The Electroslag Melting Process

Description: "This Bulletin traces the development of the electroslag melting process from its modest beginnings to the present. Important basic mechanisms such as electrochemistry, thermochemistry, and heat transport are described. Since the choice of flux is a unique parameter in the electroslag process, two chapters are developed to this subject. Electroslag melting experience for reactive metals, base metals, ferrous alloys, superalloys, and the refractory metals, both inside and outside the Bureau of M… more

Computer Simulation of Particulate Systems

Description: From Introduction: "The first objective of he present Bureau research was the development of a means to model random assemblies of circles and spheres that would accurately simulate actual particulate systems. The second objective of this research was to develop the computer simulations to the point where they could be used to predict real packaging or covering properties and to develop a body of data that could be used to improve and add to what is currently known about the statistical geometr… more
