Title: Corrosion-resistant zirconium-based alloy
Inventor: EITO YOSHINORI
IPC: C22C32/00
Filed: 1988-03-31
Abstract: PURPOSE:To effectively prevent the nodular corrosion in the title alloy by uniformly dispersing an Fe-contg. intermetallic compound to the whole structure of a Zr-based alloy. CONSTITUTION:An intermetallic compound contg. Fe and having 0.17-0.01mm grain size is uniformly dispersed into a Zr-based alloy for a light water reactor. As the intermetallic compound, the one contg. Zr and Fe, the one contg. Zr, Fe and Cr, the Zr (Cr,Fe)2 type-one, etc., are used. At the time of using the Zr-based alloy in a nuclear reactor, as the initial stage, Fe forms solid solution into the matrix of the Zr-based alloy and a precise acidic film having excellent corrosion resistance and uniform thickness is generated to suppress nodular corrosion and to suppress the generation and growth of a porous oxidizing film. Since the corrosion resistance of the alloy is improved as radiation proceeds, it is effective for a fuel having high burning degree which is burnable for a long period of time.

Title: Production of super-hard aluminum composite material
Inventor: CHO TAKAO
IPC: C22C1/10
Filed: 1993-02-24
Abstract: PURPOSE:To simplify the production of aluminum composite material and to produce super-hard aluminum composite material which is obtained by in situ forming and dispersing fine nitride and boride particles in aluminum. CONSTITUTION:Aluminum or an aluminum alloy is melted on a powdery mixture consisting of powdery boron nitride and powdery metal such as Hf, Zr, Tl or Ta under an argon or nitrogen atmosphere to impregnate the molten metal into the powdery mixture.
