Abstract

The present study evaluated the mechanical properties in monotonic and cyclic stress of a FeMnAlC steel designed by thermodynamic calculations with predicted stacking fault energy values within Twinning Induced Plasticity (TWIP) effect actuation range. The material was processed by spray forming, using recycled feedstock from structural steel and aluminum engine block. The deposit was mechanically formed by rotary swaging and subsequently annealed. This processing route resulted in a single-phase austenitic material with minimal texture. The steel presented nanotwinning deformation during the monotonic test and an elongation at fracture of 73%. The fatigue limit was determined by the staircase method, and deformation twins were also nucleated during the cyclic straining in the surface specimen and in the fatigue crack propagation path.
