Electrical resistivity of quenched β brass I Temperature

In order to examine a role of vacancies in ordering during quenching the residual electrical resistivity of β brass has been studied as a function of quenching temperatures ranging from 100 to 450°C The resistivity immediately after quenching first increases exponentially with increasing temperatures up to 275°C and then decreases gradually although it increases again over 400°C The
