Fracture test
| Глоссарий в области цветной металлургии |
Breaking a specimen and examining the fractured surface with the unaided eye or with a lowpower microscope to determine such things as composition, grain size, case depth, soundness, or presence of defects.

Испытание на излом, русский
Испытание, при котором образец сломан, и поверхность излома исследована невооруженным глазом или с микроскопом малой мощности, чтобы определить такие факторы как состав, размер зерна, толщину цементированного слоя.

Fracture, английский
- Fractura
- A crack in an ophthalmic lens surface.
- A break in a bone rib fracture or fracture of a rib
- A chip or break on a diamond that is not in the direction of a cleavage plane. irregular in shape they usually appear step-like.
- To break.
- The manner of breaking and the appearance of a mineral or rock when broken along planes other than cleavage, joint, or bedding.
- Трещина; разрушение; разлом; излом; разрыв о ~ at low stresses разрушение [разрыв] (образца) при низких напряжениях
- A general term used in geology for all kinds of discontinuities
- A break, rupture, or crack large enough to cause a full or partial partition of a casting.
- Break, rupture, or crack large enough to cause a full or partial separation. compare crack.

Fracture filling, английский
A diamond enhancement process whereby a cavity or opening in a diamond is filled with an artificial substance.
Fracture grain size, английский

Fracture strength, английский
Fracture stress, английский
- The maximum principal true stress at fracture. usually refers to unnotched tensile specimens.
- The (hypothetical) true stress which will cause fracture without further deformation at any given strain.
Fracture surface markings, английский
Fracture system, английский
Fracture toughness, английский
A measure of a member’s ability to absorb energy without fracture.
Fracture trans, английский
A fracture where the bone is broken straight across
Microscope, английский
- Microscopio
- A scientific instrument with lenses, which makes very small objects appear larger the tissue was examined under the microscope. under the microscope it was possible to see the cancer cells. comment: in an ordinary or light microscope the image is magnified by lenses. in an electron microscope the lenses are electromagnets and a beam of electrons is used instead of light, thereby achieving much greater magnifications.
- Device used to form a highly magnified image of tiny objects for clear visualization
- Instrument that provides enlarged images of small objects. microscope, compound: conventional microscope, using geometrical optics for magnification. also called laboratory microscope. microscope, interference: magnifier using the wavelength of light as a unit of measure for surface contour and other characteristics. microscope, metallographic: metallurgical microscope incorporating a camera. also called a metallograph. most metallographic microscopes share these features: (a) stand with concealed shock absorbers, (b) intense light source, (c) inverted stand so that the test object is face down, (d) viewing screens for prolonged tasks such as dirt count or grain size measurements, (e) bright, dark and polarized illumination options. microscope, metallurgical: microscope designed with features suited for metallography. microscope, phase contrast: laboratory microscope with two additional optical elements to transmit both diffracted and undiffracted light, revealing refractive index discontinuities in a completely transparent test object. microscope, polarizing: microscope with polarizing elements to restrict light vibration to a single plane for studying material with directional optical properties. as fibers, crystals, sheet plastic and materials under strain are rotated between crossed polarizers on the microscope stage, they change color and intensity in a way that is related to their directional properties. mig welding: see gas metal arc welding.
- Instrument that provides enlarged images of very small objects.
Composition, английский
- Состав
- A photographic process in which patterns on two separate substrates are
- The arrangement of subject matter, graphic elements, tones, and light in a scene. can be harmonious or discordant, depending on the photographer, his or her mood, and the subject at hand. there are no set rules, just suggestions; successful compositions are ones that best express particular feelings about the subject or scene.
- N словосложение; образование (ант. decomposition) polysynthetic ~ полисинтетическое объедине- ние
- A composition is a function or relationship that can be constructed from other functions or relationships. for example, the function grandparent(x) is a recursive composition of the parent() function, grandparent(x) = parent(parent(x)). compositional rule of inference (cri) see: fuzzy associative memory. computer-aided design (cad) the process of using a computer to aid in the design and (cadcam) manufacture of objects or systems. the complexity of these systems range from basic drawing systems through systems that can warn you about basic dimensional constraints to systems that understand and implement constraints based on other properties of the objects in the system. it is used for the design of mechanical, electronic, construction, and other systems. computer-aided education the use of computers to aid in the education of personnel. computer-aided instruction, intelligent see: intelligent computer-aided instruction. computer integrated manufacturing (cim) computer integrated manufacturing refers to the integration of computer sensors and controllers into a manufacturing process. this includes three types of functions. first the computers provide programmable and flexible automation of the manufacturing process. this leads to the ability to optimize the process flexibly to react to current variations in the process. finally, the various sensors and controllers can be integrated into a comprehensive system.
- A whole-part relationship in which the life cycle of the part object is dependent on the life cycle of the whole object.
- An activity flow created from multiple actions. composition is core to the human workflow services system.
- An export format that flattens a group of images defined in a deep zoom composer project into a single high-resolution image that is generated at export.
- One or more images that are positioned, arranged, ordered, and proportionally resized according to a user’s specifications within a deep zoom composer project.
- Voluntary arrangement to restructure a firm`s debt, under which payment is reduced.
