Title: | Study of Alpha-Sigma Phase Transformation in Mechanically Alloyed Fe-Cr-Sn Alloys | Authors: | Costa, B. F. O. Caër, G. Le Campos, N. Ayres de |
Issue Date: | 2001 | Citation: | physica status solidi (a). 183:2 (2001) 235-250 | Abstract: | The solubility of tin is significantly extended by mechanical alloying in near equiatomic Fe-Cr alloys. The influences of Sn concentration and of grain size on the kinetics of formation of the sigma-phase have been studied using different techniques. The sigma-phase formation is much faster for as-milled alloys than it is for conventional alloys. The sigma-phase formation rate decreases with the increase of Sn concentration in alloys with nanometer-sized grains as it does in coarse-grained alloys. The mechanisms which are responsible for the slowing-down of the alpha-sigma transformation are different in both kinds of alloys. | URI: | https://hdl.handle.net/10316/8207 | DOI: | 10.1002/1521-396X(200102)183:2<235::AID-PSSA235>3.0.CO;2-Z | Rights: | openAccess |
