Effect of Aging Temperature and Time on Secondary Phase Precipitation and Texture in an Ultrafine Grained 2205 Duplex Stainless Steel after Cold Rolling

What is it about?

The present work evaluates the precipitation of secondary phases in a cold rolled ultrafine grained 2205 duplex stainless steel after aging at temperatures ranging from 600°C to 950°C for different annealing times (300-86400 s). Sigma and austenite phase volume fractions increased with ageing time Although mechanical strength was increased, the ductility was reduced as the secondary phase precipitation proceeded.
