▪ I. quench, n.

Franklin in Crawford & Slifkin Point Defects in Solids I. i. 33 The special property of ductility possessed by many metals allows thin wires to be drawn, which may be very rapidly quenched, at maximum cooling rates of 105 deg/sec or higher. With such rapid quenches, one may hope to retain the equilibrium defects present at the high quench temperature.
2. Electronics. The process of stopping an oscillation, esp. in a superregenerative receiver; a signal used for this. Freq. attrib., as quench frequency, the frequency with which oscillations are stopped.

d. Radio. To cause (the spark in a spark transmitter) to cease by mechanical means, so that the secondary (aerial) circuit is no longer coupled to the primary; hence, to stop (oscillation).
1910G. W. Pierce Princ. Wireless Telegr. xxiii. 267 The spark is quenched when the energy in the primary attains its first minimum. 1913Chambers's Jrnl.

Brown Elements of Radio Communication iv. 53 The spark is produced between projecting studs on a rapidly revolving metal disc and two fixed electrodes... The rotation of the disc will rapidly increase the distance between the studs and the electrodes, so that the spark is quenched and the oscillation in the primary circuit ceases. 1938Proc. IRE XXVI. 76 In a typical superregenerative receiver the regenerative coupling between the plate and grid circuits of the detector tube is great enough so that self-sustained oscillations are produced, and these oscillations are periodically quenched, by applying..an alternating voltage having a frequency much lower than that of the oscillations. 1959G. Troup Masers vii. 117 These authors measured the noise figure of an ammonia maser amplifier operated superregeneratively: that is, oscillations were allowed to build up and then quenched. 1966McGraw-Hill Encycl.

d. Physics. To suppress (luminescence); hence, to de-excite (an atom that would otherwise give rise to this effect).
1928Proc. Nat. Acad. Sci. XIV. 851 The results show that hydrogen quenches the resonance radiation of cadmium as effectively as it does that of mercury. 1932Jrnl. Amer. Chem. Soc. LIV. 572 The apparent decrease in quenching at high pressures or temperatures does not at all preclude the possibility that some fraction of the mercury atoms are being quenched to the normal state. 1954C. Zwikker Physical Properties of Solid Materials xiii. 230 Fluorescence may be quenched by radiation, e.g. infra-red of too long a wavelength to excite fluorescence. The quenching photons raise electrons from the crystal lattice..to the copper ions..and thus inhibit the recombination effect. 1976Sci. Amer.

Inorg. Chem. xxiv. 508 The electric fields of other atoms, ions, and molecules surrounding the metal ion in its compounds interfere with the orbital motion of the electrons so that the orbital angular momentum and hence the orbital moment are wholly or partially ‘quenched’. 1971J.

1940Physical Rev. LVII. 1036/1 If we merely assure ourselves that the counter wire is falling somewhat below the starting potential with each discharge, then we can be sure that the discharge is quenched after the first stage and we will have a clean, fast pulse. 1942Pollard & Davidson Applied Nucl. Physics iii. 30 A very common device to quench a counter is to employ a vacuum tube. 1958O. R. Frisch Nucl. Handbk. xv. 14 The discriminator circuit used with Geiger counters..should provide facilities for quenching the counter for a period of several hundred microseconds after each pulse. 1963W. E. Burcham Nuclear Physics vi. 218 It is the function of the alcohol in the gas filling to ‘quench’ the discharge. 1975K. H. Goulding in Williams & Wilson Biologist's Guide to Princ. & Techniques Pract.

7. Physics. To change from the superconducting state to the non-superconducting state.
1969Sci. Jrnl. Apr. 42/2 Increasing current is passed through the superconductor until the material ‘quenches’ (goes normal). 1975Physics Bull. May 214/1 The normal metal (copper or combinations of copper and cupro⁓nickel) is still required to protect the conductor when it reaches the limit of its current carrying capacity and ‘quenches’ (ie undergoes a transition to the normal state).
III. 8. Combs. (from sense 2 b): quench-ageing, changes in the properties of steel, notably hardening, which occur after the metal has been quenched from a high temperature (see quot. 1968); quench-cracking, fracture of a metal caused by thermal stresses during rapid cooling; quench-hardening, hardening of steel by heating it above a critical temperature for some time, quenching rapidly, and then allowing further slow cooling; also = quench-ageing above; so quench-harden v. trans.
1935Trans. Amer. Soc. Metals XXIII. 1049 To one of the three most important examples of aging, found in practically all soft steels, the designation ‘Carbonizing’ has been given for purposes of this discussion. It has also been called ‘sub-critical quench-aging’. 1938Jrnl. Iron & Steel Inst. CXXXVIII. 247p The usual theory put forward to explain the process of quench-ageing, whether in steel or in any other age-hardening alloy, is that it is caused by the precipitation from super-saturated solid solution of particles of the solute in a highly dispersed form on the lattice of the solvent,..preliminary to precipitation. 1961G. E. Dieter Mech. Metallurgy v. 137 Quench aging is a type of true precipitation hardening that occurs on quenching from the temperature of maximum solubility of carbon and nitrogen in ferrite. 1968E. R. Petty Physical Metall. of Engin. Materials v. 92 These changes involve an increase in hardness, elastic limit and tensile strength, accompanied by a fall in ductility and impact resistance, and may occur in low carbon steels finished by rapid cooling from a softening temperature above 600°C or by cold working. In the former case the phenomenon is referred to as quench ageing while the latter is known as strain ageing. 1971Engineering Apr. 20/1 The absence of the defects of material or liquation on the surface of the pins and journals is of particular importance..where these areas are to be hardened by flame or induction, as the risk of quench cracking is almost entirely eliminated. 1973J. G. Tweeddale Materials Technol. I. vi. 172 There is usually a limiting rate of cooling from the outside for any given steel, beyond which it is impractical to go because too-rapid contraction from the outside may cause quench-cracking.
1934H. O'Neill Hardness of Metals & its Measurement vi. 201 Mehl..has reported that quench-hardening a pearlitic steel does not alter its compressibility. Ibid. 202 Ordinary quench-hardening practice by continuous rapid cooling to room temperatures will produce martensite if the rate is sufficient to preserve austenite down to Ar{pp}. 1961G. E. Dieter Mech. Metallurgy v. 146 Quench hardening results in an increase in yield stress and a decrease in the rate of strain hardening. 1969D. K. Allen Metallurgy Theory & Pract. vii. 194/2 Most all carbon steels can be quench-hardened but the hardness does not become appreciable until the carbon content..reaches about 0·35 percent. Ibid. 196/2 The second requirement for quench hardening is that the steel be heated to the recommended hardening temperature and held for a sufficient length of time to allow the steel to become fully austenitized.
