Abstract
868,140. Making sheet; altering molecular structure. VEREINIGTE DEUTSCHE METALLWERKE A.G. Dec. 9, 1957, No. 38251/57. Classes 83 (2) and 83 (4). A method of producing a pronounced cubic texture in high grade magnetizable strip or sheet consisting of iron alloys containing between 0.5 and 2.5% silicon or between 0.5 and 2% aluminium, or a total content of 5.0mm aluminium and silicon of between 0.5 and 2.5%, in which the hot-rolled strip is, if necessary, heat treated, cold rolled in one or more stages with intermediate anneals, and finally subjected to a recrystallization anneal, is characterized in that the reduction of the sheet or strip by cold rolling is between 70 and 90% if a single stage is employed, or if cold rolling is carried out in two or more stages that the penultimate cold-rolling stage produces a reduction of between 75 and 90%, and wherein the number of passes in the last or penultimate cold-rolling stage is selected to be not more than 10 and the material is aged after the cold rolling and before it is subjected to the final recrystallization anneal at, e.g. 1200‹ C. The ageing is effected either at room temperature for 2 to 10 days and at 100‹ C. for 1 to 10 hours, or at elevated temperatures not exceeding 300‹ C. If ageing is not carried out immediately after cold rolling or immediately before the final heat treatment begins the strip or sheet is maintained at a temperature of 0‹ C. or less. Alternatively, after the cold rolling, the sheet or strip is stored for 2 to 10 days at a temperature between 35‹ and 20‹ C. and then subjected to the final heat treated. Specification 442,211 is referred to.
