The twinning activity in random textured cast magnesium during monotonic, room temperature tension and compression tests was monitored by acoustic emission (AE) and neutron diffraction (ND). The AE detected higher twin nucleation activity in tension than in compression. The correlation of AE with the ND data indicates that in compression the nucleation of twins is followed by rapid growth, unlike in tension in which twin variants with limited growth were observed.
