Glossary of technical terms for the use of metallurgical engineers Terms starting with alphabet ‘O’ Objective – It is an optical element that gathers light from an object being observed and focuses the light rays from it to produce a real image of the object. Objectives can be a single lens or mirror, or combinations of several optical elements. They …
Read MoreGlossary of technical terms for the use of metallurgical engineers Terms starting with alphabet ‘N’ Nabarro–Herring creep (NH creep) – It is a mechanism of deformation of crystalline materials (and amorphous materials) which occurs at low stresses and held at high temperatures in fine-grained materials. In Nabarro–Herring creep, atoms diffuse through the crystals, and the rate of creep varies inversely with the …
