EVALUATION TEST METHODS FOR REFRACTORY METAL SHEET MATERIALS

摘要

This is the third revision of recommended test methods for refractory metal sheet published by the Materials Advisory Board Refractory Metals Sheet Rolling Panel. The Panel's objective was to provide a standard basis for the test eval¬uation of sheet materials produced under various Department of Defense development programs. A subpanel was appointed for this purpose. After a thorough canvas of prominent suppliers and users of refractory sheet metals, the first recommendation were published in September 1961 as MAB-176-M to define common tensile, creep-rupture, bend, and thermal properties tests. Subsequently, as the Department of Defense programs progressed, more specialized tests became necessary to evaluate fabrication characteristics and to provide preliminary design data. Again, after discussion with principal organizations engaged in direct applications, a revised edition was published April 22, 1963, as MAB-192-M. Since that time, criticisms and comments have been reviewed by the subpanel with qualified individuals repre¬senting governmental and commercial laboratories. The present edition is based upon these reviews. Changes have been made in the tests described in Sections 1 through 6. The tests in Sections 7 through 15 are unchanged from Report 192-M.nIn preparing these recommendations, the subpanel has deferred where possible to prominent ASTM standards. The subpanel thanks the many government and industrial laboratories who gave valuable advice and comment.
