Phase transformation in titanium alloys on high temperature exposure has been studied. The central theme of review includes the study of basic development in phase transformation, microstructural features, acceptability of crystalline modification, precipitation and intermetallics formation. Effects of alloying elements to the standard systems have been studied. Lamellar microstructure in titanium aluminide systems forms various typical fronts of microstructural changes, where equiax, duplex, ultra fine grained combinations in lamellar or other phases produce versatile implications to the scenario. Ti-6Al-4V systems have been referred to as the 'work horse' of component manufacturing in industry and airways. Twinning, an important deformation mechanism, arises from stress fields associated to misfitting interfacial dislocation or shear reshuffle. Mostly lamellar topography of these systems shows a better creep life after reduction of dislocation climb process by segregated solutes at ledges of lamella. Industrial, biomedical, airways, aerospace and electrical sensors industry are main component manufacturer from these different standard alloy systems.
