Abstract: A magnetic recording film having high magnetic remanence and unusually good square loop characteristics at thicknesses of between one and five microinches can be deposited directly on non-magnetic electroless nickel from an electroless bath containing cobalt ions, citrate ions, hypophosphite ions, phosphate ions and, if desired, nickel ions. The electroless bath may also contain an ethanolamine, or mixture thereof, as a wetting agent and brightener. The coercive force of the magnetic recording film can be selected to lie between 300 and 1,000 oersteds by adjusting the pH of the bath. Thicker structures with good square loop characteristics and high coercive force can be prepared by the successive plating of two or more magnetic thin films separated by thin films of non-magnetic nickel-phosphorus.

The ductile foil permits fabrication of preforms of complex shapes which do not require binders and/or fluxes necessary for brazing powders presently used to braze stainless steels and nickel base alloys.

Thermal strains caused by a temperature differential between the inner and outer layers are taken up without harmful effect by the intermediate low modulus layer.

Abstract: High strength low alloy steels, produced as strip or the like by hot rolling, permit unusual economy of alloying ingredients while achieving superior mechanical properties, with a composition containing specifically low carbon and low manganese, and moderate proportions of both columbium and titanium, preferably with no requirement of silicon. Yield strengths in a range to and well above 80 ksi are attainable depending on the content of columbium and titanium, and good properties of formability are exhibited in the transverse direction. Processing conditions, for hot rolling and coiling, can be selected over reasonably convenient ranges of temperature conditions, while rolling load requirements are acceptable for products of various thicknesses. The steels are notably useful for thin strip, satisfying the usual mechanical property needs of such products with relatively low cost.
