Review Of Recent Developments In The Technology Of Molybdenum And Molybdenum Base Alloys

This is a brief review of new developments in the technology of molybdenum and its alloys, covering information that has become available to the Defense Information Center during the period from December 9, 1963, to March 9, 1964. (Author).

This memorandum briefly reviews a number of current developments of general interest in the technology of tungsten. Most of this information was received during the period Aug through Oct 1961. Included in the discussion are: procedures for making W sheet; extrusion; annealing of W foils; fiber metallurgy; fabrication of W and W alloy single crystals; W alloys; and oxidation of W.

Research activity on Ti-13V-11Cr-3Al, Ti-8Al1Mo-1V, and Ti-8Al-10V alloys for both high and low temperature applications is reviewed. Mechanical properties, heat treatments and processing techniques are briefly discussed. Sources of information on new developments are indicated.

A brief review is presented of techniques for special testing of materials, test results and sources of information on special testing procedures. Test data on tensile properties are presented for sheet Al and Ti alloys and for AISI 31O stainless steel to -423F. A paper on the compression testing of sheet at elevated temperatures with compression testing jigs and associated techniques is discussed briefly as well as a report on burst tests on deep-drawn pressure vessels.
