Vv. Cherkasov et al., EFFECT OF THE EXPOSURE TIME BETWEEN HARDENING AND TEMPERING ON THE STRUCTURE AND MECHANICAL-PROPERTIES OF AN AL-MG-ZN ALLOY, Metal science and heat treatment, 36(1-2), 1994, pp. 35-37
Under production conditions articles are not placed in the furnace for
aging immediately after hardening. The duration of exposure at room t
emperature between hardening and tempering has a considerable effect o
n the properties of aluminum alloys.
