What are the lattice vacancies
The lattice vacancies are a stable feature of metals at all temperatures above absolute zero. By successive jumps of atoms, just like playing Chinese checkers, it is possible for a vacancy to move in the lattice structure and thus play an important part in diffusion of atoms by the lattice. Vacancies are not only present as a result of solidification but can be formed by raising the temperature or by irradiation with fast moving nuclear particles.
What are the Types of Acceptance Tests? There are two main aspects to acceptance testing: Measurement of Acceptability Comparison of acceptability or preference
