Antiphase domain boundary tubes in plastically deformed Fe-Al alloys with B2 ordered structure

TEM observations of antiphase-domain boundary (APB) tubes in several alloys of different composition are presented, revealing how the probability of observing the APB tubes varies with Al concentration. The probability is smaller for alloys with higher Al concentration. APBs are also noted to be a r...

Zusammenfassung:	TEM observations of antiphase-domain boundary (APB) tubes in several alloys of different composition are presented, revealing how the probability of observing the APB tubes varies with Al concentration. The probability is smaller for alloys with higher Al concentration. APBs are also noted to be a result of the film effect of the TEM specimens. (AIAA)
