fabricating an experimental 13 chromium, 2 aluminum alloy steel into strip first requires compacting gas atomized metal powder into a ring by hot isostatic pressing. thin strip then is produced by peeling - a technique of machining a wide chip off of the outside diameter of the ring. this process and subsequent annealing are described with reference to surface finish and microstructures fabrication of strip by hot isostatic pressing gas atomized powder into large rings and peeling into strip can be a flexible and efficient method of producing strip up to 160mm. (6. 2 in. ) wide and 200 microns thick, provided: (1) the alloy is readily machinable; (2) microstructures are well controlled; and (3) the material is free of voids and non-metallic inclusions. the advantage of using gas atomized/hot isostatically pressed material is that it can produce thin strip that is free of macrosegregation and consistent in properties. 12 refs
