Application of ductile cast iron ADI is feasible and cost-effective, provided that there is a clear understanding of the mechanisms for the formation of their high complex mechanical properties. The use of such materials for the production of variable parts of machinery, or in other units of automobile and machine building will significantly extend the life of the equipment. It is established that the level of mechanical characteristics of the ADI cast iron varies in full accordance with the theoretical concepts of the influence of the tempering temperature on the formation of mechanical properties of such materials. The previous plastic deformation does not affect the mechanism of formation of pseudo-elasticity. The tendency to dampening increases with an increase in the temperature of isothermal quenching. The damping behavior of a material is a consequence of the formation of pseudo-elastic twins in the structure of the transformed martensite.

The temperature and velocity sensitivity of the mechanical properties of TiAl-based alloys were investigated. The structure was determined by scanning electron microscopy in SEI mode. Mechanical properties were determined by the results of tensile and bending tests. It was found that the temperature and velocity dependence of the mechanical properties in alloys with 47% Al is practically absent. This makes them promising for use as structural materials, due to the stability of their properties.
