The Nbs Alloy Data Center

Excerpt from The Nbs Alloy Data Center: Function, Bibliographic System, Related Data Centers, and Reference Books Both an experimental point of view and the present theory of metals and alloys have pointed to the inclusion in our program of the materials and properties described below. Materials. Metals, semimetals, intermetallic compounds, and alloys consisting of two, three, and sometimes more components are of interest. In the last few years there has been an increased interest in the physical behavior of ternary and quaternary systems. All the materials to be included are the well-defined and well-characterized metals and alloys. Specifically we exclude materials which have ill-defined constitutions or heat treatments. And from which we cannot derive information on the physical properties which describe the material. Though in our scope semiconductors are not included, often some work on these materials may shed some light on other materials within our scope so that some of the more important papers are also included. Some materials are semiconducting in one phase and metallic (including superconducting) in other phases. We are generally concerned only with the metallic phases. High pressure phases are similarly included. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at www.forgottenbooks.com This book is a reproduction of an important historical work. Forgotten Books uses state-of-the-art technology to digitally reconstruct the work, preserving the original format whilst repairing imperfections present in the aged copy. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in our edition. We do, however, repair the vast majority of imperfections successfully; any imperfections that remain are intentionally left to preserve the state of such historical works.

This Index contains literature references to -- 10,000 research papers on physical properties of metals and alloys. The Index contains all NMR Knight shift papers and soft x-ray emission papers. It also contains many soft x-ray absorption papers and a number of papers on generally related topics such as susceptibilities, specific heats, hyperfine fields, and band structures. The papers are annotated in depth and the coded information put onto a magnetic tape. The Permuted Materials Index was created from this tape, listing alloys under each of their constituent components (i.e., CuNi appears under CuNi and under NiCu alloys).

The Alloy Data Center, part of the National Standard Reference Data System, has two primary functions. One is to stimulate cooperation and coordination among the existing data centers in the area of the physical properties of well characterized alloys. The final data generated by these centers for publication should be consistent with one another where correlation or possible overlap exists. The other purpose is the collection (from publications as well as private communications), evaluation, and publication of data in some areas where special competence exists in the Alloy Physics Section. Of interest to the center are metals, semimetals, intermetallic compounds, and alloys. Excluded are those materials which have ill-defined constitutions and heat treatments. An automated system was developed to meet the bibliographic needs of the center. This system will be described as well as the specific properties of interest. The system presently contains a complete annotated file dealing with NMR Knight shift measurements. The soft X-ray spectroscopy compilation is being kept up-to-date with the same system. (Author).
