Abstract: A process for producing a galvanneal layer on a steel substrate, including forming a Zn-Fe coating having a predetermined Fe content F (wt. %) on the steel substrate; and heat treating the Zn-Fe coating on the substrate from a predetermined starting temperature T.sub.1 (.degree.C.) to a predetermined ending temperature T.sub.2 (.degree.C.) at a predetermined heating rate R (.degree.C./min.), wherein F, T.sub.1, T.sub.2, and R are selected so that the following condition is met,a.R.sup.2 +b.T.sup.2 +c.R.F.+d.R.T +e.R+f.T=gwhere a, b, c, d, e, f and g are predetermined constants, thereby to form a virtually 100% .delta..sub.1 phase galvanneal structure. Alternatively, the heat treatment can be preformed until the specimen temperature is just below a minimum temperature of the .delta..sub.1 phase stability range at at selected Fe content and heating rate, followed by an isothermal hold for a predetermined time period until transformation to the .delta..sub.1 phase occurs.

Abstract: The invention is directed to a low-silicon, grain oriented electrical steel exhibiting a Goss texture. Compositionally, such steel comprises, by wt. %:C--0.02/0.07Mn--<0.50Si--0.5/2.0S--<0.05Al--0.01/0.5N--0.005/0.03Fe--balance,The texture for such a steel, in the form of sheet or strip, is achieved by a processing sequence which includes among its other steps or features, the provision of a short time transcritical anneal prior to a final cold reduction of the sheet or strip.

Abstract: This invention is directed to a method and to the resulting product, wherein said product is a low-carbon dual phase steel having a combination of high strength, good ductility and a YS/TS ratio .ltoreq.0.6. The method includes the steps of (1) preparing an Al-killed steel consisting essentially of 0.05 to 0.15 wt. % C, up to 2.0 wt. % Mn, up to 1.0 wt. % Si, 0.03 to 0.15 wt. % V and a sufficient amount of titanium to "getter" the excess sulfur and nitrogen, with the balance essentially being iron, where the titanium addition should be at least equal to the atomic percent of the sulfur plus nitrogen, but no more than about 1.6 times, (2) intercritically annealing such steel within the .alpha.+.gamma. temperature range, and (3) cooling to room temperature.
