    摘要： This invention relates to a high temperature melting composition and method of using the composition for brazing high temperature niobium-based substrates, such as niobium-based refractory metal-intermetallic compositions (RMIC), including but not restricted to niobium-silicide composite alloys. The high temperature melting composition can include one or more alloys. The alloys include a base element selected from titanium, tantalum, niobium, hafnium, silicon, and germanium. The alloys also include at least one secondary element that is different from the base element. The secondary element can be selected from chromium, aluminum, niobium, boron, silicon, germanium and mixtures thereof. When two or more alloys are included in the composition, it is preferable, but not required, to select at least one lower melting alloy and at least one higher melting alloy.; The composition is preferably a homogemeous mixture of the two or more alloys combined in powder form.

    摘要： A method of fabricating a Ti-6Al-4V titanium alloy component including solution heat treating a forged Ti-6Al-4V titanium alloy component at a temperature within the alpha + beta two-phase field for the material of the component for a predetermined period of time, and subsequently cooling the component. The component is then age heat treated using an overaging process at a predetermined overaging temperature for a predetermined time, and the component is cooled to room temperature. The overaging temperature is selected to be a higher temperature than an aging heat treatment temperature for effecting a maximum yield strength in the component.

    摘要： The application relates to the problem of alloying a melt, preferably a titanium melt, with oxygen by adding formed articles such as pellets containing a master alloy such as Ti02. The articles should fully and homogeneously disperse in the melt, while the carbon content of the melt should be kept below an allowable maximum, preferably below 0.04 wt. %. The formed article may also comprise iron or palladium. To solve this problem, the formed article consists of 70-82 wt. % of a master alloy and 18-30 wt. % of a high-carbon organic polymer such as ethylene vinyl acetate or a low density polyethylene. The homogeneous dispersion is achieved eg by the formed articles having a similar size as the other raw feed materials which are added to the melt.
