White etching cracks (WEC), or white structure flaking or brittle flaking, is a type of rolling contact fatigue (RCF) damage that can occur in bearing steels under certain conditions, such as hydrogen embrittlement, high stress, inadequate lubrication, and high temperature. WEC is characterised by the presence of white areas of microstructural ...
SKIDROW is a well-known cracking group originally formed in 1990, cracking games for the Amiga platform, and having used the motto "Twice the Fun - Double the Trouble!" since then. since then. A piece of cracktro software released by SKIDROW in 1992 with the game 10 Pinball Fantasies contained a complete list of their membership at the time. [ 73 ]
Empress (sometimes stylized EMPRESS) is a video game cracker who specializes in breaking anti-piracy software. While the true identity of Empress is unknown, she refers to herself as a young Russian woman. [1] [2] Empress has also released cracked games under the moniker C000005. [3] Empress is known as one of the few crackers who can crack Denuvo.
Crack in a hardened steel due to hydrogen, observed by scanning electron microscopy (SEM).. Hydrogen embrittlement is a complex process involving a number of distinct contributing micro-mechanisms, not all of which need to be present.
Quench cracking, or crack growth following a quenching process, is another example of intergranular fracture and almost always occurs by intergranular processes. [6] This process of quench cracking is promoted by weakened grain boundaries and large grain sizes and additionally influenced by the temperature gradient at which quenching occurs and ...
mild steel cracks in the presence of alkali (e.g. boiler cracking and caustic stress corrosion cracking) and nitrates; copper alloys crack in ammoniacal solutions ( season cracking ); high-tensile steels have been known to crack in an unexpectedly brittle manner in a whole variety of aqueous environments, especially when chlorides are present.
Frame of the Crystal Palace. Beams and girders were made of wrought iron with I-beam cross-section. The material was rarely used for the columns, as the cast was both stronger under compression and cheaper, so a typical iron frame building in the second half of the 19th century had cast iron columns and wrought iron beams.
The brittle fracture theory of Stoloff and Johnson, [14] Westwood and Kamdar [15] proposed that the adsorption of the liquid metal atoms at the crack tip weakens inter-atomic bonds and propagates the crack. Gordon [16] postulated a model based on diffusion-penetration of liquid metal atoms to nucleate cracks which, under stress, grow to cause ...
