    Abstract: A process for the production of a steel material comprising rolling a steel material having a structure mainly comprising ferrite or ferrite plus pearlite or ferrite plus cementite at a percentage reduction of area of at least 20 % in a ferrite recrystallization temperature region to achieve such characteristics as a crystal particle diameter of not greater than 3 mu m, preferably not greater than 1 mu m, an elongation of at least 20 %, a value of tensile strength (TS: MPa) x elongation (El: %) of at least 10,000 or a percent ductile fracture of at least 95 %, preferably 100 %, in an actual pipe Charpy impact test at -100 DEG C. Particularly, this process yields a steel material containing 0.05 to 0.30 wt.% of C, 0.01 to 3.0 wt.% of Si, 0.01 to 2.0 wt.% of Mn and 0.001 to 0.10 wt.% of Al and having a structure comprising ferrite alone or ferrite and a second phase, wherein the ferrite particle diameter is not greater than 3 mu m and the areal ratio of the second phase is not greater than 30 %. An untreated steel pipe having the composition described above is heated to (Acl + 50 DEG C) to 400 DEG C and subjected to stretch reduction at a cumulative diameter reduction ratio of at least 20 % in a rolling temperature range of (Acl + 50 DEG C) to 400 DEG C. In this case, the rolling process preferably contains at least one rolling pass having a diameter reduction ratio of at least 6 % in the stretch reduction. When the contents of C, Si, Mn and other alloy elements are kept at low levels and stretch reduction is carried out in the temperature range described above, a steel pipe having high ductility and strength and improved toughness and stress corrosion crack resistance can be manufactured and the resulting pipe can be used as a line pipe. The fatigue resistance can be improved, too.

    Abstract: A thermocouple (10) formed of a length of a single composition having a first solid phase section (12) adjoining a second solid phase section (16), and a transition (14) therebetween. One method of making such thermocouples (10) is to raise the temperature of the first solid phase section (12) above its transformation temperature while maintaining the temperature of the second adjoining solid phase section (16). A second method includes rapidly solidifying a molten material (40) by contacting it with a moving substrate (44) formed of adjoining regions of differing thermal conductivity (48, 46). A third method includes rapidly solidifying a molten material (72) by alternatingly contacting it with a cooling fluid (76) and air. A fourth method includes transforming a section of a length of material in a first solid phase to a second solid phase by mechanical means.

    Abstract: Processes for fabricating components to have two or more regions with different grain structures, and components produced by such processes. The processes entail performing at least one forging step on a preform to produce a profile having at least a first portion corresponding to the first region of the component. The preform is formed of a precipitation-strengthened alloy having a solvus temperature, and the at least one forging step comprises a nonfinal forging step performed at a first strain rate and at a first subsolvus temperature that is below the solvus temperature of the alloy. A subsequent forging step is performed on the profile to produce a final profile comprising the first portion and a second portion corresponding to the second region of the component. The subsequent forging step is performed at a strain rate and at a subsequent subsolvus temperature, wherein at least one of the subsequent strain rate and subsequent subsolvus temperature is either higher or lower than the first strain rate or first subsolvus temperature. A heat treatment is then performed on the final profile to cause grain growth, wherein the first portion of the final profile has a different grain size than the second portion.

    Abstract: A method for making an ordered magnetic alloy includes (a) providing a thermally conductive base having opposite first and second surfaces; (b) forming a thermal barrier layer on the first surface of the thermally conductive base; (c) forming a disordered magnetic alloy layer on the thermal barrier layer, the disordered magnetic alloy layer being made from a disordered alloy which contains a first metal selected from Fe, Co, and Ni, and a second metal selected from Pt and Pd; and (d) after step (c), applying a transient heat to the thermally conductive base to cause rapid thermal expansion of the thermally conductive base, which, in turn, causes generation of an in-plane tensile stress in the disordered magnetic alloy layer.
