Gas nitriding of titanium alloy Timetal 205

Samples of a titanium alloy Timetal 205 were treated by thermochemical gas nitriding using differential scanning calorimeter equipment, in nominally pure nitrogen, at 1040 and 1160 °C for 1, 3 and 5 h. X-ray diffraction analysis of the samples was carried out to identify new phases of chemical compo...

Beschreibung
Zusammenfassung:	Samples of a titanium alloy Timetal 205 were treated by thermochemical gas nitriding using differential scanning calorimeter equipment, in nominally pure nitrogen, at 1040 and 1160 °C for 1, 3 and 5 h. X-ray diffraction analysis of the samples was carried out to identify new phases of chemical compounds in the nitrided layer. Microstructures were analysed using scanning electron microscopy. Cross-sectional microhardness profiles of the samples were obtained using a Knoop indenter.
