title = "Merging of the α and Β relaxations and aging via the Johari-Goldstein modes in rapidly quenched metallic glasses",
abstract = "This paper provides evidence that the physical aging of deeply and rapidly quenched metallic glasses is promoted by the Johari-Goldstein slow Β relaxation, resulting in a significant irreversible increase in the mechanical modulus on initial heating. Dynamic mechanical analysis has been used to characterize relaxation phenomena of a strong and a fragile metallic glass. In addition, we can extrapolate the temperature dependence of Β - and α -relaxation peaks to higher temperatures and calculate the merging temperature for both types of glasses.",
