“…In addition, it has been reported that the precipitate formation is suppressed at high heating rates, and only the reverse martensite transformation can take place through the diffusionless mechanism [25]. It is clear that our results are in good agreement with the previous reports [24,25].…”

“…In contrast, the high volume fraction of soft reversed austenite associated with an ignorable amount of HCP‐ϵ martensite in sample 650 °C showed a tensile stress comparable to the as‐quench sample. The reason for this behavior could be laid in the fact that Mn as an essential element for solution hardening of matrix structure and formation of θ‐MnNi precipitates rejected into austenite phase during aging at 650 °C . However, a higher amount of reversed austenite in this condition caused to achieve higher elongation rather than as‐quenched sample.…”

“…A formação de uma estrutura em forma de lamelas é favorecida por poucos ciclos ou baixa temperatura intercrítica, enquanto ciclos altos ou altas temperaturas intercríticas induziriam uma esferoidização (GOLDBERG, 1968 FLOREEN, 1968). A austenita reversa pode aparecer como formas aciculares ou globulares, dependendo da taxa de aquecimento e da temperatura de revenimento (KIMMINS; GOOCH, 1983;SHIRAZI et al, 2013;ZHANG et al, 2018a). As ripas aciculares se formam na parte inferior do campo intercrítico, com baixas taxas de aquecimento.…”

“…As ripas aciculares se formam na parte inferior do campo intercrítico, com baixas taxas de aquecimento. A austenita globular se forma na porção mais alta do campo intercrítico e com altas taxas de aquecimento e, preferencialmente, forma-se no contornos dos pacotes de martensita ou no contorno de grão austenítico prévio (SHIRAZI et al, 2013;ZHANG et al, 2018a). Em ambos os casos, o processo de reversão pode levar ao refino da microestrutura (SHIRAZI et al, 2013;ZHANG et al, 2018a).…”
