Mechanical Properties of Co-Al-Mo-Nb Intermetallic Alloys

Abstract:

The results of the experimental study of the mechanical properties and structure of the Co-9.5Al-2.9Mo-4Nb, Co-9.1Al-5.2Mo-4.7Nb, and Co-8.9Al-6.5Mo-9.3Nb alloys were presented. The Young’s moduli in the studied alloy samples were found to be smaller than those of Ni₃Al-based and Co₃(Al,W)-based alloys. The eutectic structure was observed in all studied alloys. Cuboids of the Co₃(Al,Nb,Mo) intermetallic compound with L1₂ crystal structure were found by TEM study.
