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.
