Short answer: Microalloying adds tiny amounts of niobium, vanadium, titanium or boron to steel to refine grains and precipitate hard particles — giving high strength and toughness without the cost or weld problems of heavy quenching and tempering.

Domande frequenti
Adding very small amounts of Nb/V/Ti/B to strengthen steel via grain refinement and precipitation.
It refines grains and raises strength while keeping weldability.
It precipitates carbides for precipitation hardening in rebar and forgings.
Lower carbon avoids the hard zones of quenched-and-tempered steel.
