Effect of microstructure on mechanical properties of refractory Co-Cr-W-Ni alloy

Effect of microstructure on mechanical properties of refractory Co-Cr-W-Ni alloy

A cobalt-base refractory alloy containing W, Ni, and Cr, which is widely used for making spacecraft components operating at high temperatures, is studied. Changes in the microstructure of the alloy are studied depending on the heat treatment, and the effect of these changes on mechanical properties...

Beschreibung
Zusammenfassung:A cobalt-base refractory alloy containing W, Ni, and Cr, which is widely used for making spacecraft components operating at high temperatures, is studied. Changes in the microstructure of the alloy are studied depending on the heat treatment, and the effect of these changes on mechanical properties at room and high temperatures is determined.
