interdiffusion

At lower temperatures, about 400-450 C, an interdiffusion process takes place at the junction.

We can then define the interdiffusion coefficient D as follows:

A heat treatment then causes interdiffusion of the metals and formation of the required intermetallic compound.

The doctrine of the Kegon School of the 'unimpeded interdiffusion' of all Ji, things.

Soft solder joins like a glue, without significant interdiffusion (or exchange) with the metals it bonds, leaving the composition of metal and solder essentially unchanged.

As already set out, the Kegon philosophy of Jijimuge, of 'unimpeded interdiffusion' of Absolute Reality and each individual 'thing', is the last word in human thought.

Metallisation failures are more common and serious causes of FET transistor degradation than material processes; amorphous materials have no grain boundaries, hindering interdiffusion and corrosion.

In a similar manner, Darken's equations were used in a paper by Wantabe et al, on the nickel-aluminum system, to verify the interdiffusion coefficients that were calculated for nickel aluminum alloys.

SOME MAHAYANA PRINCIPLES unimpeded interdiffusion of all particulars.

Hard solders join by interdiffusion at high temperatures with the metals being bonded, so that composition at the join will be somewhere between that of the solder and that of the object.

The 'Pairs of Opposites' are modes of the ultimate antithesis of Being and not-Being and are infinite in number; all the parts and the whole are related in the uttermost ' interdiffusion' of Jijimuge.

When two blocks of the same polymer are brought together and held at a temperature just above the T g for a time t, interdiffusion of the chains takes place from each block across the interface (see figure 12.6) thereby joining the blocks together.

Ion mixing (IM) is essentially similar in result to interdiffusion, hence most models of ion mixing involve an effective diffusion coefficient that is used to characterize thickness of the reacted layer as a function of ion beam implantation over a period of time.

One popular mechanism suggested by geochemists is that Liesegang rings develop when there is a lack of convection (advection) and has to do with the interdiffusion of reacting species such as oxygen and ferrous iron that precipitate in separate discrete bands which become spaced apart in a geometric pattern.

Thermodynamic effects are also not considered in this basic interdiffusion equation, but can be modeled by equations that consider the enthalpies of mixing and the molar fractions of the target species, and one can thereby develop a thermodynamic effective diffusion coefficient reflecting temperature effects (which become pronounced at high temperatures).
