Twinning analyses in a magnesium alloy with tilting series scanning method using a TEM based orientation mapping system

A transmission electron microscopy (TEM) based orientation mapping system was employed to investigate the twinning behavior during hot rolling process of a magnesium alloy. Conducting scanning with the tilting series method, both {101¯1}−{101¯2} and {101¯2} twinning types could be unambiguously identified. It is also found that for {101¯1}−{101¯2} twinning the compositive influences of both twinning Schmid factor and the ease of potential basal slip within twinned area should be considered as the twinning selection criterion.
