The loss of single vacancies in metals during quenching

  • Published:
Czechoslovak Journal of Physics B Aims and scope

Abstract

The Lomer equation, describing the rate of change of single vacancy concentration in a metal specimen during exponential quenching, was numerically solved for different quenching temperatures and different quenching rates. A relation has been found between the constantb, which characterizes the initial quenching rate, and the quenching temperature leading to the same percentual loss of vacancies. This relation enables us to determine the conditions of quenching, yielding the predetermined percentage of retained vacancies.

The possibility is discussed of applying the above results in measurements of the formation energyEfF, to estimate the migration energyE M and to determine the change of the mean number of jumps during quenching.
