High Plasticity of an Iron Aluminide-based Material at Low Temperatures

Abstract

Aims: To compare surprisingly high plasticity in compression at low temperature of high-quality compacts prepared by spark plasma sintering from atomized Fe-30.8Al-0.35Zr-0.11B (at%) powder with tensile tests at the same conditions. Study Design: Compressive tests and tensile tests at room temperature and at 77 K, scanning and transmission electron microscopy, measurements of Young's and shear moduli data of the sintered material from room temperature to 80 K.
