Abstract:

The article deals with the melting, ingot casting, extrusion, welding, and corrosion resistance of the MA10 Mg-base alloy, which contains Al, Cd, Ag, and Mn. According to the authors, melting, ingot casting, and extrusion procedures for this alloy do not differ markedly from those used for other Mg alloys. Al and Mn are added during melting, while Cd and Ag are added in the mixer. Ingots are cast by a semicontinuous process and then conditioned by machining. Round billets are 345 mm in diameter and 600-1100 mm long flat billets are 160 x 540 x 700 mm. Good surface quality and uniform fine-grained structure are obtained at extrusion temperatures of 350-400 C and extrusion rates not exceeding 0.3 mmin for bars, plates, and panels, and 0.5 mmin for tubes. At higher extrusion rates transverse tears form. The structure of the MA10 alloy consists of a complex Mg-Al-Mn-Cd-Ag solid solution and a complex intermetallic compound which probably serves as a strengthening phase. Author
