Каустический крекинг, русский
Вид корозионного растрескивания под напряжением, с которым наиболее часто сталкиваются в углеродистых сталях или железохромоникелевых сплавах, подвергшихся воздействию концентрированных растворов гидроксида при температурах от 200 до 250 °с (400 до 480 °f). также известно как щелочное растрескивание.

Crack, английский
- Fissure
- Трещина
- A building defect consisting of complete or incomplete separation within a single element or between contiguous elements of constructions. crack-control reinforcement steel reinforcement in concrete construction to prevent cracks or to limit them to small, uniformly distributed ones.
- A thin break there’s a crack in one of the bones in the skull. verb to make a thin break in something, or become split she cracked a bone in her leg. cracked lip a lip where the skin has split because of cold or dryness
- “in a crack,” immediately.
- First-class or excellent (e.g., a crack ship is uncommonly smart in evolutions or discipline).
- Трещина о ~s caused by creep трещинообразование от ползучести; ~s
- Visible breakage of the powder coating, usually caused by insufficient cross-linking
- A snare drum sound in which the sharp attack of the stick on the head of the snare has been boosted for emphasis at around 5 to 10 khz.
- A defect in a woven fabric consisting of an open fillingwise streak extending partly or entirely across the fabric.
- A small, partial or incomplete defect.
- A discontinuity that has a relatively large cross-section in one direction and a small or negligible crosssection when viewed in a direction perpendicular to the first.
- (1) break, fissure, or rupture, sometimes v shaped and relatively narrow and deep. discontinuity that has a relatively large cross section in one direction and a small or negligible cross section when viewed in a direction perpendicular to the first. (2) propagating discontinuity caused by applied stresses such as mechanical flexing (fatigue crack). difficult to detect unaided because of fineness of line and pattern (may have a radial or latticed appearance). crack, fatigue: progressive crack that usually is initiated at a free surface such as a fastener hole and is caused by the repeated mechanical loading and unloading of the object.
- (1) разрыв, трещина или разрыв, иногда v-образной формы, относительно узкий и глубокий. разрыв, который имеет относительно большое поперечное сечение в одном направлении и маленькое или незначительное поперечное сечение, если смотреть в направлении, перпендикулярном первому. (2) распространяющаяся несплошность, вызванная приложенными напряжениями, например, механическим изгибом (усталостная трещина). трудно обнаружить без посторонней помощи из-за тонкости линий и рисунка (может иметь радиальный или решетчатый вид). трещина, усталость: прогрессирующая трещина, которая обычно возникает на свободной поверхности.
- Stress induced break, fissure or rupture, sometimes v shaped in cross section and relatively narrow. by convention, a crack is called linear if it is at least three times longer than it is wide.
- Propagating discontinuity caused by fatigue, corrosion or stresses such as heat treating or grinding. may be difficult to detect unaided because of fineness of line and pattern (may have a radial or latticed appearance).
- (1) stress induced break, fissure or rupture, sometimes v shaped in cross section and relatively narrow. by convention, a crack is called linear if it is at least three times longer than it is wide. (2) propagating discontinuity caused by fatigue, corrosion or stresses such as heat treating or grinding. may be difficult to detect unaided because of fineness of line and pattern (may have a radial or latticed appearance). compare fracture. crack, cold: (1) discontinuity that forms near room temperature while a casting cools due to stresses caused during nonuniform cooling. (2) discontinuity that may form in a weld either as it cools or later, if stress, hydrogen contamination and microstructural conditions allow. crack, crater: multisegment crack in a weld crater. segments radiate from a common point, often called star cracks. crack, fatigue: see fatigue. crack, forging: stress induced discontinuity formed during mechanical shaping of metal; see crack; discontinuity, primary processing. crack, grinding: shallow discontinuity formed in the surface of relatively hard materials because of excessive grinding heat or the brittleness of the material. grinding cracks typically are oriented perpendicular (90 degree rotation) to the direction of the grinding wheel. see also grinding burn. crack, hot: (1) discontinuity formed in a weldment caused by the segregation at grain boundaries of low melting constituents in the weld puddle. (2) postsolidification casting discontinuity caused by internal stresses.

(2) postsolidification casting discontinuity caused by internal stresses. compare crack, cold; hot tear. crack, quenching: rupture produced during quenching of hot metal because of more rapid cooling and contraction of one portion of test object than occurs in adjacent portions.
