There are two important features of bainite kinetics which can be shown by a variety of techniques, e.g. dilatometry, electrical resistivity, magnetic measurements and by metallography .
The austenite-pearlite reaction Pearlite is probably the most familiar micro structural feature in the whole science of metallography .
With the advent of metallography , and as the body of knowledge pertinent to cast iron increased, other classifications based on microstructural features became possible.
Extremely careful metallography on tapered sections through the surface of the specimen has shown that fatigue cracks initiate at intrusions and extrusions.
It is built up of a number of crystals of the same composition, given the name ferrite in metallography .
In addition, through systematic studies of metallographic structure, the researcher can determine general manufacturing techniques to establish a baseline and thus identify variations.
In well-characterized alloy systems, the metallographer can examine the microstructure and compare it to published images to identify phases and constituents.
Historically, metallographers have attached grinding papers or polishing cloths to platens in several ways.
metallographical analysis of ancient roman silver coins can shed light on the ancient minting process throughout time.
This allows the metallographer to analyze the data while it is being displayed in real time on the cathode ray tube.
