It has been discovered that electroslag remelting of titanium metal or alloys under controlled partial pressures of nitrogen, and somewhat oxygen, can dissolve nitrogen-rich inclusions to help eliminate or reduce initiation sites for cracks. The process for the electroslag remelting of titanium and titanium alloys ensures that nitrogen-rich inclusions are dissolved or at least minimized during the melting process.
Il s'est avéré qu'une seconde fusion sous laitier de titane ou d'alliages de titane sous des pressions partielles contrôlées d'azote, et de quelque peu d'oxygène, pouvait dissoudre des inclusions riches en azote et ce, afin de contribuer à éliminer des sites promoteurs de déchirures ou à les réduire. Ce procédé de seconde fusion de titane et d'alliages de titane garantit la dissolution d'inclusions riches en azote ou au moins leur réduction à un niveau minimal durant le processus de fusion.
