Strength of Metals and Alloys is a collection of papers presented at the 5th International Conference on the Strength of Metals and Alloys held in Aachen, Germany, on August 27-31, 1979. Contributors explore advances that have been made in understanding the strength of metals and alloys and cover topics ranging from plasticity and crystal structure to microstructural models for friction and wear; dynamical effects in deformation; and microscopic mechanisms of metal fatigue. This volume is comprised of 13 chapters and begins with an analysis of the differences between the plastic deformation of face-centered cubic, hexagonal close-packed, and body-centered cubic metals in relation to intrinsic dislocation mobilities resulting from the interaction of the dislocation core with the crystal lattice. The reader is then introduced to dislocation models for fatigue and their application to cases of friction and wear. The following chapters focus on the mechanisms controlling the creep of single phase metals and alloys; precipitation and dispersion hardening; deformation of polycrystals; solid solution hardening; and superposition of alloy hardening, strain hardening, and dynamic recovery. The results of in situ deformation experiments using high-voltage electron microscopy are also presented. The final chapter is devoted to the mechanisms underlying the recovery and recrystallization of doped tungsten. This monograph will be a valuable resource for metallurgists and materials scientists.
