High energy X-rays — or HEX rays are very hard X rays, with 80 keV 1000 keV typically one order of magnitude higher in energy than conventional X rays (and well into the gamma ray energies of over 120 keV). They are produced at modern synchrotron radiation sources… … Wikipedia
deformation and flow — Alteration in size or shape of a body under the influence of mechanical forces. Flow is a change in deformation that continues as long as the force is applied. Gases and liquids normally flow relatively freely, while solids deform when subjected… … Universalium

Glass transition temperature — The glass transition temperature, T g, is the temperature at which an amorphous solid, such as glass or a polymer, becomes brittle on cooling, or soft on heating. More specifically, it defines a pseudo second order phase transition in which a… … Wikipedia
Heat deflection temperature — The heat deflection temperature or heat distortion temperature (HDT, HDTUL, or DTUL) is the temperature at which a polymer or plastic sample deforms under a specified load. This property of a given plastic material is applied in many aspects of… … Wikipedia
Operating temperature — An operating temperature is the temperature at which an electrical or mechanical device operates. The device will operate effectively within a specified temperature range which varies based on the device function and application context, and… … Wikipedia
