11Work hardening — Work hardening, also known as strain hardening or cold working, is the strengthening of a metal by plastic deformation. This strengthening occurs because of dislocation movements within the crystal structure of the material.[1] Any material with… …
12Cryogenic hardening — is a cryogenic heat treating process where the material is cooled to approximately −185 °C (−301 °F), usually using liquid nitrogen. It can have a profound effect on the mechanical properties of certain steels, provided their composition and …
13Shock hardening — is a process used to strengthen metals and alloys, wherein a shock wave produces atomic scale defects in the material s crystalline structure. As in cold work, these defects interfere with the normal processes by which metallic materials yield… …
14surface hardening — ▪ metallurgy treatment of steel by heat or mechanical means to increase the hardness of the outer surface while the core remains relatively soft. The combination of a hard surface and a soft interior is greatly valued in modern engineering… …
15Gas dynamic cold spray — is a coating deposition method developed in the mid 1980s in the Soviet Union in The Institute of Theoretical and Applied Mechanics by Papyrin and his team. The solid powders (1 to 50 micrometers in diameter) are accelerated in supersonic gas… …
16Hammer hardening — Hammer Ham mer (h[a^]m m[ e]r), n. [OE. hamer, AS. hamer, hamor; akin to D. hamer, G. & Dan. hammer, Sw. hammare, Icel. hamarr, hammer, crag, and perh. to Gr. a kmwn anvil, Skr. a[,c]man stone.] 1. An instrument for driving nails, beating metals …
17Self-hardening — Self hard en*ing, a. (Metal.) Designating, or pert. to, any of various steels that harden when heated to above a red heat and cooled in air, usually in a blast of cold air with moderate rapidity, without quenching. Such steels are alloys of iron… …
18strain-hardening — /streɪn ˈhadnɪŋ/ (say strayn hahdning) noun an increase in the hardness of a metal resulting from the permanent change to its crystalline structure caused by cold working. Also, work hardening. –strain hardened, adjective …
19work-hardening — noun Metallurgy toughen (a metal) as a result of cold working. → work harden …
20холоднотвердеющие смеси (ХТС) — [cold hardening mixtures] смеси, твердеющие на воздухе, в оснастке или вне ее под действием газообразных, порошкообразных, жидких отвердителей или катализаторов (Смотри Связующие материалы). Смотри также: Смеси формовочные смеси …
