Excellent propositions of elemental introduction, heat treatment and mechanical characterization have established strong implement oriented studies in Ti-based alloys. Unique combination of different mechanical properties has made these alloys an attractive subject to biomedical and aerospace applications. The main variables of biomedical requirements have been desires of exposure similar to bones in body fluid medium, where as creep and fatigue resistance have been the primary variables for aerospace applications. Ti-alloys have versatile implications from powder, foil, and directional solidification and spray depositions route with generally hot isostatic pressing deformation routes for consolidation or thickness reduction. The stability of microstructure on exposure at high temperature can be controlled by rate of grain size coarsening, precipitation and dispersion hardening phenomenon within either duplex or lamellar microstructure. Role of mixed climb has been used to explain creep deformation in accordance with dislocation emission and absorption at the interface of phase transformation and straightening at high temperature. Interrelation of different variables in response to lamellar topography has been found to be attractive to utilize the alloy for various applications. Studies on microstructural detail, strength, density, wear, grindability, creep and fatigue properties have been described in the review in a short manner. The aim is to reproduce consideration of innovative approaches in Ti-base alloys as a modern trend.
