The phrase "adding to the melt" is correct and usable in written English.
It can be used in contexts related to cooking, chemistry, or processes involving melting substances, where something is being incorporated into a melted mixture.
Example: "As the chocolate begins to melt, start adding to the melt the chopped nuts for a delightful texture."
Alternatives: "contributing to the melt" or "mixing into the melt".
In some cases dyes or pigments may be added to the melt or solution prior to the spinning of the fibre.
However, when a small amount of magnesium is added to the melt before casting, the result is a "spheroidal graphite" iron, in which graphite appears as spherical nodules and ductility is greatly increased.
Then, Mg was added to the melt to enhance the wettability between the metal matrix and reinforcement particles.
Finally, a styrene butadiene styrene block copolymer (SBS) is added to the melt and mixed for another 5 min.
SiC and B4C particles, preheated to a temperature of 790°C along with magnesium were continuously added to the melt during stirring.
Preheated SiC was added to the melt with continuous stirring, and finally, the composite slurry was poured into the cast iron mould.
As the inoculant Al 3% Ti 1% B was added to the melt in a series of experiments relatively small equiaxed grains were observed in the as-cast macrostructure.
Hassan et al. (2009) fabricated SiC-reinforced Al-Mg-Cu composite by stir casting process, in which the aluminium ingots and copper powder were melted together at 850°C and pre-oxidized SiC powder was added to the melt.
The present contribution shows that the mechanism is the same as that evidenced recently in Al Zn alloys, when small amounts of Cr (1000 ppm) are added to the melt (Kurtuldu et al., 2013).
The equiaxed solidification of Al 20 wt.% Zn alloys revealed an unexpectedly large number of fine grains which are in a twin, or near-twin, relationship with their nearest neighbors when minute amounts of Cr (1000 ppm) are added to the melt.
