chromium–vanadium steel – this steel has less tendency to set than the plain-carbon steels; (b) silicon–manganese steel – a cheaper and rather more easily available material than chrome–vanadium steel, though the physical properties of both steels are almost equivalent. ...
On a cross-section of the aluminum alloy extruded material, a grain diameter of an intermetallic compound is 20μm or less in equivalent circle diameter; density of an intermetallic compound, whose grain diameter is 0.3 to 20μm in equivalent circle diameter, is 5×103 piece/mm2 or more; ...
The atomic radius of a chemical element is usually the mean or typical distance from the nucleus to the boundary of the surrounding cloud of electrons. Since the boundary is not well-defined, there are various non-equivalent definitions of atomic radii. Four widely used definitions are the Van ...
The lack of definite trends for ΔH values in Table 2 suggests that there is variability in work hardening of the NiTi microstructural phases along the instrument shafts and also with nominally equivalent instruments for the same ProFile product. Recent Vickers hardness measurements of clinically used...

In order to compare the effect of Si addtion on the γ phase metastability as against the equivalent addition of the Ni or Al in the HEA matrix, To values and equilibrium γ fractions were obtained for Fe42Mn28Co10Cr15Y5 (where Y5 stands for 5 at.% of elements like Si or Al or...

(2009). These submerged particles are equivalent to our grains of salt in air and are consequently truly brittle. 6.3.8 Thermal Analysis of Al Alloys The cooling curve of a solidifying alloy can be informative, usually in several ways. This is a potentially large subject, and although useful...
In the equivalent circuits, Rs denotes the sum of the solution resistance and Mg alloy surface resistance, Rf and Qf are the resistance and capacitance of the inner film, respectively; Rg and Qg are the bilayer resistance and capacitance of the intermediate coating, respectively; Rh denotes the...
