摘要

The Russian corrosion-resistant 1441 alloy is the most workable material among Al-Lirnalloys in terms of cold rolling. Clad sheets of 1200-1800 mm in width and up to 7000 mm inrnlength (including some with the thickness down to 0.3 mm) are cold rolled in coils. Alloyrn1441 sheets are applied in seaplanes, developed by the design office named after Beriyev,rnas the primary structural material. Fracture toughness, tension properties, fatigue crackrngrowth rate (FCGR) and durability of cold rolled 1441 alloy sheets and extruded panelsrnhave been determined. Results of the tests undertaken are discussed in the presentrnpaper.
