IMPACT OF SOLUTION ANNEALING ON PROPERTIES OF DUPLEX STEEL

Popis výsledku v původním jazyce

This paper deals with the impact of solution annealing on the properties of X2CrNiMoN2253 duplex steel. Experimental specimens were 100×100×150 mm forged and air-cooled pieces, which were solution-annealed at several temperatures changed in 20 °C steps between 1020 and 1120 °C. Mechanical tests conducted on these processed specimens included tension tests and Charpy impact tests at room temperature and at -46 °C. The results were compared with the requirements stipulated in the EN 10088-3 standard and with the minimum requirements for X2CrNiMoN2253 forgings for coastal oil and gas extraction set out in technical delivery conditions. Microstructures of the specimens were explored using optical and electron microscopes and EBSD analysis. EBSD measurement showed significant ferrite texture in some specimens, whereas no signs of texture were detected in austenite in any of the samples. The causes of the ferrite texture were investigated and its impact on properties of the duplex steel was explored.
