Interpretation of the Microstructure of Steels

The microstructure is predominantly martensite but also has allotriomorphic ferrite, Widmanstätten ferrite, bainite and pearlite. Notice that the spherical shape of a pearlite colony is obvious in this sample because of the lack of impingment. Notice also that pearlite, unlike bainite, grows across the austenite grain boundaries.

Mill (currency) - Wikipedia

The term mill is often used in finance, particularly in conjunction with equity market microstructure. The term is sometimes used as one-hundredth of a cent. For example, a broker that charges 5 mils per share is taking in $5 every 10,000 shares traded. Additionally, in finance the term is sometimes spelled "mil".

Microstructures of Iron and Steels – IspatGuru

Mar 20, 2014· Microstructures of Iron and Steels The microstructures of iron and steels is complicated and diverse which is influenced by composition, homogeneity, heat treatment, processing and section size. Microstructure of castings looks different than those of the wrought products even if the composition is same and even if the same heat treatment is given.

Difference Between Hot Rolled Steel vs Cold Rolled Steel ...

Cold rolled steel is going to be stronger overall than hot rolled steel. Note that cold rolled steel has grains, while hot rolled steel does not. This is important because cold rolled steel is going to be strongest when it's laid with the grain, and is significantly weaker against the grain.

Failure of high-chromium iron roll in compact strip ...

No abnormalities with respect to the mill process conditions have occurred prior to and during the roll failure. The chromium content in the core is far in excess of the limit defined for the mill (max 0.50%Cr). As a result, the microstructure contains abundant millimeter-sized carbide clusters, leading to a poor impact strength of the core.

Microstructure - Wikipedia

Microstructure is the very small scale structure of a material, defined as the structure of a prepared surface of material as revealed by an optical microscope above 25× magnification. The microstructure of a material (such as metals, polymers, ceramics or composites) can strongly influence physical properties such as strength, toughness, ductility, hardness, corrosion resistance, high/low ...

During hot rolling the microstructure and mechanical properties of the material change with its thermomechanical state, determined by composition, percent reduction, strip thickness, strip speed, and heat transfer. For steels, hot rolling is generally conducted at 850–1200 °C, in the austenite phase, while for aluminum it is conducted at 350–500 °C.
