    Abstract: An ultrahigh carbon steel having a composition of carbon in an amount of from about 0.8 weight percent up to the maximum solubility limit of carbon in austenite, aluminum in an amount of from about 0.5 to about 10 weight percent, an effective amount of a stabilizing element acting to stabilize iron carbide against graphitization, and the balance iron. Preferably, the aluminum is present in an amount of from about 0.5 to about 6.4 weight percent and the stabilizing element is chromium. The steel has excellent ductility and is readily hot, warm and cold worked without cracking. It is particularly useful in superplastic forming operations, and may be processed to a suitable microstructure by any technique which reduces its grain size to about 10 microns or less, and preferably to about 1 micron. Such a very fine grain size is readily achieved with the steel, and the aluminum and stabilizing additions act to retain the fine grain size during superplastic processing.

    Abstract: The invention relates to a method for manufacturing a ferritic-austenitic stainless steel having good formability and high elongation. The stainless steel is heat treated so that the microstructure of the stainless steel contains 45-75% austenite in the heat treated condition, the remaining microstructure being ferrite, and the measured Md30 temperature of the stainless steel is adjusted between 0 and 50° C. in order to utilize the transformation induced plasticity (TRIP) for improving the formability of the stainless steel.

    Abstract: The invention relates to foundry engineering, more specifically to producing an antifriction layer of a plain bearing by casting babbitt into a bearing shell or backing and is applicable to the manufacture and renewal of plain bearings.
    The invention is aimed at improving the quality of a plain bearing antifriction layer.
    A method for producing an antifriction layer of a plain bearing including: casting babbitt into a bearing shell or backing and forcedly cooling the babbitt at a speed providing structural uniformity of the antifriction layer, mainly by cooling babbitt on the cast-in layer side, characterized in that said casting of babbitt into a bearing shell or backing produces a semifinished antifriction layer which is subjected to plastic deformation by means of a punch under superplasticity conditions to produce an antifriction layer, the bearing shell or backing being used as a die.
