What is it about?
Characterization of microscopic and macroscopic changes, induced by slight substitutions (± 1.5 at.%) of Al with Ni around ‘‘classic’’ composition Fe43.5Mn34Al15Ni7.5 and discussion of processing effects on the structure and mechanical properties of the alloys, while applying cyclic heat treatments under continuous Ar flow, instead of sealed evacuated quartz capsules, as reported by most of the authors

Why is it important?
Cyclic heat treatments under argon gas flow caused the formation of globular c-fcc grains, which strongly impeded abnormal grain growth. Moreover, the globular c phase was strongly stabilized, since it can hardly be dissolved by an additional solution treatment at 1200 C. The formation and stabilization of globular gamma phase could be an effect of high cooling rate during the cyclic heat treatment, due to continuous argon flow. This phenomenon may be of interest for researchers dealing with high-temperature stable phases.
Perspectives
Future work is necessary to evaluate the influence of the different chemical compositions on fibering and its relationship with the occurrence of texture and on abnormal grain growth in order to obtain conditions suitable for good SE responses.
