Metals Of The Future

Chemical Industry Provides the Base from Which Spring the Marvels of Metallurgy. Important to Tomorrow's Applications of Metals Is the Developing Knowledge of the Rarer Elements and Their Value in Extending the Usefulness of the More Common Metals in Use Today

By D. H. Killeffer


A Powerful New Tool And Technique, The Microradiographic Application of X-Rays in Metallurgy, Not To Be Confused with the Familiar Radiography to Which It Is An Auxiliary, Is Giving Aid in the Improvement of Existing Alloys and the Development of Many New Ones

By Albert G. Ingalls and S. E. Maddigan

Plastics Plus Metals

Additional Uses for Both Materials are Supplied by Skilful Application of Techniques Now Developing. Metal Coatings for Plastics Take Advantage of Characteristics Not Found in Either Material Alone. Metal Inserts and Assembly Devices Offer Diversity to the Designer

By Charles A. Breskin

Partners In Production

A Series of Pincers Attacks by Mechanical Engineers and Metallurgists Has Resulted in High-Speed Copper Machining, Better Band Saws, Tougher Cams, Improved Metallizing Methods, and a Number of Other Industrially Important Developments--And the End Is Not Yet in Sight

By Edwin Laird Cady

Drawing It Out Fine

Wire Drawing Today Is a Complex Series of Precise Operations Which Depend Upon Accurate Dies and the Careful Regulation of Lubricants and Drawing Speeds. The Drawing of Fine Wires Necessary in Many Electronic Devices is Expected in Itself to Grow into a Major Industry
