Composite materials with titanium-alloy matrix are currently the class of material with the highest specific resistance at temperatures up to 800nbsp;C. The main hurdle to their application is their final cost. Even if it is clear that the costs of constituent materials are decreasing due to volume production effects, the production processing costs remain high due to the batch production
