- The mobility-suppressing transition faster than relaxation is the load-bearing condition: cooling must proceed faster than the crystallization rate, which for many alloys means quench rates of \(10^5\)–\(10^6\) K/s, so that the temperature drops through the glass-transition before diffusion can nucleate and grow crystals.

The abstract states the qualitative principle only - amorphous configurations retained by cooling the melt with sufficient celerity to prevent crystallization - not the 10^5-10^6 K/s range or a glass-transition mechanism.
“For some metalloids, the bonding of which may actually be more covalent than metallic, such amorphous configurations have been retained in the solid state 2 by cooling from the melt with sufficient celerity so as to prevent formation of the equilibrium crystalline structures.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
