annealとは意味・読み方・使い方

語源

From Middle English anelen, onelen, from 古期英語 anǣlan, onǣlan (“to burn, ignite, set fire to, consume, heat, enlighten, incite, inflame, inspire, kindle”), from Proto-Germanic *ana (“on”) + Proto-Germanic *ailijaną (“to burn”), from Proto-Indo-European *h₂eydʰ- (“to burn”).

動詞

anneal (三人称単数 現在形 anneals, 現在分詞 annealing, 過去形および過去分詞形 annealed)

1. (metallurgy) To subject to great heat and then (often slow) cooling, and sometimes reheating and further cooling, for the purpose of rendering less brittle; to temper; to toughen.
   • 1812 March 7, O. E., “The Process of Making Iron Wire”, in H[ezekiah] Niles, editor, The Weekly Register, volume II, number 27, Baltimore, Md.: Printed and published by the editor, at the Franklin Press, South-Street, next door to the Merchants' Coffee-House, OCLC 472971892, page 9:

     The best tough soft iron, such as will weld round, is drawn into rods by smiths, using charcoal fires, and taking welding heats every time, the rod is about 1.4 inch diameter, 9 or 10 feet long, containing 4lbs. each, tapered at each end to a long point; they are first anealed by being brought to a bright red heat, in a furnace excluding the air as much as possible, for if the air can be entirely excluded, no scab will rise in anealing; […]

Barus; V[incenc] Strouhal, “The Effect of Sudden Cooling Exhibited by Glass and by Steel, Considered both Physically and Chemically”, in Report of Work Done in the Division of Chemistry and Physics Mainly During the Fiscal Year 1885–'86 (Bulletins of the United States Geological Survey; no. 42; 50th Congress, 2d session, House of Representatives Miscellaneous Documents; no. 137), volume VII, Washington, D.C.: Government Printing Office, published 1889, OCLC 881832145, page 123:

     On closer inspection it appeared that steel annealed at 100° is, cæteris paribus, more easily soluble than glass hard steel; steel annealed at 200° more easily soluble than steel annealed at 100°, and steel annealed at 360° more easily soluble than steel annealed at 200°. […] These curious results were substantiated by annealing one-half of short glass hard rods (ca. 5^cm in length) at red heat on dissolving in HCl, the diameter of the soft length is diminished more rapidly than the diameter of the hard length.

     The isolated disordered regions and the amorphous layer have widely different anneal behavior. In the case of germanium and silicon, the isolated disordered regions anneal at moderate temperatures of approximately 200° and 300° C, respectively. The amorphous layers also anneal in a characteristic fashion, but at appreciably higher temperatures, i.e., at approximately 600° C in silicon and 400° C in germanium. It should be noted that even though both types of disorder can be annealed at temperatures well below those where diffusion of the dopant species occurs, there are still defects present.

   • 1979, J.G. Ballard, The Unlimited Dream Company, chapter 30:

     I felt his strong bones anneal themselves to my own, his blood vent its bright tide into my veins, the semen of his testicles foam as it dashed in a torrent against mine.

     A properly made, fully sintered and fully annealed metal clay piece should be able to stand up to any traditional metalsmithing technique.

2. To cool glass slowly, to minimize internal stress.
3. (archaic) To burn colors onto a glass or other surface.

     It was customary to beautify the Prow with Gold, and various ſorts of Paint and Colours: […] Several other Colours were alſo made uſe of, nor were they barely varniſh'd over with them, but very often anneal'd by Wax melted in the Fire, ſo as neither the Sun, Winds, or Water were able to deface them.

     Such were the features of her heavenly Face, / Her limbs were form'd with ſuch harmonious grace: / So faultleſs was the frame, as if the whole / Had been an emanation of the ſoul; / Which her own inward ſymmetry reveal'd; / And like a picture ſhone, in glaſs anneal'd.

     In contrast, our work showed that the 100% hydrogen anneal (1160°C for 45 min) led to a defect-free, atomically smooth surface. It should be noted that a high temperature anneal in Ar, H₂, or high vacuum is a well established pre-epitaxial growth step by which a native oxide film is removed to obtain a good quality epitaxial layer […].

     In the two-step anneal, the low temperature (nucleation) anneal was conducted at 450°C, 650°C, 750°C, or 850°C for various times. Following the low temperature anneal, the samples were heat treated at 1000°C for a total cumulative anneal time of 40 h. All anneals were carried out in a dry nitrogen ambient environment.
