maragingn.

Brit.

/ˈmɑːreɪdʒɪŋ/, U.S.

/ˈmɑrˌeɪdʒɪŋ/

Forms: 1900s– marageing, 1900s– maraging, 1900s– mar-aging.

Origin: Formed within English, by compounding. Etymons: martensite n., ageing n.

Etymology: < mar- (in martensite n.) + ageing n., probably after earlier martempering n. Compare maraged adj.

Metallurgy.

A process for strengthening steel alloys involving slow cooling that results in the transformation of austenite to martensite and subsequent age hardening of the martensite.

1961 Inco Nickel Topics 14 iv. 8/1 The new steel develops its high strength..by means of a remarkably easy heat treatment involving age-hardening of martensite. This treatment has been given the abbreviated designation of ‘mar-aging’.

1961 Iron Age 16 Nov. 110/1 The maraging discovery, made at the company's Bayonne, N.J. research lab, paves the way for a new family of steels.

1970 McGraw-Hill Yearbk. Sci. & Technol. 348/2 Hardening by maraging does not produce distortion or surface softening..so that no machining is necessary after hardening.

Compounds

maraging alloy n. = maraging steel n.

1968 R. Kumar Physical Metall. Iron & Steel xi. 292 In marageing alloys, the role of interstitial carbon in raising the strength of steel is taken over by substantial amounts of nickel, cobalt, and molybdenum.

maraging steel n. steel that has been or may be hardened by maraging, generally containing up to 25 per cent nickel and smaller amounts of titanium, cobalt, molybdenum, or other elements.
