Abstract
A process for manufacturing a structural element with brazed-on, bent or folded metal foil components having a foil thickness of less than 500 .mu.m, made of an ODS sintered ferrous material. The sintered material is manufactured by mechanically alloying the basic powders, hot pressing and/or extruding, and subsequently hot-rolling, cold-rolling and final recrystalization annealing to form the sintered material into a foil having improved mechanical strength properties. After the cold-rolling step, the foil material is annealed so that the foil may be thereafter bent and folded at room temperature. The bent and/or folded foil is recrystallization-annealed at a temperature between 1100.degree. and 1300.degree. C. during 3-600 minutes, simultaneously with a brazing operation, in a single process step.
