FIELD: metallurgy.
SUBSTANCE: invention refers to thermal treatment and be used at thermal stabilisation of dimensions of high precision parts of alloys AK4-1 ch. The procedure consists in quenching, and in artificial ageing performed in two stages at temperature 190°C during 6 hours each. Mechanical treatment is performed upon the first stage of ageing.
EFFECT: reduced duration of process.
