Metallography
Metallography
Metallography can be identify the characteristics and composition of metal structure through research and observation in association with mechanical and physical properties in the metals and alloys.
We must study the interrelationship between the properties of material and a change of metal structure in manufacturing process in order to apply metallurgical principle.
Metallurgical microscope can seeing the size, shape, arrangement of the metal particles and observed variety phase and micro-structure of the metal, also it can be study the effect of the heat treatment, the effect of processing and other on the micro-structure of the metal, also the mechanical properties you can also relationships with research.
It can know the effect of the heat treatment, Machining and etc. treatment that affect the metallurgical structure, and to study the relationship between the mechanical properties.
Macro-structure of metal is a test for observing the microstructure of the weld metal and alloys with a low magnification the defects, such as the a lower rate, failure mode, density of metallic crystal, lamination layer, quality of penetration, crack, blow hole, slag inclusion, banded structure, microfissure, etc.
Macro test is the most direct and important test to check the good or bad of the sample, since the advantage which can be observed over a large range than the microscope.
HYUN TECH provide to test solutions for evaluate the metallic microstructure of various materials.
