English

Subject field(s)
  • Copper and Copper Alloys (Metallurgy)

  • Cuivre et alliages du cuivre (Métallurgie)
DEF

Dans le cuivre contenant de l'oxygène, état de basse ductilité provenant de l'absorption d'hydrogène à haute température, réduction interne de l'oxyde de cuivre et formation de trous ou criques intergranulaires, par suite de la formation de vapeur d'eau.
