Etched mild steel --> you will be able to to see its microstructure under optical microscope

Unetched mild steel --> you will not be able to see its microstructure under optical microscope.

The microstructure between etched mild steel and unetched mild steel does not change. Etching only to make the microstructure visible.

No

The etchings that are used for revealing microstructure of steel rods is to reveal the microstructure of the metal through the selective chemical attack. The procedure is carefully followed in order to reveal the accurate microstructures.

Eutectic steel is a type of steel that consists of two or more phases that solidify in a specific composition during cooling. Eutectoid steel, on the other hand, is a type of steel that undergoes a eutectoid transformation at a specific temperature, resulting in the formation of pearlite microstructure. Eutectoid steel has a single-phase microstructure, while eutectic steel has a multiphase microstructure.

The restoration mechanisms in metals are either dynamic recovery or dynamic recrystallization. These help to modify the microstructure by arranging line defects (dislocations) into surface defects (boundaries) thus ineffect reducing their spacing, and refining the microstructure.

Pearlite is a microstructure formed in steel with a specific carbon content, characterized by alternating layers of ferrite and cementite, while ledeburite is a less common microstructure formed at extremely high carbon levels, primarily composed of cementite and austenite, and is brittle in nature.

The eutectoid point of plain carbon steel is approximately 0.76% carbon content. At this composition, the steel undergoes a phase transformation from austenite to a mixture of ferrite and cementite during cooling, resulting in the formation of pearlite microstructure.

Grey cast iron is good for machine bases due to its capacity of absorbing vibration. This can be explained through its microstructure, where graphite works as great shock absorber.

The assessment of metallic alloy microstructure is not conducted by the application of volume fractions. Volume fractions, though applied to mixtures, are not appropriate in evaluating metallic crystal structures, even though there may be significant size differentials between the atoms of the metals in the alloy. Metallic crystal structures are evaluated by other methods (x-rays, electron microscopy, etc.) Got links if you want them. They are to related articles posted by our friends at Wikipedia, where knowledge is free.

A spectromicroscope combines microscopy and spectroscopy techniques to analyze samples at a microscopic level. It can provide information about the chemical composition, structure, and properties of the sample by generating spectroscopic data while visualizing the sample's microstructure.

Hypo-eutectic steel has a carbon content below the eutectic point, resulting in a microstructure with some ferrite and pearlite. Hyper-eutectic steel has a carbon content above the eutectic point, leading to a microstructure with primary cementite and pearlite.

Etchant is used in the microscopic examination of metal to reveal the microstructure of the metal, which helps in assessing its properties and quality. By selectively corroding different phases or constituents in the metal, etchant can highlight grain boundaries, inclusions, and other features that may affect the metal's mechanical properties. This process allows for better evaluation of the metal's structure and can provide insights into factors such as material composition, heat treatment, and processing history.

Heat Affected Zone (HAZ) is a rigion near the welded area, where microstructure shows distinct features of increase in grain size. This HAZ is normally suspetible to sensitization if the material is not stabilized or carbon content is high.

During quenching, austenite transforms into martensite through a rapid cooling process. This transformation involves the carbon atoms being trapped within the crystal lattice structure of the martensite, resulting in a hard and brittle microstructure.
