All children were given a patch of eutectic mixture of local anesthetic, because midazolam does not have analgesic properties, and later were given the nasal spray.
The large volume fraction of primary and/or eutectic carbides in their microstructures provides the high hardness needed for crushing and grinding other materials.
Modification of the hypoeutectic alloys is particularly advantageous in sand castings, and can be effectively achieved through the addition of a controlled amount of sodium or strontium, which refines the silicon eutectic .
When the metastable path is followed, the rich carbon phase in the eutectic is the iron carbide; when the stable solidification path is followed, the rich carbon phase is graphite.
Therefore, in exceptional cases, alloys with less than 2% C can solidify with a eutectic structure and therefore still belong to the family of cast iron.
