Abstract Scope |
Decreasing Mn and increasing Cr in the cast Cantor’s alloys and their MC–strengthened versions may have consequences on the refractoriness and on the high temperature mechanical properties. Differential thermal analysis (DTA) was run to specify the temperatures of starts and stops of melting and solidification. Room temperature Vickers indentations and 3 points flexural creep tests, at several temperatures in the [1,000 – 1,200°C] range for several values of the induced maximal tensile stress varying between 10 and 30 MPa, were carried out. This evidences that no significant modifications on these properties result from the tested changes of the Cr/Mn ratio. This suggests that Cr and Mn can be differently rated to maximize the resistance against hot oxidation without deleterious consequences on the mechanical behavior at high temperature. |
