The concept of a yield point in alloys is sometimes difficult to define because plastic deformation due to dislocation generation and movement is often a diffuse process rather than a singular event. Likewise, in the case of ceramics the non-linear stress- strain response is either due to extension of existing microcracks or formation of new microcracks. For most engineering design applications the 0.2% offset definition or other definitions of yield is favored and are subjective in nature. In this presentation we will introduce a new methodology and results on few high temperatures ceramics and alloys. We have already proved that at room temperature this new definition of yield is self-consistent in nature and, as such, provides an objective observation of the very onset of inelastic flow. The application of use of such a definition has proven to be very critical for in structural and functional alloys and ceramics used in automotive and fuel cell industries.
