...Abstract Abstract Deformation within a crystal lattice is governed principally by the presence of dislocations, which are two-dimensional defects in the lattice structure. Slip from shear stress is the most common deformation mechanism within crystalline lattices of metallic materials, although...

... are characterized by a high toughness and have no specific crystallographic slip planes. Consequently, they are assumed to be insensitive to the selective corrosion attack of slip planes (as occurs in crystalline alloys) that leads to stress-corrosion cracking (SCC). The plastic deformation of amorphous alloys...

It explains how ferrite and pearlite respond to deformation and how related features such as slip lines, dislocations, shear bands, and kinking can be detected as well as what they reveal. It also describes the structure of patented wires, cast steels...

... . The number of available slip systems can vary depending on the crystal structure, and these slip systems are essential in determining the manner in which materials deform under load. In ionically bonded solids such as salts, there are very few slip systems along which atoms can move. This is a consequence...

... investigation. In MVC, voids nucleate (initiate), grow, and coalesce to develop the final fracture surface that is dimpled. The most common process is one of pore (incipient crack) formation at or in a particle, followed by either void growth and linkage or by localized shear band slip deformation...
