| Abstract Scope |
Dual-phase (ferrite and martensite) steel is widely used in automotive frame structures due to its high strength, toughness, weldability, and low cost. There are substantial reports on the mechanical properties of austenitic steels, as well as work on ferritic steel properties are cryogenic temperatures, but much less on the duplex steels. In this work, we conducted tensile tests on a particular dual-phase steel at cryogenic temperatures. We performed tensile tests at 77 K and compared the results to those at room temperature. We measured yield stress, ultimate tensile strength, and Young’s modulus. Results, comparison of cryogenic and ambient measured properties, and implications for applications are discussed. |
