Standard DDS 225 Principles of Metallurgy Course Description Introduces the fundamental physical properties of metals. Describe the chemical, physical, mechanical, and dimensional properties of materials. Limitations Define stress, strain, hardness, and toughness.
Metals Describe the extraction of metals from ores and methods of consolidating metals.
Plasticity Discuss plastic deformation, annealing, and hot working. Ceramics Explain why ceramic materials are strong in compression, weak in tension, and brittle. Specifications Interpret steel size, description, finish, property, and tolerance specifications. Processes Describe the heat treating processes of hardening, tempering, softening a hardened structure, recrystallization stress relief, hot working operations, and diffusion of alloying elements. Discuss the benefits of surface and local hardening.
