either produce a single crystal or a completely random
sample. Texture changes are indicative of solid state
processes of all kind; hence texture can be utilized to
advantage as a fingerprint of proper use or misuse of a
work-piece in failure analysis. Texture enables the
geologist to shed light on the processes of rock forming
which took place in early days of the history of Earth.
The knowledge of texture is a prerequisite for all
quantitative techniques of materials characterization
which are based on the interpretation of diffraction peak
intensities such as the determination of the content of
residual austenite in steel, the determination of residual
stress by X-ray diffraction, and structure analysis from
powder diffraction patterns. Most important, however, is
texture as the link between anisotropic properties of
single crystals and those of polycrystalline material.
Noticeable advancements in experimental as well as in
theoretical methods of texture analysis have been made
during the years since ITAP-1. It was the purpose of the
second conference, now held in Metz, to provide a survey
on the state of the art in texture analysis as well as to
discuss some typical applications. Nearly 110
contributions have been presented during 11 parallel
sessions in oral form or as posters. This proceedings
volume contains 74 papers which cover almost all aspects
of texture research. In a few cases the authors preferred
to fuse their presentations at the conference in one
comprehensive paper. The proceedings volume thus may serve
as a guide to this challenging field of science.
An Honorary Colloquium on the occasion of the 75th
anniversary of Hans-Joachim Bunge was celebrated on the
opening day of the conference with a series of plenary
lectures followed by a jolly birthday party in the
evening.
When the proceedings were almost ready for print,
Hans-Joachim Bunge's unexpected sudden decease has cast a
shadow of deep sadness over this so successful scientific
event. Hans-Joachim Bunge passed away on November 28,
2004. It was univocal consensus of the authors to dedicate
this proceedings volume to him, our "Great Man" of
quantitative texture analysis.

Obituary Notice for Hans-Joachim Bunge
29 July 1929 - 28 November 2004 Prof. (em.) Dr. Dr. h.c.
Hans-Joachim Bunge died untimely on November 28, 2004, at
the age of 75 years from a cerebral apoplexy. He is
survived by his wife Helga and his son Hans-Peter.
Hans-Joachim Bunge was born on July 29, 1929 in Zerbst, a
small town situated between Magdeburg and Dessau in
Eastern Germany.After having finished high-school in 1946,
he was a precision mechanic apprentice. In 1947, he
entered the Martin-Luther-University at Halle as a student
of physics. In 1955, he received his Dr. rer. nat. degree
with the Ph. D. Thesis "Magnetic Anisotropy of Cold Rolled
Iron-Nickel Alloys" from the Martin Luther University at
Halle. From then on his scientific interests have been
centered on crystal texture. In 1964, he was awarded his
Dr. habil. degree from the Humboldt University of Berlin
for the Habilitation Thesis "On the Representation of
Textures".
Hans-Joachim Bunge was research scientist at the Physics
Department of the University of Traffic, Dresden, from
1953 - 1955 where he was investigating hard magnetic
materials. From 1955 - 68 followed a fruitful period of
scientific work at the Institute of Crystal Structure
Research of the (East) German Academy of Sciences in
Berlin, dedicated to polycrystal X-ray diffraction,
texture analysis and technological applications. In 1968
he returned to Dresden to the Central Institute of Solid
State Physics and Materials Research of the German Academy
of Sciences, where he was engaged in texture analysis and
neutron diffraction. His promising career as a scientist
in East Germany came to an abrupt halt when he and his
family tried, in vain, to escape from ideological
persecution. They were imprisoned and kept apart from each
other from 1974-75 when they were finally allowed to leave
East Germany. From 1975-1976, he was DFG fellow (German
Research Foundation) with Prof. Dr. Günter Wassermann in
Clausthal-Zellerfeld and Prof. Dr. Rudi Wenk in Berkeley.
In 1976 he succeeded Günter Wassermann as Professor and
Head of the Institute of Physical Metallurgy of the
Clausthal University of Technology. From 1989-91, he was
Dean of the Department of Metallurgy and Materials Science
of this university.
After his retirement in 1997, he found a supportive new
scientific home at the Institute of Physics and Physical
Technology of the Clausthal University of Technology.
Until his last days, he supervised with great enthusiasm a
research project at the HASYLAB facilities in Hamburg,
financially supported by the German Research Foundation
(DFG), on texture analysis with hard synchrotron
radiation.
Hans-Joachim Bunge has achieved an outstanding scientific
work. In 1965 he managed to solve, independently with R.J.
Roe, one of the greatest challenges of quantitative
texture research - the pole figure inversion - by
developing the harmonic series expansion method. In 1969
he published the basic treatise on mathematical methods of
pole figure inversion "Mathematische Methoden der
Texturanalyse". The extended and revised English edition
of this book was published in 1982 under the title
"Texture Analysis in Materials Science". It is still
considered the comprehensive standard handbook in this
field of materials science. He was fond of bringing his
expertise to the world. It had been a tradition of his
institute for many years to organize annual workshops on
texture analysis and related topics. He is the author or
editor of 10 more books on quantitative texture analysis
and on anisotropic materials properties. He has published
more than 450 contributions to scientific journals and
conference proceedings. From 1986 to 2003, Hans-Joachim
Bunge was the editor of the journal "Textures and
Microstructures". Since 1978, he was member of the
International Committee of ICOTOM. From 1985 to 2004, he
was the speaker of the Special Committee for Textures of
the German Society of Materials (FA Texturen der DGM).
In recognition of his scientific achievements in materials
science, Hans-Joachim Bunge received a number of honors.
He was awarded, for instance, the degree of a Doctor
Honorary of the University of Metz (France) in 1979, the
degree of a Professor Honorary of the Beijing Polytechnic
University (China) in 1993, the Honorary Membership of the
Czech Metal Science Society in 1995, and the Honorary
Membership of the Texture Society of India in 2000. In
2003, he received the Carl-Hermann Medal of the German
Society for Crystallography.
His life was committed to science. Even within his
activities he always had time for students and his
colleagues. He still had many plans for the future, both
at work and personal. Hans-Joachim Bunge was an affable,
mild-mannered man of a uniformly cheerful and gentle
disposition. His loss will be grievously felt by a large
circle of friends and associates.
