By using fusion welding to weld AISI 304 austenitic stainless steel (ASS) and commercial copper, the creation of brittle intermetallic in region that compromises strength joints is primary challenge. However, friction a suitable method for joining these two materials because no obvious defects are produced at joints. The joint significantly influenced by friction-welding-process variables inclu...

This work aims to investigate the microstructure and mechanical behavior of dissimilar API X80-AISI 4130 steel welded joints coiled tubing. The at weld interface AISI side results in a relatively lower toughness. HAZ has an obvious coarsening phenomenon. tensile tests show that deformation process joint is mainly controlled by two base materials: beginning X80 its end. Charpy impact toughness c...

An Al-40.0Ge-3.4Si wt.% alloy foil with a thickness of 50 ± 5 μm, obtained via an ultrafast solidification method, is described in this work. A complete wetting the aluminum substrate angle 0° observed, and formation drop 30 5° observed on steel substrate. Similar dissimilar brazed joints AA 6082 stainless-steel AISI 304 are obtained. The microstructure 6082/AA seam homogeneous contains particl...
