The mean C amount on a surface is from 1.20 mass % to 1.50 mass %, and the mean N amount is from 0.10 mass % to 0.60 mass %. Deposits having a particle size of 0.1 μm or more on the surface have a mean particle size of 0.6 μm or less, exist as 700,000 particles or more per mm2, and have an area ratio of 10% or more. The amount of retained austenite of the surface is from 25% to 45% by volume ratio. The hardness of the surface is Hv 750 or more. The inside of the rolling part has an amount of retained austenite of 20% or less by volume ratio.

    摘要: The invention relates to a malleable, high mechanical strength aluminum alloy of the AlMgSi type which can be anodized in a decorative manner, to a semifinished product produced from said alloy, in the shape of strips, sheets or extruded profiles, and to a structural component produced from the above semifinished products, especially a reshaped component that has been anodized in a decorative manner. The invention also relates to a method for producing an aluminum alloy component of the above type. Said aluminum alloy has good malleability, achieved by weight percentages of strontium in the alloy and defined weight ratios of silicon to magnesium and iron to strontium.

    摘要: A method of producing a workpiece of a heat-resistant steel, such as hot forming tool steel, where the workpiece may be hardened and depassivated after mechanical machining and electrochemical treatment. The hardening including a reduction step, so that no depassivation need be performed by pickling, for example, before nitriding. The result of the hardening treatment is a favorable surface condition for stepwise nitriding.

    摘要: A method of nitriding a metal includes transforming a surface region of a generally nitrogen-free metal into a nitrogen-containing solid solution surface region. A first heating process heats the surface region at a first temperature in the presence of a nitrogen gas partial pressure to form a nitrogen-charged surface portion on the surface region. A second heating process heats the surface region and nitrogen-charged surface portion at a second temperature for a predetermined time to interstitially diffuse nitrogen from the nitrogen-charged surface portion a depth into the surface region. Coincident with the second heating process, an ionized inert or reducing gas removes the nitrogen-charged surface portion. The resulting nitrogen-containing solid solution surface region has a gradual transition in nitrogen concentration.

    摘要: A method of producing an oriented oxide superconducting film. A metal oxyfluoride film is provided on a substrate. The metal oxyfluoride film comprises the constituent metallic elements of an oxide superconductor in substantially stoichiometric proportions. The film is then converted into the oxide superconductor in a processing gas having a total pressure less than atmospheric pressure.
