摘要：
The formation mechanism and morphology of secondary austenite (gamma (2)) were investigated using light and scanning electron microscopy in lathy ferrite microstructure of a cast 22/7/2 copper-bearing duplex stainless steel isothermally transformed at temperatures from 800 degreesC to 1150 degreesC. It was established that its formation obeys the Johnson-Mehl equation and is temperature and time dependent. The precipitation sequence processes have been discussed and some aspects of precipitation behaviour are explained.
