Abstract: An aluminum-alloy-clad plate which includes a plurality of superposed aluminum alloy layers and which has undergone a diffusion heat treatment. Aluminum alloy layers having specific compositions are superposed so that any adjoining two of these differ in the content of Mg or Zn, and are subjected to a diffusion heat treatment to give a structure which has fine crystal grain diameters and Mg/Zn mutual diffusion regions and which has specific DSC properties. Thus, both higher strength and high formability are imparted.

Abstract: A method which allows process-stable hot-dip coating of Ni-alloy steel flat products in a cost- and resource-effective manner, including the following steps: a) provision of a steel flat product obtained by cold- or hot-rolling; b) within 1-30 s, heating the steel flat product to a holding temperature between 700 and 1100° C., under a heating atmosphere of N2; c) holding the steel flat product at the holding temperature for a holding duration of 10-120 s under a holding atmosphere of N2; d) cooling the steel flat product from the holding temperature to a strip inlet temperature of 430-800° C.; and e) passing the steel flat product through an inlet zone, in which an inert or reducing inlet atmosphere predominates, and passing the steel flat product through a melt bath, wherein TP1>TP2>TP4.

Abstract: New methods for aging aluminum alloys having zinc and magnesium are disclosed. The methods may include first aging the aluminum alloy at a first temperature of from about 310° F. to 530° F. and for a first aging time of from 1 minute to 6 hours, and then second aging the aluminum alloy at a second temperature for a second aging time of at least 30 minutes, with the second temperature being lower than the first temperature.
