摘要：

In this paper the effect of immersion duration on mechanical properties of cyrolled and non-cryorolled A5052 aluminium sheet alloy were studied. The sheets with and without annealing were rolled up to 30 % reduction at liquid nitrogen temperature. The mechanical behaviour of the sample were evaluated through hardness and tensile tests performed at room temperature. The evolution of microstructure was investigated using optical microscopy (OM). The optimum immersion duration of A5052 A1 sheet alloy was 60 minutes as the hardness, tensile and yield strength were the highest for annealed sample with and without directly cryorolled. All the cryorolled samples showed elongated grain. (C) 2016 The Authors. Published by Elsevier B.V.
