In a series of torsion tests, we have analysed the behaviour of commercial purity. aluminium_(99.5 % Al) during a strain rate change. The strain rate range 5 x 10 -3 s -1 to 0.15 s -1 for temperatures between 0.7 and 0.8 T f (400°C, 450°C and 500°C) has been explored. It is often assumed that p m , density of mobile dislocations, remains constant during a rate change. This assumption is in conflict with our observations and it is concluded that p m must decrease during the increase of the… CONTINUE READING
