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.
In strain hardening hypothesis, the size of the yield locus is assumed to beindependent of the third invariant.In work hardening hypothesis, the size of the yield locus is assumed to depend on the total plastic work done (per unit volume) to achieve the present state of plastic deformation since last annealinfor isotropic hardening Both are same.

Case hardening, also referred to as surface hardening is the process of hardening a surface of a metal. It is done by surfacing the metal surface with a layer of metal on top of it, in order to harden it.
The term means "hardening" of the "drum". In this case, it is meant that the inner ear is calcified.
mostly is the hardening done by induction hardening machine, I know also manufactures that do this using the flame hardening method.
in my opinion surface hardening is applied only on the surface while the true hardening is applied in the whole part of the metal....
Arteriosclerosis is hardening of the arteries.
what the was on tooth hardening day?
Simply, introduces a higher carbon concentration into the surface of relatively low carbon steels. Enables "case hardening".
Sclero means a hardening from the greek word "skleros". Sclerosis means a hardening of the skin.
Glomerulosclerosis means hardening of the glomerulus.
Case hardening is a heat treatment process used to harden the surface of a metal while maintaining a softer, ductile interior. This is typically achieved through methods like carburizing, nitriding, or carbonitriding, where carbon or nitrogen is introduced into the surface layer of the metal at high temperatures. The primary purpose is to enhance wear resistance and fatigue strength, making components more durable in high-stress applications, such as gears and bearings. By hardening the surface, the underlying material retains its toughness, preventing brittleness and failure.
Core hardening refers to the innermost portion of metal. When the outer layer remains soft, but the inner portion is hardened, this is core hardening.
No hydrogenating is the absorption of water, hardening is the process of something getting harder.
