4.3. Tensile Testing of 1050H14 Al
The tensile test specimens of 1050H14 Al were prepared both perpendicular and
parallel to the extrusion direction. The test samples were machined according to ASTM
E8/E8M-08 standard (ASTM 2001) using a electro discharge machine. The dimensions
of the tested tensile test specimens are shown in Figure 4.9. 1050H14 tensile test
specimens containing a weld zone at the middle were also prepared tested (Figure 4.9).
The tensile tests were conducted at a cross-head speed of 5 mm min -1
, corresponding to
a quasi-static strain rate of 1.66 x10 -3
used to measure the displacement.
