Plastic Deformation

Design Issues

· Plastic deformation is an essential step in the fabrication of most devices. This step alters the microstructure of the processed material and hence its mechanical properties.
· Energy must be expended to carry out the deformation, and minimizing this will be important in the design of the process.
· Component failure during fabrication is undesirable. Grain structure control and deformation modes that avoid local necking must be used.
· Post-deformation heat treatment, or deformation at elevated temperatures may be necessary to obtain the desired component properties.
