摘要：

Fe-Al alloys show environment embrittlement related to hydrogen generated during the reaction of aluminum with water vapor. To investigate this relationship, micro-hardness measurements were made from alloys subjected to two different conditions after a drying treatment: holding at room temperature in a wet environment (dry-wet treatment) and holding in a wet environment followed by a dry treatment at 423 K (dry-wet-dry treatment). In the former case, and age-hardening phenomenon is observed; in the latter, an age-softening phenomenon is observed. Such changes in hardness are reversible in response to environmental conditions.
