TITANIUM-STEEL COMPOSITION MATERIAL SEPARATION METHOD

摘要

FIELD: processes for separating metallic materials, possibly in processing industry for recovery of waste of titanium-steel laminate composition materials. ^ SUBSTANCE: method comprises steps of thermally acting upon material till temperature of active inter-phase inter-action of titanium and steel 950 -1000°C; soaking at such temperature for 3 - 10 h till formation in zone of titanium and steel joining of fragile layer with thickness 180- 220 micrometers; realizing quenching in water or aqueous solution of NaCl with concentration no more than 15% for achieving spontaneous separation of composition material. According to invention outer force action is not necessary for separation of titanium and steel of composition material. ^ EFFECT: new technology of separation due to growing fragile layer of optimal thickness in joining zone of titanium and steel for further spontaneous separation of material after quenching it in selected cooling media. ^ 1 tbl, 4 ex
