Evolution of {10 (1) over bar2} extension twinning with deformation temperature was investigated in randomly oriented polycrystalline magnesium using neutron diffraction (measurement of twinned volume) and acoustic emission (detection of twin nucleation) technique. Despite of the monotonic decrease of twinned volume with increasing temperature, the number of nucleated twins is similar in the midtemperature (100-200 degrees C) range, which indicates decreasing extent of twin growth at higher temperatures. At 300 degrees C the twinning is negligible.
