What is case hardening?
Case hardening or surface hardening is the process of hardening the surface of a metal, often a low carbon steel, by infusing elements into the material's surface, forming a thin layer of a harder alloy.
Does hardening of steel make it ductile or brittle?
more brittle

Martensite

What is the full form of OHNS?
oil hardening non shrinkable stainless steel
What are didadvantages of titanium?
Titanium is relatively expensive, work hardening, and softer then steel.
Why does hardened steel rust faster?
Hardened steel can rust faster than regular steel because the hardening process can disrupt the steel's natural corrosion resistance. This can lead to increased vulnerability to rust and other forms of deterioration. Hardened steel may also have more exposed surface area due to the hardening process, which can make it more prone to rusting.
Is the steel strain hardening exponent temperature dependent?
yes, with increased temp, the s.h.e decreaseshiAccording to your answer . I must say that as I know , when we anneald metals ( e.g. Iron ) the S.H.E increased while you can decreas it by cold-work .
Is Surface hardening better method to use or Annealing when these methods are used to manufacture products from ferrous metals?
These are two different methods that are opposites. Surface hardening is used to stiffen a steel. Usually a steel is heated, a catalyst is applied to the surface and then the steel is quenched in an oil bath or waterbath, this hardens the surface of the steel. Annealing on the other hand, the steel is heated and then allowed to cool slowly. This softens the steel and allows it to be drawn or hammered to form a different shape.
What is strain hardening of steel?
Strain hardening, also known as work hardening, is the process by which steel becomes stronger and harder as it is deformed plastically. During this process, the dislocation density within the material increases, making further deformation more difficult. This phenomenon occurs when steel is subjected to processes like bending, stretching, or forging, resulting in improved tensile strength and hardness. However, it can also reduce ductility, making the material more brittle.
Will casein stick to steel when hardening?
Yes, casein can stick to steel when hardening, particularly if it is applied as a paint or adhesive. The bonding occurs due to the protein's ability to create a film that adheres to the metal surface. However, the effectiveness of the bond can depend on the surface preparation of the steel and environmental factors like temperature and humidity during the curing process. Properly preparing the steel surface can enhance adhesion.
