Cold-work induced phenomena in B2 FeAl intermetallics

For the last several years we have been conducting systematic studies of microstructural changes and mechanical behavior of B2 FeAl alloys, cold-worked by ball-milling and shock-wave loading. Fundamental physical phenomena induced in iron aluminides such as an accelerated chemical disordering, increase in the lattice parameter, non-magnetic/magnetic transformation and formation of nanocrystals in ball-milled powder particles are presented and discussed.
