Testing procedure

Mechanical properties of were investigated using an Instron 5969 
testing machine with the maximum load capacity 50 kN. 
Tension and compression tests were carried out at room temperature 
with the initial strain rate equal to 1 × 10-3 s-1. 
All specimens were cut out along ED. Flat tensile specimens, 
with thickness equal to 2 mm and dimensions of the gauge 
section 2.5 mm × 14 mm, were machined using wire electrical 
discharge machining (EDM).Height and diameter of the compression 
specimens were 8 mm and 7 mm, respectively.
