Equil\u00edbrio de fase da soldagem de tubos de a\u00e7o inoxid\u00e1vel duplex<\/h2>\n

Diz-se frequentemente que o balan\u00e7o de fase do a\u00e7o inoxid\u00e1vel duplex \u00e9 \"50-50\", o que equivale \u00e0 quantidade de austenita e ferrita. A rigor, isto \u00e9 incorreto porque o conte\u00fado de ferrite em a\u00e7o inoxid\u00e1vel duplex moderno \u00e9 cerca de 40% -50%, e o restante \u00e9 austenita.<\/p>\n

\"Balan\u00e7o<\/a><\/p>\n

Em geral, acredita-se que quando o teor de ferrita \u00e9 de pelo menos 25-30% e o resto \u00e9 austenita, tubo duplex<\/a> tem vantagens \u00fanicas.<\/p>\n

Em alguns m\u00e9todos de soldagem, especialmente no m\u00e9todo de prote\u00e7\u00e3o do fluxo para tubo duplex 2205<\/a>, ajustando o equil\u00edbrio de fase, o teor de austenita na solda pode atingir um n\u00edvel mais alto, melhorando assim a tenacidade da solda e compensando o teor de oxig\u00eanio da solda causado pelo fluxo Aumento da perda de tenacidade.<\/p>\n

A tenacidade desses metais de adi\u00e7\u00e3o ap\u00f3s o tratamento em solu\u00e7\u00e3o \u00e9 muito menor do que a das placas de a\u00e7o ou tubos de a\u00e7o, mas a tenacidade do metal de solda ainda \u00e9 suficiente para atender aos requisitos esperados.<\/p>\n

Nenhum m\u00e9todo de soldagem pode fazer a tenacidade do metal de solda atingir a altura do metal forjado ap\u00f3s o recozimento completo. Se o teor de ferrite do metal de solda for limitado ao m\u00ednimo necess\u00e1rio para o recozimento do a\u00e7o inoxid\u00e1vel duplex no laminador, o m\u00e9todo de soldagem dispon\u00edvel imp\u00f5e restri\u00e7\u00f5es desnecess\u00e1rias.<\/p>\n

O equil\u00edbrio de fase da zona afetada pelo calor, ou seja, o a\u00e7o forjado original ou tubo de a\u00e7o inoxid\u00e1vel<\/a> al\u00e9m de um ciclo de calor de soldagem adicional, geralmente \u00e9 um pouco maior do que o material original. \u00c9 quase imposs\u00edvel determinar o equil\u00edbrio de fase da zona afetada pelo calor pelo m\u00e9todo metalogr\u00e1fico.<\/p>\n

Se o teor de ferrita nessa regi\u00e3o for alto, isso pode indicar uma condi\u00e7\u00e3o anormal de resfriamento extremamente r\u00e1pido, o que resulta em teor excessivo de ferrita e tenacidade reduzida.<\/p>\n
