\u00a0 \u00a0 \u00a0 A liga Inconel718 \u00e9 uma liga de n\u00edquel-ferrocromo endurecida por precipita\u00e7\u00e3o que cont\u00e9m ni\u00f3bio e molibd\u00e9nio. Tem uma elevada resist\u00eancia, boa tenacidade e resist\u00eancia \u00e0 corros\u00e3o a baixas temperaturas inferiores a 650\u00b0C. O estado pode ser um tratamento de solu\u00e7\u00e3o s\u00f3lida ou um estado endurecido por precipita\u00e7\u00e3o.<\/span><\/p>\n

IV. Carater\u00edsticas do material Inconel718<\/span><\/strong><\/p>\n

    \n
  • Facilmente process\u00e1vel<\/span><\/li>\n
  • Possui elevada resist\u00eancia \u00e0 tra\u00e7\u00e3o, resist\u00eancia \u00e0 fadiga, resist\u00eancia \u00e0 flu\u00eancia e resist\u00eancia \u00e0 fratura a 700\u00b0C<\/span><\/li>\n
  • Elevada resist\u00eancia \u00e0 oxida\u00e7\u00e3o a 1000\u00b0C<\/span><\/li>\n
  • Propriedades qu\u00edmicas est\u00e1veis a baixas temperaturas<\/span><\/li>\n
  • Bom desempenho de soldadura<\/span><\/li>\n<\/ul>\n

    5. Estrutura metalogr\u00e1fica do Inconel718<\/span><\/strong><\/p>\n

    A liga GH4169 tem uma estrutura de austenite, e a fase \u03b3 gerada ap\u00f3s a precipita\u00e7\u00e3o e o endurecimento confere-lhe excelentes propriedades mec\u00e2nicas. A fase \u03b4 gerada no limite do gr\u00e3o durante o tratamento t\u00e9rmico confere-lhe a melhor plasticidade.<\/span><\/p>\n

    6. Resist\u00eancia \u00e0 corros\u00e3o do Inconel718<\/span><\/strong><\/p>\n

    A liga Inconel718 tem uma excelente resist\u00eancia \u00e0 fissura\u00e7\u00e3o por corros\u00e3o sob tens\u00e3o e \u00e0 corros\u00e3o por picadas, independentemente do ambiente de alta ou baixa temperatura. A liga Inconel718 tem uma excelente resist\u00eancia \u00e0 oxida\u00e7\u00e3o a altas temperaturas<\/span><\/p>\n

    7. Dom\u00ednios de aplica\u00e7\u00e3o<\/span><\/strong><\/p>\n

    Devido \u00e0 sua resist\u00eancia a altas temperaturas, excelente resist\u00eancia \u00e0 corros\u00e3o e f\u00e1cil processamento a 700\u00b0C, pode ser amplamente utilizado em v\u00e1rias ocasi\u00f5es de elevada procura.<\/span><\/p>\n
