摘要：
Phase-dependent tensile properties of 9Cr-1Mo(V, Nb) ferritic/martensitic steel were evaluated in the temperature range 300 K to 1073 K (27 °C to 800 °C) to quantify differences in the tensile behavior of different phases of this material. The results showed considerable difference in the tensile properties such as yield strength, ultimate tensile strength, and elongation of the three phases of this material—tempered martensite, metastable austenite, and martensite—which can exist at a common temperature. This has been discussed on the basis of structural hysteresis in this material when subjected to thermal cycles causing excursions across various phase fields.
