Microstructure of austenitic stainless steels of various phase stabilities after cyclic and tensile deformation

Popis výsledku v původním jazyce

The microstructures of two metastable high-alloyed CrMnNi cast TRIP steels and a stable AISI 316L austenitic stainless steel were studied in detail after tensile and cyclic deformation. Electron backscattered diffraction was employed to localize the martensitic phase deformation and electron channeling contrast imaging to describe the typical dislocation arrangements. These were complemented by transmission and scanning transmission electron microscopy. The TRIP steel with the lowest austenite stabilityshows a more pronounced martensitic phase transformation realized via intermediate formation of epsilon-martenite. Martensitic phase transformation also occured in the stable 316L steel with a small volume fraction of alpha?-martensite, but only with cyclic deformation at low temperatures and/or at very high plasic strain amplitudes.
