E. Dieter Mech. Metall. v. 146 Quench hardening results in an increase in yield stress and a decrease in the rate of strain hardening. 2000 Science 12 May 994/1 The actual mechanism of the quench hardening of steel..was hotly debated even in the early 20th century.

Soc. 62 2166/1 At suitable intervals..metaphosphoric acid was added to quench the reaction, and the samples were titrated. 1978 G. C. Hill & J. S. Holman Chem. in Context xxiii. 355 Portions of the reaction mixture can be pipetted into sodium hydrogencarbonate solution which ‘quenches’ the reaction by neutralising the acid catalyst. 1990 Nucleic Acids Res. 18 379/1 The reactions are quenched directly by the pyrrolidine cleavage solution, instead of by ethanol precipitation. f. transitive. Electronics. To prevent (the discharge in a radiation counter, or the resulting current) from continuing too long, so that the device is free to register another event. Hence: to design (a counter) so as to achieve this. ΘΚΠ the world > matter > physics > atomic nucleus > measurement of ionizing radiation > restrict discharge [verb (transitive)] quench1940 1940 Physical Rev. 57 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. 1942 E. C. Pollard & W. L. Davidson Appl. Nucl. Physics iii. 30 A very common device to quench a counter is to employ a vacuum tube. 1958 O. 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. 1992 Microelectronic Engin. 19 62 The avalanche current flows until an external circuit quenches the avalanche by lowering the bias voltage. 9. intransitive. Physics, Electronics, etc. To undergo quenching (in various senses); to be suppressed, to die away; spec. (of a material) to change from a superconducting state to a non-superconducting state. ΘΚΠ the world > matter > physics > solid state physics > superconductivity > change to non-superconducting state [verb (transitive)] quench1945 1945 Electronics Mar. 101 By high concentration of power, work rapidly heats and quenches with practically no distortion or scale formation. 1969 Sci. Jrnl. Apr. 42/2 Increasing current is passed through the superconductor until the material ‘quenches’ (goes normal). 1975 Physics 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). 1980 Internat. Jrnl. Biochem. 12 1020 (table) The fluorescence quenches slowly, indicating large amounts of stored porphyrins. 1995 Focus Aug. 24 (caption) The flash ‘quenches’ before the shutter closes again, the instant the correct exposure is made. 2001 Jrnl. Appl. Physics 90 2314/2 With the increase in temperature, the output from ZnS-based blue and green laser diodes quenches quickly.
