METALLURGICAL TESTING
Metallography or material testing for microstructure analysis is very important analysing the material micro structure and also to understand the decarburisation and carburisation of the screw, whether the material has been properly heat treated and adheres to the parameters of the standard can be better understood by the proper analysis of metal by way of microstructure analysis and with the help of various hardness testers.
Metallography is the study of the microstructure of all types of metallic alloys. It can be more precisely defined as the scientific discipline of observing and determining the chemical and atomic structure and spatial distribution of the grains, constituents, inclusions or phases in metallic alloys.
