Microstructure, mechanical behavior, and crystallographic texture in a hot forged dual-phase stainless steel

In this work, the hot forging behavior of a dual phase stainless steel in temperature range 850–1250 °C was investigated. The study revealed occurrence significant cracking phenomenon for processing temperatures below 950 that attributed to combined effect intermetallic precipitation and severe deformation. EBSD examination highlighted continuous dynamic recrystallization both ferrite austenite microstructures above 1050 °C. Increasing 1250 increased low angle grain boundaries fraction lowered one high boundaries. This accompanied by gradual change crystallographic texture material. mechanical investigation showed plasticity, sharply dropped after at 850°, gradually recovered 1050°C. confirmed nanoindentation measurements remarkable increase hardness Young’s modulus 850°C 950°C due dislocation nucleation ? ?/? interface. enhancement movement vicinity 1050–1250 improved global properties forged steel.
