Determining Ductile Fracture Toughness in Metals Xiang (Frank) Chen, Randy K. Nanstad, Mikhail A. Sokolov, and Eric T. Manneschmidt Ductile fracture toughness testing is useful for evaluating a material’s structural integrity. Three different techniques are explored in this article. TECHNICAL SPOTLIGHT Analyzing Metals with Handheld Laser-Induced Breakdown Spectroscopy (LIBS) LIBS is taking its first leap into portable metal analysis. TECHNICAL SPOTLIGHT In-House vs. Outsourced Materials Testing: How to Decide When making the choice between onsite and outsourced testing, quality and time are as important as ROI in the final analysis. ITSC 2014 SHOW PREVIEW Not Fiction: Thermal Spray the Key Technology in Modern Life The International Thermal Spray Conference and Exhibition (ITSC), taking place May 21-23 in Barcelona, Spain, features a three-day exposition, conference, poster session, education courses, and much more. I CME Helps Develop Friction Stir Welding Process for Steels Yu-Ping Yang Developing a process model to improve understanding of thermal, mechanical, and microstructural effects—plus optimizing process parameters—during the friction stir welding of steels is essential in order to implement integrated computational materials engineering. METALLURGY LANE The Age of Steel: Part II Charles R. Simcoe By 1875, the Bessemer steel industry had spread across the country from eastern Pennsylvania to St. Louis, with the epicenter in Pittsburgh.
