Slip Summary • Plastic behavior: This permanent deformation behavior occurs when the … Plastic Lens or Glass Lens – Which one is Better? The plastic deformation of crystals occurs through the nucleation and motion of lattice defects known as dislocations. READ PAPER. Dislocations and Plastic Deformation deals with dislocations and plastic deformation, and specifically discusses topics ranging from deformation of single crystals and dislocations in the lattice to the fundamentals of the continuum theory, the properties of point defects in crystals, multiplication of dislocations, and partial dislocations. • Ease with which material is capable of plastic deformation is a function of dislocation mobility, i.e. Plastic Deformation. And they’re ready for you to use in your PowerPoint presentations the moment you need them. • Indeed, plastic deformation leads to the multiplication of dislocations, which strain fields start to interact more “closely”, hindering the dislocations motion. The factors playing an important role are ?

Fe, Ni, Co base alloys, Precipitation hardening (instead of dispersion, Ni-base superalloys have Ni3(Ti,Al) precipitates, Cold work cannot be used for increasing creep, Fine grain size is not desirable for creep. 8. 4. Swell in the presence of certain solvents. •Dislocation movement is similar to the way a caterpillar moves. Plastic deformation in the broadest sense means permanent deformation in the absence of external constraints (forces, displacements) (i.e. In plastic deformation, there is no easily measured constant relating stress to strain as with Young’s modulus for elastic deformation. external constraints are removed). Plastic deformation is the permanent distortion that occurs when a material is subjected to tensile, compressive, bending, or torsion stresses that exceed its yield strength and cause it to elongate, compress, buckle, bend, or twist.
