Metallilangat

Metallilangat is a term that does not have a formal definition in established scientific literature. It appears primarily in Indonesian-language online discussions and speculative fiction as a coined word rather than a recognized technical term.

In its common informal usage, metallilangat refers to a hypothetical or fictional process involving metals in which part of a metallic structure can detach, rearrange, or release energy under certain triggers. The concept is typically described in worldbuilding contexts or thought experiments about advanced materials, nanostructures, or self-transforming metals.

Origins and usage vary by author; the term is a neologism created by combining "metal" with a local-language element. It is not used in peer-reviewed metallurgy or materials science, and there is no experimental evidence for metallilangat as it appears in fiction.

Relation to real science: While it is sometimes used to illustrate ideas reminiscent of phase transformations, self-healing materials, or programmable metamaterials, metallilangat as a defined process is not an established mechanism. Real research in metallurgy and materials science investigates mechanical failure, fatigue, corrosion, and structural reconfigurability through legitimate mechanisms, not a universal phenomenon called metallilangat.
