Chemical Diffusivities and Their Hidden Concentration Units
Abstract Ternary and higher order multicomponent alloys have chemical diffusivities that are functions of the concentration units used in the diffusion equation. However this dependence is not obvious, since all multicomponent diffusivities have the same units of $ m^{2} $/s. In a sense the concentr...

| 520 | |a Abstract Ternary and higher order multicomponent alloys have chemical diffusivities that are functions of the concentration units used in the diffusion equation. However this dependence is not obvious, since all multicomponent diffusivities have the same units of $ m^{2} $/s. In a sense the concentration units are hidden. It is proposed herein that the concentration units be added to the name of experimental and predicted diffusivities, for example “mole fraction diffusivity” or “mass fraction diffusivity” to alert users to the concentration units that should be used when solving the diffusion equation. Linear equations that transform the mole fraction chemical diffusivity into five other chemical diffusivities are given. In addition, it is shown that differences between molar diffusivities and those between density diffusivities go to zero as the solute concentration goes to zero and it is shown that density diffusivities which assume constant molar volume are in fact mole fraction diffusivities and have no density properties when used in the diffusion equation. An example is given of five chemical diffusivities for a Ni-4at.%Cr-6at.%Al-4at.% Mo alloy at 1100 °C that were calculated from the measured, quaternary, mole fraction chemical diffusivity. | ||

However this dependence is not obvious, since all multicomponent diffusivities have the same units of $ m^{2} $/s. In a sense the concentration units are hidden. It is proposed herein that the concentration units be added to the name of experimental and predicted diffusivities, for example “mole fraction diffusivity” or “mass fraction diffusivity” to alert users to the concentration units that should be used when solving the diffusion equation. Linear equations that transform the mole fraction chemical diffusivity into five other chemical diffusivities are given. In addition, it is shown that differences between molar diffusivities and those between density diffusivities go to zero as the solute concentration goes to zero and it is shown that density diffusivities which assume constant molar volume are in fact mole fraction diffusivities and have no density properties when used in the diffusion equation. An example is given of five chemical diffusivities for a Ni-4at.%Cr-6at.%Al-4at.% Mo alloy at 1100 °C that were calculated from the measured, quaternary, mole fraction chemical diffusivity.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">chemical diffusivity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">diffusion modeling</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">diffusivity measurements</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">interdiffusion</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">material properties</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">multicomponent diffusion</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">mutual diffusivity</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of phase equilibria and diffusion</subfield><subfield code="d">Boston, Mass. : Springer, 2004</subfield><subfield code="g">35(2014), 5 vom: 07.

Chemical Diffusivities and Their Hidden Concentration Units |
| abstract |
Abstract Ternary and higher order multicomponent alloys have chemical diffusivities that are functions of the concentration units used in the diffusion equation. However this dependence is not obvious, since all multicomponent diffusivities have the same units of $ m^{2} $/s. In a sense the concentration units are hidden. It is proposed herein that the concentration units be added to the name of experimental and predicted diffusivities, for example “mole fraction diffusivity” or “mass fraction diffusivity” to alert users to the concentration units that should be used when solving the diffusion equation. Linear equations that transform the mole fraction chemical diffusivity into five other chemical diffusivities are given. In addition, it is shown that differences between molar diffusivities and those between density diffusivities go to zero as the solute concentration goes to zero and it is shown that density diffusivities which assume constant molar volume are in fact mole fraction diffusivities and have no density properties when used in the diffusion equation. An example is given of five chemical diffusivities for a Ni-4at.%Cr-6at.%Al-4at.% Mo alloy at 1100 °C that were calculated from the measured, quaternary, mole fraction chemical diffusivity. © ASM International 2014 |
