Aluminum Base

Dissimilar metals joints between aluminum and zinc-coated steel were joined by CMT machine with ER4043 filler metal. The microstructure and mechanical properties of the joints obtained with different heat input were analyzed. The results showed that the thickness of interfacial intermetallic compound was determined by the welding heat input. Tensile specimens were broken in HAZ of aluminum base metal and the tensile strength of the joint can reach 122.3MPa.

Martensite Structure

Microstructure and mechanical properties of medium-Mn steel (Fe–0.14C–5Mn–1Al–Ce) processed by different austenite reverted transformation-annealing temperatures vary from 580 °C to 740 °C were studied. It was found that the austenite reverted transformation-annealing temperature has a strong effect on microstructure evolution. The martensite structure was transformed into austenite by austenite reverted transformation during the austenite reverted transformation-annealing process. The orientation relationship between the austenite and the matrix was dominated by the Kennicutt–Schmidt relation. With the increase of the austenite reverted transformation-annealing temperature, the content of retained austenite first increases and then decreases at room temperature. The tensile strength first decreases and then increases, while the elongation first increases and then decreases. An excellent combination of tensile strength and elongation (Rm × A) was obtained in the Fe–0.14C–5Mn–1Al–Ce steel by austenite reverted transformation-annealing at 640 °C.
