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.
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.
The features that form as a result of magma of magma hardening beneath the earth's surface are volcanic necks,sills and batholiths.
Plutons
Igneous rocks are formed by the cooling and hardening of molten material called magma.
sclerite
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.

Simply, introduces a higher carbon concentration into the surface of relatively low carbon steels. Enables "case hardening".
