... Accelerated corrosion of metallic implants in vivo can generate both soluble and insoluble products that can be detected locally and systemically. Retrieved stainless steel implants for trauma fixation or spinal instrumentation demonstrate iron and chromium-containing solid products...

... for both long fatigue life and noise performance and high corrosion resistance. Carbide size and hardness comparable to AISI 52100 steel were essential for the new stainless bearing steel(ES1), so we lowered the carbon and chromium contents and increased the nitrogen content of AISI440C. To control...

... A major on-going research project is described that aims at generating relevant data for future risk assessments of environmental effects caused by copper, zinc, chromium and nickel release from roof materials. Cross-disciplinary activities have been implemented that range from the metal release...

.... Column and batch leaching tests are conducted on the cement stabilized sludge containing heavy metals (lead and chromium). The batch test is in accordance with the Japanese regulatory requirement. The column leaching test is performed to account for hydraulic conductivity. The accumulated mass of heavy...

... The distribution of chromium (Cr) in fractionated serum was studied from peripheral blood of patients with and without Cr-containing Cobalt-base alloy total joint replacements: 1)10 patients with cobalt-chromium-base alloy prostheses; and 2) 10 age-matched controls without implants. Two...

... The effectiveness of a quicklime-based treatment on reducing the mobility of heavy metals (lead, chromium, arsenic and mercury) in contaminated soils was evaluated using both slurry batch-contact and optimum water content compaction experimental techniques. The results indicated that lead...

... and the relation of the leaching results to applicable regulations are discussed. Site A was a large manufacturing facility covering about 300 000 m 2 (80 acres). Soil contamination included lead, chromium, and arsenic. The soil to be stabilized contained total concentrations of up to 19 000 mg/kg lead, 1600 mg...

... Tensile properties at 298 and 77 K of the electron-beam-welded joints of low neutron activation vanadium-binary alloys were evaluated. (1) Yield and tensile strengths of the welded specimens increased with an increase of carbon of up to 1.6%, boron of up to 5.0% and chromium of up to 9.3...

... Three chromium-containing steels, 3CR12, Alloy 825, and AISI 431, have been subjected to cyclic loading in air, distilled water, and low chloride containing waters. The 3CR12 steel showed significant fatigue crack growth rate (FCGR) enhancement when subjected to the aqueous environments...

... test with its own methodology and the cyclic plunge test were used. Three levels of total residual contents were obtained through addition of copper, chromium, and nickel in ingots. The amounts of these three elements were changed simultaneously to simulate practical conditions. The total residual...

... Oxidation kinetics at 300°C in dry oxygen of 0.5 wt% binary alloys of iron, nickel, and chromium in zirconium were determined for several surface preparations. Further, chemical profiles of the oxides as they existed on the matrix and on the precipitates were obtained by sputtering and Auger...

It was validated using a nontoxic industrial effluent spiked with hexavalent chromium and naphthenic acids. wastewater effluent toxicity Daphnia pulex...

... samples, the less than 20-µm fraction was the largest fraction, accounting for almost 50% of the total. Particles recovered in the coarsest (>125 µm) fraction were readily distinguished as plant remains and cellulose fibers. The distribution of eight metals, chromium, iron, manganese, nickel, copper...

... The toxic effect of hexavalent chromium on the growth rate of ten species of estuarine phytoplankton was examined in a defined growth medium. The concentration causing 50% inhibition of growth rate varied by a factor of more than 50 among the species. Three possible causes of interspecific...
