The phrase "a primary phase" is correct and usable in written English.
It can be used to refer to an initial or main stage in a process or development.
Example: "In the project timeline, we will focus on completing a primary phase before moving on to the subsequent stages."
Alternatives: "a main stage" or "an initial phase".
To overcome this challenge, several advanced composite fuels have been proposed with uranium nitride as a primary phase.
Above 7.2% Mg, it solidifies as a primary phase and also during the binary and ternary reactions.
Different forms of Mo-oxide, including MoO2, Mo4O11, Mo8O23 and MoO3 have been observed along with Mo as a primary phase.
However, when the melt undercooled below Tp was dropped onto the copper chill plate with high thermal conductivity, YIG solidified around the chill plate as a primary phase.
We find that for ∆T < 707 K, the α-(Fe,Si) phase has a higher nucleation rate compared to that of the 1 13 phase, and it is a primary phase in a slow solidification process.
As the undercooled temperature change, ∆T, is less than 707 K, the α-(Fe,Si) phase has a higher nucleation rate compared to that of the 1 13 phase on the free surface of the ribbon, and it is therefore a primary phase in a slow solidification process.
In approximately 90% of cases, the disease manifests with an initial primary phase characterized by a relapsing-remitting presentation (RRMS) where the patient experiences alternating episodes of neurological impairment, followed by recovery [ 2].
The effect of a concomitant secondary phase transformation on the coarsening of spherical precipitates inherited from a previous primary phase transformation is investigated.
The microstructure of samples at low undercoolings consists of a residual primary phase α2, peritectic phase ε and inter-dendritic ε β eutectic.
The nucleation rate of the 1 13 phase is faster than that of the α-(Fe,Si) phase on the cooled surface of the ribbon, thus resulting in the 1 13 phase as a primary solidification phase.
A more globular primary phase was achieved at low values of fs, but this was not the optimum morphology for mechanical properties.
