Changes in the structure of alloy on the matrix of FeAl intermetallic phase after primary crystallization and homogenizing treatment

In this work are presented results of examinations of the influence of the structure after primary crystallization and after homogenizing treatment. The performed structural examinations of alloy on FeAl intermetallic phase matrix had proved, that after a primary crystallization it has a coarse grain structure. Application of homogenizing treatment at temperature 1050 °C during 72 h leads to decay of growth twins, changes the distribution of dislocation in a manner enabling a hot plastic working.
