Grain boundary chromium depletion in austenitic alloys
Journal of Materials Science, 2010It is widely accepted that thermally induced grain boundary chromium depletion in austenitic alloys such as austenitic stainless steels and Ni base alloys can lead to inter-granular stress corrosion cracking (IGSCC) of high temperature components during service.

Martensite start temperature and the austenite grain-size
Journal of Materials Science, 2010The dependence of the martensite start temperature on the austenite grain-size is modeled based upon aspects of martensite nucleation and validated by data reported in the literature. The results obtained support the view that grain boundaries provide an environment for the formation of martensite embryos in annealed austenite.

Spreading of Extrinsic Grain Boundary Dislocations in Austenitic Steel
Physica Status Solidi (a), 1979The dependence of the spreading process of extrinsic grain boundary dislocations (EGBD's) on grain boundary state and misorientation, and spreading kinetics in austenitic steel is investigated. Spreading of EGBD's at non-equilibrium grain boundaries obtained by successive cold rolling and annealing treatments at a temperature much lower than 0.8Tm is ...

Role of annealing twins in austenite grain growth
Metal Science and Heat Treatment, 19781. The change in the structure of the boundaries of recrystallized austenite grains during heating and the development of breaks in the boundaries are due to annealing twins growing from the breaks in the boundaries or near them. 2. Large numbers of annealing twins not connected with the boundaries of the matrix are observed in large ...

Evolution of Special Grain Boundaries in Austenitic Steels
Materials Science Forum, 2008AISI 304 type austenitic stainless steel samples were subjected to different thermomechanical treatments in order to investigate the effect of thermo-mechanical treatment on the grain boundary structure of the material. Electron back scatter diffraction measurements have been carried out in order to obtain information about the boundaries of the ...
