Auger analysis was performed using a high resolution scanning auger electron microscope and auger electron spectroscopy. Elemental auger contour maps for corroded sulphide inclusions in stainless steel were presented. It was found that the copper enriched-manganese sulphide inclusions were uniformly corroded, which might be due to CU2S deposition on the surface of corroding inclusions. In contr...
Austenitic high manganese steels exhibit outstanding mechanical properties, such as energy absorption, owing to various deformation-mechanisms dislocation slip, twinning-induced plasticity (TWIP) and transformation-induced (TRIP). Here, we show a novel thermomechanical treatment manufacture steel Fe–18Mn-0.3C (wt.-%) with excellent performance by combining these three deformation-mechanisms. Th...
OBJECTIVE To determine the blood lead levels and trace elements (copper and manganese) in traffic police constables in Islamabad in order to assess the effects of environmental pollution on the levels of metals in body fluids. METHODS Blood samples were collected from 47 male traffic police constables, 21 to 45 years of age, posted in different areas of Islamabad and controlling traffic from ...
BACKGROUND Given mounting evidence for adverse effects from excess manganese exposure, it is critical to understand host factors, such as genetics, that affect manganese metabolism. METHODS Archived blood samples, collected from 332 Mexican women at delivery, were analyzed for manganese. We evaluated associations of manganese with functional variants in three candidate iron metabolism genes: ...
We measured the manganese content of mononuclear blood cells and the manganese concentrations in whole blood and plasma from 31 healthy volunteers and 25 patients receiving total parenteral nutrition (TPN) (i.e., no dietary manganese). The manganese content (mean +/- 2 SD) of mononuclear blood cells and the manganese concentration in whole blood and plasma in the healthy volunteers were 8.84 +/...
