ulekuumenemine
Ulekuumenemine refers to the process of heating a solid material above its melting point and then rapidly cooling it to a temperature below its solidification point. This rapid cooling, often achieved by plunging the heated material into a quenching medium such as water, oil, or brine, prevents the formation of stable crystalline structures. Instead, the material solidifies into a metastable, amorphous, or glassy state.
This technique is commonly employed in materials science and metallurgy, particularly for producing metallic glasses or
The term itself is a neologism, combining "ule" (meaning "above") and "kuumenemine" (meaning "heating") with "emine"
