Section 6 - The Mechanical Properties of Materials Students will be able to: 6.1 describe a tensile test and relate measured quantities to stress, strain, modulus, ductility, and toughness. 6.2 draw stress-strain diagrams characteristic of the different classes of engineering materials 6.3 distinguish between elastic and plastic deformation 6.4 describe the role of dislocations in plastic deformation of crystalline materials 6.5 name and describe the principal methods of strengthening of a metal: strain hardening (i.e. work hardening), solution strengthening, precipitation strengthening, and grain refining. 6.6 describe different methods for measuring hardness and relate hardness to yield strength 6.7 relate changes in a cold-worked microstructure due to annealing to corresponding changes
