Aging 1 |
(english) A change in the properties of certain metal and alloys (such as steel) that occurs at ambient or moderately elevated temperatures after a hot working heat treatment or cold working operation. Typical properties impacted are hardness, yield strength, tensile strength, ductility, impact value, formability, magnetic properties, etc. See also Non-aging. |
Aging 2 |
(english) A change in properties that occurs at ambient or moderately elevated temperatures after hot working or a heat treating operation (quench aging in ferrous alloys), or after a cold working operation (strain aging). The change in properties is often, but not always, due to a phase change (precipitation), but does not involve a change in chemical composition. In a metal or alloy, a change in properties that generally occurs slowly at room temperature and more rapidly at higher temperatures. |
AIR BLEEDER AUTOMATIC |
(english) A valve that is fit into a hydraulic pipeline to facilitate automatic release of air trapped in the pipeline. See also AIR BLEEDER, MANUAL. |
Ball Piston Pumps |
(english) The Ball Piston Pump is a very simple pump design. It has a rotor which revolves around an internal stator. The rotor has twelve cylinders machined out of it, and each cylinder has a ball inside which can slide in and out of the cylinder. |
