Book Description
The present collection of articles focuses on the mechanical strength properties at micro- and nanoscale dimensions of body-centered cubic, face-centered cubic and hexagonal close-packed crystal structures. The advent of micro-pillar test specimens is shown to provide a new dimensional scale for the investigation of crystal deformation properties. The ultra-small dimensional scale at which these properties are measured is shown to approach the atomic-scale level at which model dislocation mechanics descriptions of crystal slip and deformation twinning behaviors are proposed to be operative, including the achievement of atomic force microscopic measurements of dislocation pile-up interactions with crystal grain boundaries or with hard surface coatings. A special advantage of engineering designs made at such small crystal and polycrystalline dimensions is the achievement of an approximate order-of-magnitude increase in mechanical strength levels. Reasonable extrapolation of macro-scale continuum mechanics descriptions of crystal strength properties at micro- to nano-indentation hardness measurements are demonstrated, in addition to reports on persistent slip band observations and fatigue cracking behaviors. High-entropy alloy, superalloy and energetic crystal properties are reported along with descriptions of deformation rate sensitivities, grain boundary structures, nano-cutting, void nucleation/growth micromechanics and micro-composite electrical properties.

Book Description
Deformation Geometry for Materials Scientists presents the study of macroscopic geometry of deformation, particularly on crystalline solids. The book discusses a wide range of topics on the deformation of crystalline materials. The text discusses concepts on stress and strain on materials and tensile tests. Linear elastic and plastic deformations; and the macroscopic geometry mechanism of slip and deformation twinning are covered as well. Materials scientists, engineers, and students of materials science will find this book a great reference material.

Book Description
This volume entitled Advanced Science and Technology of Sintering, contains the edited Proceedings of the Ninth World Round Table Conference on Sintering (IX WRTCS), held in Belgrade, Yugoslavia, September 1-4 1998. The gathering was one in a series of World Round Table Conferences on Sintering organised every four years by the Serbian Academy of Sciences and Arts (SASA) and the International Institute for the Science of Sintering (IISS). The World Round Table Conferences on Sintering have been traditionally held in Yugoslavia. The first meeting was organised in Herceg Novi in 1969 and since then they have regularly gathered the scientific elite in the science of sintering. It is not by chance that, at these conferences, G. C. Kuczynski, G. V. Samsonov, R. Coble, Ya. E. Geguzin and other great names in this branch of science presented their latest results making great qualitative leaps in the its development. Belgrade hosted this conference for the first time. It was chosen as a reminder that 30 years ago it was the place where the International Team for Sintering was formed, further growing into the International Institute for the Science of Sintering. The IX WRTCS lasted four days. It included 156 participants from 17 countries who presented the results of their theoretical and experimental research in 130 papers in the form of plenary lectures, oral presentations and poster sections.

Book Description
Strength of Metals and Alloys, Volume 3 (ICSMA 7) presents the proceedings of the 7th International Conference on the Strength of Metals and Alloys held in Montreal, Canada on August 12-16, 1985. The book includes papers on the work hardening of face-centered cubic single crystals; precipitation hardening; and microstructure evolution and flow stress during hot working. The text also covers papers on microstructure evolution and flow stress during hot working; the prediction of deformation textures in cubic metals; creep of copper-base shape memory alloys; and flow behavior of nickel-base superalloys at isothermal forging temperatures and strain rates. Grain refinement by recrystallization hot-rolling to achieve high strength and notch toughness in microalloyed steel plate; as well as the influence of mean stress on fatigue strength of TI-6A1-4V are also encompassed. The book further includes papers on the comparative mechanical properties of human bones; the effect of precipitation hardening on the decomposition of the solid solution in 7075 alloy during quenching; and the mechanical properties of stable and unstable austenitic stainless steels.
