The combination of a hard surface and a soft interior is greatly valued in modern metal engineering because it offers very high stress and fatigue for applications such as gears and anti-friction bearings. Surface-hardened steel is also valued for its low cost and superior flexibility in manufacturing.
The features that form as a result of magma of magma hardening beneath the earth's surface are volcanic necks,sills and batholiths.
To increase the melting point of aluminium, (and treating this as a philosophical question), then hardening the 'crystal matrix' may be one approach. Surface hardening by work hardening, or perhaps by inserting nitrogen ions into the surface as is used in metal(ferrous) hardening.
Igneous rocks are formed by the cooling and hardening of molten material called magma.
Intrusive igneous rocks such as dikes, sills, and batholiths are formed from the cooling and hardening of magma beneath Earth's surface. These structures are formed when magma solidifies underground, creating features like vertical dikes, horizontal sills, and large masses of magma called batholiths.
Hardening of the cells is called sclerosis. This term is commonly used in medical contexts to describe the process of abnormal thickening, hardening, and scarring of tissues.
in my opinion surface hardening is applied only on the surface while the true hardening is applied in the whole part of the metal....
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.
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.

mostly is the hardening done by induction hardening machine, I know also manufactures that do this using the flame hardening method.
Simply, introduces a higher carbon concentration into the surface of relatively low carbon steels. Enables "case hardening".

No, a rock with visible layers and no minerals is more likely to be a sedimentary rock formed from the accumulation and compaction of sediments over time. Lava hardening on the Earth's surface tends to form igneous rocks with a different texture and composition.
what the was on tooth hardening day?
