14、 existed between the two societies,Committee E-4 on Metallography of the American Society for Testing and Materials was pleased to join with the American Society for Metals in the sponsorship of a one-day symposium on Applications of Modern Metallographic Techniques at the ASM Annual Materials Engi-
15、neering Congress and Exposition on 13 Oct.1969.Committee E-4 believed that this symposium afforded an ideal opportunity to introduce an overall view of its ASTM activities to the broad materials-oriented audience at the ASM annual meeting and,at the same time to present a useful collection of papers
16、 that show how modern metallography is being applied to both routine and special materials problems.The hopes of the Committee were fully realized,as the symposium was among the two or three best-attended sessions at the Materials Congress.The terms modern and applications were the guiding criteria used by the Committee in selecting authors for the symposium and suggesting the topics for their presentations.In addition,the topics were to represent,as broadly as possible,the extensive activity of
