This book is one volume of the proceedings of the second conference on Environmental Degradation of Engineering Materials held at Virginia Polytechnic Institute on September 21-23, 1981. Papers in this volume describe fatigue and corrosion fatigue, liquid metal embrittlement, nuclear environment effects, degradation of composites and polymers, stress corrosion cracking and both analytical and experimental attempts to simulate or model the process of degradation. The other volume of the proceedings Environmental Degradation of Engineering Materials in Hydrogen contains papers which describe hydrogen uptake and transport by metals, hydrogen adsorption and evolution from metals and hydrogen embrittlement of metals. Forty-two papers have been abstracted and indexed for the Energy Data Base.
