Description
The effects of niobium on the austenite decomposition of a chromium steel was determined by continuous cooling experiments. Niobium retards appreciably the anisothermic decomposition of austenite with increasing cooling rates. The influence of niobium is discussed considering its possible segregation to austenitic grain-boundaries and its strong interactive attraction to carbon. (Author)

O efeito do niobio na decomposicao da austenita em um aco ao cromo foi determinada por experiencias de resfriamento continuo. O niobio retardou apreciavelmente a decomposicao anisotermica da austenita com o aumento da taxa de resfriamento. A influencia do niobio e discutida considerando sua possivel segregacao nos contornos intergranulares da austenita e de sua forte interacao atrativa com o carbono. (Autor)Files
