Alloy Engineering, Berea, Ohio, released Science and Art of Atmo-sphere Furnace Muffles, a brochure that describes its wide range of muffle configurations. The muffles are fabricated from a variety of high-temperature and corrosion-resistant alloys. The 8-p brochure explains how the company uses CAD software with solid-modeling and finite-element analysis capabilities to study the physical and thermal responses of critical muffle features to operational conditions and optimizes each design to maximize life.
