FIELD: thermal processing of metals and alloys, in particular, quenching of sheet blanks and other elongated parts. SUBSTANCE: method involves heating part to predetermined temperature; locating part in quenching tank and providing intensified cooling by supplying cooling liquid from other vessel; providing intensified cooling of part by increasing liquid level in tank; filling tank to predetermined level for 0.05-30.00 min. Part to be quenched has length making 1.3-250.0 of its maximal thickness or diameter. EFFECT: improved quality of quenched part due to providing for uniform hardness over the entire length of part and reduced extent of residual deformation. 6 cl, 2 dwg
