TANTALUM-SILICON ALLOYS AND PRODUCTS CONTAINING THE SAME AND PROCESSES OF MAKING THE SAME |
摘要 |
An alloy comprising tantalum and silicon is described. The tantalum is the predominant metal present. The alloy also has a uniformity of tensile strength when formed into a wire, such that the maximum population standard deviation of tensile strength for the wire is about 3 KSI for an unannealed wire at finish diameter and about 2 KSI for an annealed wire at finish diameter. Also described is a process of making a Ta-Si alloy which includes reducing a silicon-containing solid and a tantalum-containing solid into a liquid state and mixing the liquids to form a liquid blend and forming a solid alloy from the liquid blend. Another process of making a Ta-Si alloy is described which involves blending powders containing tantalum or an oxide thereof with powders containing silicon or a silicon-containing compound to form a blend and then reducing the blend to a liquid state and forming a solid alloy from the liquid state. Also, a method of increasing the uniformity of tensile strength in tantalum metal, a method of reducing embrittlement of tantalum metal, and a method of imparting a controlled mechanical tensile strength in tantalum metal are described which involve adding silicon to tantalum metal so as to form a Ta-Si alloy.
