It is generally accepted that the different SLM processing parameters lead to a certain extent different in relative density, microstructure, and comprehensive performance of the fabricated parts. Various parameters (such as scanning velocity, laser power, etc.) are adjusted to obtain suitable laser en...
Mg(OH)2 Moles Present in a Sample: The number of particles present in a sample can be converted into the moles of the particles present in the sample by using the following relationship: n=NNA Where: Nis the number of moles of the particles present in the sample. ...
In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. ...
Electronic structure, electron transport properties, and relative stability of icosahedral quasicrystals and their 1/1 and 2/1 approximants in the Al-Mg-Zn alloy system Phys. Rev. B, 52 (1995), pp. 9300-9309, 10.1103/PhysRevB.52.9300 View at publisherView in ScopusGoogle Scholar [54] J. ...
The carbonate of metal M has the formula M_2CO_3. A sample of M_2CO_3, of mass 0.394g, required the addition of 21.7 cm^3 of a 0.263 mol\space dm^{-3} solution of hydrochloric acid for complete reaction. Calculate t...
Therefore, the relative Si-O bond length must necessarily increase with increasing coordination as the bonding polyhedra's size expands to fill the space, a general phenomenon that is well-represented by a recently proposed coordinated hard sphere highly mixture model18. The same situation is also ...
Fig. 2: The relative strengthening effect of ternary element additions to β Mg-Li Alloys. The effect of ternary elements on the tensile yield strength for as extruded alloys with an Mg/Li mass ratio of 8.1. The minimum and maximum alloy element concentrations are given. Reproduced from Jackso...
It is also shown in Figs. 6e, f, how the relative frequency of the misorientation between α- and eutectic Al increases with the higher level of Gd addition. Impurity-induced twinning theory [10] suggests an ideal ratio of atomic radii between impurity modifier element and silicon (ri:rSi...
The increased Zn addition would promote the formation of atomic clusters with high Zn content, which could play the role of “region protective shield”, because of the relative high potential of Zn. This may be the main reason that results in the corrosion rate changing tendency of Mg-Zn-...
aforementioned mixed oxides from the corresponding simple oxides were calculated and presented in Table6. The calculations prove that all the complex oxides except mullite are thermodynamically stable relative to the simple oxides at 298 K and 1 bar. Therefore, mullite was excluded from further ...
