[Text] Foreword to second edition
The "Reactor Ma,terial Technology" mon~graph published in 1968 was sold
out rapidly which indicates reader interest in this book. an the years
after the book was published many publications appeared in the Soviet Union
and abroad that considerably expanded our concepts on the rroper-ties of
reactor meterials,and on the mechanism of the processes occ~:sri.ng in the:~e
materials during their use.
The second edition of this book was reWritten takin~ ir_to uccount the lates~
data on the ph,ysical, mechanical and nucleax properties of uranium~ plu-
tonium and thorium, as well as of their compounds. .
As before, basic attention is devoted to the description of nuclear fuo~
_ and structural ma.terials, the processes occurring in them under -the ~nflu-
e~ce of radiation and other factors related to operating conditionso A.lon~
wi'cYi this, prob~.ems are more fully considered of the change in the most im-
portant properties, identifying the pa,tterns of such changes that would .
make it possible to outline ways to improve tha operating characterist~cs
of the materials. Prc':lems axe elucidated of the life of the jacket ~struc-
~ tural) materials, in particular of the importance of streng`~h properties
and their relationship to the formation and precipitation of he:iium when
irradiated, problems of corrosion etc.
In connection with a great number of new data and the necessih.y of more
detailed treatmEnt of the ma,~erial technology and metal phy~sies aspeci;s
of reactor ma,terials, the authors considered it expedient to eliminate
sections of the book concerning phyaical and thermophysical problome of
the :ictive zone of the rea.ctor. _

In the second edition being offered, the general structurP of the book~
the o~cler and titlea of several chaptera and sections ,~ere preserved;
however~ the contents axe completely renewed, the majority of chapters were
newly written taking into account new data, while the xemaining chapters
were re~rritten and amplified considerably.

(Text] In the course of scientific and technical progress there is all the
more growth in requirements for structural materials. This was reflected
in the reaolutions of the 25th Congress of the CPSU where ttiey talked about
the development of new polymer materials and improved quality of existing
_ ones. Tc meet these tasks will require further development of structure
research and determination of the relationships between the structural con-
_ stit ution and a complex of physical and mechanical characteristics of polymer
materials; to control the process of polympr synthesis w~ll requize struc-
tural research at the solutions level. Determination of the correct mode
- cF m~terial application in tLrn is not possible without knowledge of struc-
t:ural tr3nsformations during the action or a varying form of external factors
on the polymer material. All of the above-listed problems were examine3 in
det ail at the Thizd All-Union Conference on the Mechanics of Polymers which
was held in 1976 in Riga and reflected in the transactions put forward to
the reader of the collection.
The content of articles in the first part of the collection encompasses a
broad circle of questions associated with the structure of a polymer material
at different structural levels. All the work on the problems and produced
results can be reduced to the following basic directions: 1) uncovering -
_ new principles of structure and property relationship and 2) development of -
new methods for controlling structure and the properties associated with it.
Mos t works have been associated with study of the structural state of polymers
at various levels.
Recently more attention is being given to properties characterizing the sys-
tem of macromolecules as a whole--like molecular mass, molecular-mass dis-
tributiun, etc. In conJunction with this exists the necessity to conduct
experimental and theoretical research, determiiie the nature of the relation-
ships between molecular distribution and individual structural elements such
