Effect of cooling conditions on the magnetic properties of bainite transformation in an Fe-2%Mn-0.5%Cr alloy
(Elsevier Science Bv, 2008)
The effect of cooling conditions on the magnetic properties of bainitic reaction in Fe-2%Mn-0.5%Cr alloy have been investigated using Mossbauer spectroscopy. Results showed that the bainite phase is magnetically ordered ...
Silver and fluoride doped hydroxyapatites: Investigation by microstructure, mechanical and antibacterial properties
(Elsevier Sci Ltd, 2013)
Hydroxyapatite co-doped with Ag+ and F- ions was synthesized by the precipitation method and sintered at 1100 degrees C for 1 h. Samples were characterized by density, X-ray diffraction, Fourier transform infrared spectroscopy, ...
Comparison of thermally induced and deformation induced martensite in Fe-29% Ni-2% Mn alloy
(Elsevier Science Sa, 2007)
The morphology and crystallography of maitensite either formed by cooling to subzero temperatures (thermal effect) or by compression deformation were compared for different austenite grain sizes of Fe-29% Ni-2% Mn alloy ...
