in this research, aluminizing packs containing naf and nh4cl activators were used for aluminizing of pure titanium samples at 1100 ºc. the results showed that the layers of tial3, tial2, γ-tial, α2-ti3al, and α-solid solution are formed on titanium samples in both cases. however, the weight gain and the thickness of tial3 layer in treated samples with nh4cl activator are greater than those when...

For studying the thermodynamic properties of systems using statistical mechanics we propose an ensemble that lies in between the familiar canonical and microcanonical ensembles. From a comparative study of these ensembles we conclude that all these ensembles may not yield the same results even in the thermodynamic limit except at high temperatures. An investigation of the coupling between syste...
