Spheroidising increase machinability.

Full annealing increases machinability. But in process annealing increase only ductile property.

Process annealing is also known as stress relief annealing.

Microscopes (sometimes called metallographs) are used to examine and characterize the micro-structure looking close up at magnifications from 20 to 2000 times, and higher.

Electron microscopes use beams of energy with much smaller wavelengths than light to "see" at very high magnifications as high as 10,000,000 X. Special types of electron microscopes are able to tell us the exact composition of the microstructure components.
