Twinning analyses in a magnesium alloy with tilting series scanning method using a TEM based orientation mapping system
Résumé
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 {10 (1) over bar1) {1012} and {10 (1) over bar2} twinning types could be unambiguously identified. It is also found that for {10 (1) over bar1) {10 (1) over bar2) 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.
