White Spot
Explanation:
Der Begriff wird anscheinend im Singular verwendet. Ich habe ein bisschen gesurft, es kann einige verschiedene Ursachen dafür haben.
"White spot is the term for a particulate dispersion lean in niobium found in vacuum arc remelted (VAR) ingots of niobium containing nickel-based superalloys, such as INCONEL718, that can be detrimental to the mechanical properties. White spot can result from exogenous fragments that fall into the VAR melt pool and remain incompletely melted."

Die Quelle die ich oben gefunden habe bezieht sich auf Superlegierungen, die sind ja relativ neu, in meinen Wörterbüchern habe ich auch nichts gefunden (Canada etch auch nicht).

agree  Doreen Schäfer: Habe über Google auch fast nur die englische Bezeichnung (auch Mehrzahl) in dt. Fachtexten gefunden oder schlicht Oktay's & Conny's "weiße Flecken"
