Grain-boundary strengthening (or Hall–Petch strengthening) is a method of strengthening materials by changing their average crystallite (grain) size. It is based on the observation that grain boundaries are insurmountable borders for dislocations and that the number of dislocations within a grain have an effect on how stress builds up in the adjacent grain which will eventually activate

Dec 19 2019 · INTRODUCTION to Casting Alloys. A casting alloy is defined as for dental purposes as a metal-containing two (or ) more elements in which one of the metals and all of which are mutually soluble in Molten State. Although there are some similarities between the characteristics of pure metals alloys addition of other metals to pure metal complicate the picture relative to certain fundamental
