...Abstract Abstract Dual-phase steels are a new class of high-strength low alloy (HSLA) steels characterized by a microstructure consisting of about 20% hard martensite particles dispersed in a soft ductile ferrite matrix. In addition to high tensile strength, in the range of 550 MPa (80 ksi...

...-strength low-alloy (HSLA) steels achieve their good combination of formability and weldability through microalloying. Advanced high-strength steels (AHSS) such as dual-phase (DP), complex-phase (CP), and transformation-induced plasticity (TRIP) steels show superior strength compared to the HSLA grades...

However, in hypereutectoid steels (above 0.77% C), the annealing takes place above the A 1 temperature, which is the dual-phase austenite-cementite region. Figure 2 shows...

... and reduces the weld size. This, in turn, lowers the load-bearing capability of the weld. Therefore, weld-metal expulsion should be avoided to maintain weld integrity. Figure 13 shows a plot between welding current and the weld sizes for three grades of dual-phase steels. Dual-phase steels are a class...
