Effects of curing temperature and age on the mechanical properties and damage law of coal-based solid waste cemented backfill by Xiang He, Longqiang Wei, Ke Yang, Zhiqiang Wen, Lianfu Zhang, Yongqiang Hou

“…Since the curing temperature and age play an essential role in affecting the strength of the backfill, the uniaxial compression test, acoustic emission damage monitoring, and microscopic scanning electron microscopy were carried out on the standard cube specimens with the curing temperature of 20, 27, 35, 42.5 and 50 °C (accompanied by the curing age of 3, 7, 14 and 28 days, respectively). The microstructure evolution and damage constitutive model of coal-based waste cemented backfill (CWCB) were discussed to reveal how CWCB strength develops. …”

Spatial mapping of the localized corrosion behavior of a magnesium alloy AZ31B tungsten inert gas weld by Leslie G. (Bland) Miller, Corey M. Efaw, Rebecca F. Schaller, Kari Higginbotham, Steve D. Johns, Paul H. Davis, Elton Graugnard, John R. Scully, Michael F. Hurley

“…Sections of a magnesium alloy, AZ31B, joined with tungsten inert gas (TIG) welding, were examined with scanning electrochemical microscopy (SECM) and scanning Kelvin probe force microscopy (SKPFM) to investigate corrosion mechanisms by correlating observed corrosion behavior with weld-affected microstructural variations. Insight into the changing nature of the galvanic couples between weld zones and at localized microgalvanic sites were investigated using SECM and SKPFM to map both electrochemically active regions and Volta potential differences across the weld-affected zones. …”
