    Abstract: PURPOSE: Method of making high strength-high stiffness beta titanium alloy is provided to produce TiB(titanium boride) precipitates by a suitable method such as a pre-alloyed powder metallurgy technique, thereby improving mechanical properties of beta titanium alloys, Ti-5553. CONSTITUTION: A method of making high strength-high stiffness beta titanium alloy comprises introducing boron into a beta titanium alloy to produce TiB precipitates; heat treating the titanium alloy with TiB precipitates by homogenization above the beta transus temperature of the alloy; subjecting the heat treated alloy to a hot metalworking operation below the beta transus temperature; heat treating the worked alloy with a solution treatment below the beta transus temperature; and ageing the solution treated alloy below the beta transus temperature. The TiB precipitates are accomplished by a casting, cast-and-wrought processing, powder metallurgy techniques such as gas atomization and blended elemental approach. The titanium alloy powder is consolidated by hot isostatic pressing.

    Abstract: PURPOSE: A negative electrode active material is provided to have high capacity with regard to the theoretical capacity of Si, thereby improving initial discharging capacity. CONSTITUTION: A negative electrode active material comprises a Si-Sn-Fe-Cu based alloy, and a Si phase has an area ratio of 35-80% based on total negative electrode active materials. The Si phase is dispersed in a matrix phase. The matrix phase contains a Si-Fe compound phase which is crystallized by the Si-phase; and Sn-Cu compound which surrounds the Si phase and the Si-Fe compound. The Si-Fe compound is crystallized with an area ratio of 35-90% in the total matrix phase. The matrix phase additionally contains Sn phase which is inevitably crystallized with a surface area of 15% or less.
