Alloying and impurity effects in vanadium-base alloys

Journal of Nuclear Materials, 1986
Abstract Vanadium-base alloys offer a number of significant advantages over other alloy systems for fusion reactor structural applications. However, the properties and performance of vanadium are strongly influenced by the choice of alloying additions and the presence of impurity elements, and these effects are reviewed in this paper.

Investigation on mechanical alloying process for vanadium alloys

Journal of Nuclear Materials, 2013
Abstract Mechanical alloying (MA) is an efficient approach for fabricating particle-dispersion alloys, and has recently been introduced to strengthen structural materials including vanadium alloys for fusion application. Dissolution behavior of the alloying elements is a key issue for optimizing MA in fabricating particle-dispersion vanadium alloys ...

Recovery and recrystallization of vanadium alloys

Journal of Nuclear Materials, 1996
Abstract A vanadium alloy containing 4 wt% Cr and 4 wt% Ti has been identified as a promising candidate structural alloy for liquid metal-cooled blankets in fusion power reactors. Studies of recovery, recrystallization and precipitation kinetics are in progress to provide the metallurgical basis for the development of improved properties.

Interdiffusion in niobium-vanadium alloys

Journal of the Less Common Metals, 1965
Abstract A determination of the variation of interdiffusion coefficient with composition for Nb-V alloys has been made for diffusion temperatures of 1404°, 1505°, 1630° and 1750°C. Three types of doubly infinite couples were employed: Nb/V, Nb/alloy and V/alloy, where the alloy was 50 at.% Nb.

Columbium-vanadium alloy system

JOM, 1954
On the basis of microscopic studies, melting-point observations, and X-ray analyses, a phase diagram is proposed for the Cb-V system. A complete series of solid solutions is formed with a minimum in the solidus at 1810°C near 35 wt pct Cb. No compounds or intermediate phases were found in the system above 650°C.

Microstructure of Vanadium-Oxygen Alloys

Proceedings, annual meeting, Electron Microscopy Society of America, 1981
The present study is a continuation of our investigation on in situ oxidation of vanadium and vanadium-titanium alloys. Vanadium is a reactive metal and forms a large number of oxides during high-temperature exposure to oxygen. The microstructure of the oxides formed during the first stages of oxidation and the transformations between oxide phases are ...

EXPLORATION OF VANADIUM-BASE ALLOYS

1955
Abstract : This is the third annual report. The oxidation study on vanadium alloys has been further pursued and the conclusion has been reached that satisfactory oxidation resistance at elevated temperature of vanadium-base alloys cannot be rendered by alloying alone but possibly by electroplating. Major efforts have been directed toward evaluating the

IMPROVED VANADIUM-BASE ALLOYS

1961
Abstract : Alloys based on V-5w/oTi-20w/oCb and V-60w/oCb were found to exhibit excellent fabricability and weldability with good retention of strength to at least 2200 deg F. Ultimate tensile strength values of materials at the 60w/o columbuim level measured under He were above 60,000 psi at 2000 deg F and up to 44,400 psi at 2200 deg F; the strongest
