  • Patent number: 8492005
    Abstract: In joining a magnesium alloy material 1 (first material) and a steel material (second material), a zinc-plated steel plate 2 plated with zinc (metal C) is used as a steel material, Al (metal D) is added to the magnesium alloy material 1. Next, eutectic melting of Mg and Zn is caused so as to remove a product produced by the eutectic melting with an oxide film 1f and impurities from a joint interface. Moreover, an Al—Mg system intermetallic compound such as Al3Mg2 and an Fe—Al system intermetallic compound such as FeAl3 are produced, whereby regenerated surfaces of both materials 1 and 2 are joined via a compound layer 3 containing those intermetallic compounds.

  • Publication number: 20130095345
    Abstract: In conventional Al coated steel sheet, with the Al coating as it is, black discoloration cannot be prevented at 550° C. or more. For this reason, post annealing is used to form a barrier layer and suppress the formation of Fe—Al intermetallic compounds. However, with this method, there were the problems that the steel sheet became poor in workability and, further, high temperature, long time heating was required, so there were problems from the workability, economy, and environmental aspect. The present invention provides steel sheet which has a heat black discoloration resistance even at a 550° C. or more high temperature without additional annealing after Al coating and further is excellent in workability. That is, it is hot dip Al coated steel sheet which comprises steel sheet which contains predetermined ingredients of C, Si, P, S, Al, N, and O plus one or both of furthermore Ni: 0.01 to 0.1% or Cu: 0.01 to 0.1% and satisfies 10×C+Ni+Cu>0.

  • Publication number: 20110300407
    Abstract: Provided are a coated steel sheet, a hot press formed product using the steel sheet, and a producing method thereof. Conditions for hot-dip coating bath are optimized when an aluminum-coated steel sheet is produced using a hot rolled steel sheet or a cold rolled steel sheet, and processes are controlled during production of a hot press formed product from the steel sheet, thereby forming a coating layer having a high ratio of (Fe3Al+FeAl) compound layer on the surface of the steel sheet. In cases where the (Fe3Al+FeAl) compound layer has an appropriate occupancy ratio with respect to the whole thickness of the coating layer, good resistance against crack and corrosion can be achieved to improve a local corrosion resistance of the hot press formed product, particularly, a pitting corrosion resistance. Therefore, high-quality hot press formed products can be produced with high productivity and lower costs.
