Mechanical properties of AA5083 in different tempers at low temperatures

[摘要] Aluminium alloy 5083 was chosen for use in the critical cryogenic applications of shipboard transportation of liquefied natural gas (LNG). In the present work, the tensile, Charpy impact, bend and fatigue crack propagation behaviours of aluminium alloy 5083 in temper O, H112, and H32 were investigated both at room and cryogenic temperatures.
