      The present book on Strengthening Mechanisms in Crystal Plasticity provides such a coverage in a generally transparent and readily understandable form. It is intended as an advanced text for graduate students in materials science and mechanical : Argon, Ali.   To this end, the microstructural design of these composites is imperative especially in terms of the stress partitioning mechanisms among the constituent phases. Based on the characteristic microstructures of dual phase and multilayered steels, two polycrystalline aggregate models are constructed to simulate the microscopic lattice strain Cited by:

Subsequently, a detailed 3D structure of columnar grains in as-printed steel is constructed thanks to microscopic : Minh-Son Pham, Paul Hooper.

The deformation microstructures of two-phase alloys are discussed in detail in Sectionand at this point we recall that there are three aspects of the deformation structure that are of particular importance in determining the behavior of the material during subsequent annealing.

This work reviews the class of Al-rich TiAl alloys in terms of phases, microstructures, morphology, deformation mechanisms, mechanical behaviors along with a possible micromechanical modeling Author: Robert Brockman. Strain localization in ductile metals subjected to cyclic deformation is a commonly observed feature which can be regarded as the first sign of fatigue damage.

Cyclic strain localization can occur in different forms, e.g. in persistent slip band (PSBs), at notches at the free surface, at the tips of propagating cracks, at precipitate-free zones Cited by: 3. Continued cyclic deformation will lead to a gradual surface roughening of extruded PSB material, see figure 6c, which can be estimated semi-quantitatively [14,26,30] and which should be similar in polycrystals and in single crystals.

Book Description. A comprehensive treatise on the hot working of aluminum and its alloys, Hot Deformation and Processing of Aluminum Alloys details the possible microstructural developments that can occur with hot deformation of various alloys, as well as the kind of mechanical properties that can be anticipated.

The authors take great care to explain and differentiate hot working in the. In randomly oriented f.c.c. polycrystals, we find that the ratio of the tensile stress that must be applied for plastic deformation to the critical resolved shear stress is approximatelywhich is known as the Taylor factor.

Strain Hardening Another effect that accompanies plastic deformation is strain hardening. Deformation of a. Basic description. Plastic deformation occurs when large numbers of dislocations move and multiply so as to result in macroscopic deformation.

In other words, it is the movement of dislocations in the material which allows for deformation. If we want to enhance a material's mechanical properties (i.e. increase the yield and tensile strength), we simply need to introduce a mechanism which.
