- Abstract
- The influence of Si and Al on the lattice parameter and stacking fault energy (SFE) of austenitic steel was studied. X-ray diffraction indicated that 2.5 wt.% Al alloying increased the austenite lattice parameter by 1.41 x 10(-3) nm, whereas 2.5 wt.% Si alloying had little effect. Partial dislocation separation measurements from weak-beam dark-field images indicated that 2.5 wt.% Al alloying increased the SFE by 12-17 mJ m(-2) and 2.5 wt.% Si alloying decreased the SFE by 6-7 mJ m(-2).
