Fig. 2From: EPMA quantification on the chemical composition of retained austenite in a Fe-Mn-Si-C-based multi-phase steelCompositional inhomogeneities in the standard specimens; a C Kα (SRM 1767), b Mn Kα (SRM 1761), and c Si Kα (SRMC 1151a) maps. The maps were obtained under 20 keV(Accelerating voltage) and 3 × 10− 7 A (Probe current)Back to article page
