A review on the effect of creep and microstructural change under elevated temperature of Ti6Al4V alloy for Turbine engine Application

Creep is the likelihood of a solid material to permanently respond to deformation primarily due to initial mechanical stresses.Creep could be severe failure condition in materials that are subjected to heat and structural load which often occur near the melting point for a long period of time as it is the case in turbine engine under operating conditions. Creep is however strain accumulated and time dependent. This paper presents a review on processes models of experimental activities on the creep behavior of Ti6Al4V alloy under different high temperature applications andapplied stresses. This review was conducted by considering the material characterizations that have been carried out on some Ti6Al4V alloys at various levels of high temperatures by previous researchers. This will also feature in a related on-going investigation from a research study currently being undertaken by the authors. It however describes the major causes of mechanical failure of engineering components or structure due to creep mechanism.
