Temperature dependence of yield point of Al3Ti alloys for L12-structure

Abstract

The results of research of temperature dependence of mechanical properties alloyed single-phase and eutectic alloys based on L12 intermetallic of the ternary Al-Ti-Cr system are presented. It is shown, that in the temperature interval of 20-800 ⁰С strength of alloys with eutectic structure exceeds strength of single-phase alloys on the basis of this intermetallic. Both classes of materials demonstrated a good combination of high-temperature strength and heat resistance and can be used as high-temperature materials and coatings.
