Dislocation densities and strain hardening rate in some intermetallic compounds

The strain hardening rate (SHR) of some intermetallic compounds is examined in regards of dislocation density. It is shown that a Taylor-type relation between stress increases and dislocation density is obeyed and that the SHR rate can be explained in terms of dislocation storage due to a very short mean free path of dislocations.
