Metallurgy Of Carbon Steel - gowelding

A fully pearlitic structure occurs at 0.8% Carbon. Further increases in carbon will create cementite at the grain boundaries, which will start to weaken the steel. Cooling of a steel below 0.8% carbon When a steel solidifies it forms austenite. When the temperature falls below the A3 point, grains …

The Characteristics of Austenitic Stainless Steel

This grain structure forms when a sufficient quantity of nickel is added to the alloy—8 to 10 percent in a standard 18 percent chromium alloy. In addition to being non-magnetic, austenitic stainless steels are not heat treatable. They can be cold worked to improve hardness, strength, and stress resistance, however.

GRAIN STRUCTURE - the-warren

The advantage is that the part can be formed without annealling and the grain structure will follow the form of the object being forged. So for example a spanner would have a central part where the grain structure is elongated but with few dislocations then the grain flows around following the …

Smaller the grain structure higher is the grain interaction with each other and higher is the interaction energy. Higher the contact surface area results in the best adhesion, in this case, the crystallite bonding with each other. So in short smaller the grain size higher will be the mechanical properties.

In ferritic steels there is a transformation from the body-centered-cubic lattice structure of ferrite to the face-centered-cubic lattice structure of austenite. The temperature of this transformation depends upon the composition but is about 1340o F for a plain-carbon steel similar to the SA178 or SA210 grades.

Metallurgy Matters The structure of metal

Grain boundaries form a continuous network throughout the metal, and because of the disrupted structure at the boundary, the metal often acts differently at the boundary locations. Grain boundaries aside, each grain in a pure metal has the same crystalline structure as any other grain, assuming the temperature is the same.
