  2. Non-metallic inclusions - Wikipedia

    en.wikipedia.org/wiki/Non-metallic_inclusions

    Inclusions are present in any steel to a greater or lesser extent according to the mixture and conditions of production. Usually the amount of non-metallic inclusions in steel is not higher than 0.1%. However, the number of inclusions in metal is very high because of their extremely small size. Non-metallic inclusions in steel are foreign ...

  3. Deoxidization - Wikipedia

    en.wikipedia.org/wiki/Deoxidization

    If steel is not properly deoxidized, it will have lost various properties such as tensile strength, ductility, toughness, weldability, polishability, and machinability. This is due to forming non-metallic inclusions and gas pores , bubbles of gas that get trapped during the solidification process of steel.

  4. Stress concentration - Wikipedia

    en.wikipedia.org/wiki/Stress_concentration

    In practice, however, material inconsistencies such as internal cracks, blowholes, cavities in welds, air holes in metal parts, and non-metallic or foreign inclusions can occur. These defects act as discontinuities within the component, disrupting the uniform distribution of stress and thereby leading to stress concentration.

  5. Deoxidized steel - Wikipedia

    en.wikipedia.org/wiki/Deoxidized_steel

    Note that decrease in carbon content increases the problems with non-metallic inclusions. [7] [needs update] Continuous casting and strip-casting technologies have largely superseded ingot casting techniques in recent times. Through these methods, all steel is killed and the resulting yields are close to 96%.

  6. Acicular ferrite - Wikipedia

    en.wikipedia.org/wiki/Acicular_ferrite

    This microstructure is advantageous over other microstructures for steel because of its chaotic ordering, which increases toughness. [ 1 ] Acicular ferrite is formed in the interior of the original austenitic grains by direct nucleation on the inclusions, resulting in randomly oriented short ferrite needles with a 'basket weave' appearance.

  9. Rolling-element bearing - Wikipedia

    en.wikipedia.org/wiki/Rolling-element_bearing

    A sealed deep groove ball bearing. In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, [1] is a bearing which carries a load by placing rolling elements (such as balls, cylinders, or cones) between two concentric, grooved rings called races.
