In this study, fresh attempts have been made to identify and estimate the phase constituents of a high-silicon, medium carbon multiphase steel (DIN 1.5025 grade) subjected austenitization at 900 °C for 5 min, followed by quenching low-temperature bainitizing (Q&B) 350 200 s. Several techniques were employed using different chemical etching reagents either individually (single-step) or in co...
