Abstract
The MAB phases are a group of ternary borides with stacking transition metal boride sublattices (M- B) and Al or Zn interleaves (A). They exhibit intrinsic laminated crystal structures. Textured bulk Mn2AlB2 samples were fabricated to study the compressive behavior of Mn2AlB2 at quasi-static and dynamic strain rates in relation to its global orientation (b-axis). The grain orientation and its indicator were obtained using X-ray diffraction. The quasi-static compressive strengths were measured using a conventional load frame at a strain rate of 10-3 s-1. Dynamic compressive strengths were obtained using a Kolsky (split-Hopkinson) bar at strain rates up to 103 s-1. When loading parallel to the b-axis (parallel to b-axis), the quasi-static compressive strength was 1285 +/- 80 MPa and was the highest value among the two strain rates and two orientations investigated. Under quasi-static conditions, the compressive strength at failure of the parallel to b-axis was 12% higher than loading perpendicular to the b-axis orientation (perpendicular to b-axis), respectively. Under the dynamic regime, the compressive strengths of both orientations were about 10% lower concerning their quasi-static values, in contrast to what has been seen in similar MAX phase (layered hexagonal metal carbides and nitrides) highly- oriented investigations. In-situ deformation imaging and post-mortem scanning electron microscopy suggest that the pre-existing microcrack distribution and a difference in the fracture mechanisms could be responsible for the lack of anisotropic solid behavior.
