FeMnAlC alloys are lower density (6.5-7.2 g/cm3) than traditional military steels while maintaining similar energy absorption capabilities. Controlling the hardness of the material is critical to performance in extreme applications. To date, the majority of work in this class of steels has focused on wrought sheet for automotive applications, with typical ranges of 10-15%Mn and 1-4%Al. This study examines thick plate with a nominal chemistry of 30% Mn, 9%Al and 1%C, in the wrought condition, and subject to heat treatment. Microstructural and mechanical variations based on thermomechanical processing history are discussed.
