Structural properties of (Nd 0.33 Eu 0.2 Gd 0.47)Ba 2 Cu 3 O y studied by magnetic and infrared measurements. WebBoth were found to exhibit a simultaneous TWIP+TRIP plasticity enhancing mechanism where deformation twins and alpha'-martensite formed independently of twinning with strain. Interrupted tensile tests were conducted in order to investigate the differences in deformation structures between the two microstructures.
