“…10. Within the spray formed materials vanadium containing precipitates were identified by means of electron microprobe investigation, which were not observed for the other materials and may be explained by a higher thermal stability of vanadium carbonitrides in comparison to vanadium carbides during heat treatment [28]. Carbonitrides, especially at grain boundaries, are expected to reduce toughness.…”

“…Hence, excess normalizing temperatures should be avoided. According to Goldshtein and Popov [21,22], V and Nb carbides dissolve readily in steel at temperatures of 1,000-1,050°C. Ennis et al [11] showed that higher normalizing temperatures led to an increase in grain size and reported optimum normalizing temperature as 1,070°C.…”

“…Outros efeitos como a concentração de hidrogênio, as tensões residuais e a temperatura (entre -60 ºC e 150 o C) também influenciam na ocorrência deste tipo de defeito [16]. maior ou menor escala, conforme a temperatura atingida e o tempo na temperatura [23,24], os carbonetos e nitretos que precipitam nos contornos de grão e no interior dos grãos, são quase que totalmente dissolvidos [22,25,26]; a fração volumétrica de perlita ou de agregados ferrita/cementita tende a zero e a deformação plástica residual é toda eliminada. Em outras palavras, a microestrutura é completamente alterada e, dependendo da velocidade de resfriamento se transforma em fase dura, resistente e pouco tenaz, a martensita.…”
