... coating system has a higher impact wear resistance. The coatings with multilayer structure (TiAlN) demonstrate better cracking resistance. Resistance to cracking as well as to impact wear depends on coating E/H ratio (at lower loads) as well as on substrate material E/H ratio (at higher loads...

...Mohammad Pour-Ghaz; Jason Weiss Recent research has demonstrated that cracking can be monitored in concrete using conductive surface elements. One complication with using conductive surface elements is that each element requires a separate data acquisition channel. To overcome this hurdle...

...Nailu Chen; Xunwei Zuo; Shu Zhou; Jun Xu Some steels fail to meet mechanical property requirements after oil quenching with subsequent tempering. If water is used in an attempt to facilitate better property formation, quenching cracks may then be encountered. To address these situations...

...Aleksandra Radlinska; Brooks Bucher; Jason Weiss The restrained ring test has recently been standardized (ASTM C1581-04) as a test method to assess the restrained shrinkage cracking susceptibility of a concrete mixture. Unfortunately, there is currently a lack of published information regarding...

...J-H Moon; F Rajabipour; B Pease; J Weiss Over the last decade, the restrained ring test has trequently been used to assess the cracking susceptibility of a concrete mixture when it is restrained from shrinking treely. Despite the trequent use of the ring test, limited analysis has been performed...

... as a control (reference) image. Four distinct surface defects are quantifiable in the samples. These are cracking (crazing), visual color change, spatial uniformity of deterioration (due to dirt pick-up and uneven color change, or both), and overall surface texture. Chalking and dirt pick up, as rated visually...

... and anodic applied potentials. The results of stress corrosion cracking testing without applied potentials indicate that the ductility of both alloys was enhanced in terms of percent elongation, percent reduction in area, failure strain, and the time-to-failure with increasing temperature indicating improved...
