SHEET OF PURE TITANIUM WITH EXCELLENT BALANCE BETWEEN DUCTILITY AND STRENGTH

摘要

FIELD: metallurgy.SUBSTANCE: sheet is made from pure titanium and contains titanium and unavoidable impurities. It features yield point of 215 MPa or higher, mead size d of the grain making 25 mcm of larger and 75 mcm or smaller, and hexagonal crystalline structure. Appropriate grains in hexagonal crystalline structure feature means Schmidt factors (SF) of twins 11-22 with rolling direction oriented along their axes. Means Schmidt factor (SF) and grain means size d satisfy the following relationship: 0.055?[SF/?d]?0.084. Heat exchanger plate comprises sheet of pure titanium and as integral component.EFFECT: high ductility and strength, heat exchange plate with such sheet.2 cl, 6 dwg, 3 tbl
