The document provides approximate values for vacancy concentration and dislocation density in metals. It states that the vacancy concentration in a metal near its melting point is between 10^-5 and 10^-4, while the dislocation density in heavily deformed metals ranges from 10^11 to 10^12 cm/cc. Additionally, it mentions that plastic deformation in crystalline solids begins when dislocations start to slip.

Approximately what is the vacancy concentration in a metal at a tempe.pdf
- 1. Approximately what is the vacancy concentration in a metal at a temperature just below its melting point? Approximately what is the dislocation density (in cm/cc) in a heavily deformed metal? When dislocations start to slip in a crystalline solid, what will happen to the solid? Solution a) Approximate vacancy concentraion in a metal at temperature just below its melting point = 10-5 - 10-4 b) Dislocation density in heavily deformed metal = 1011- 1012 cm/cc C) Plastic deformation starts when dislocatons start to slip in a crystalline solid
