C&#039;est ainsi que vous ajustez la duret\u00e9, la r\u00e9sistance et la flexibilit\u00e9 de l&#039;acier selon vos besoins. Cette \u00e9tape vous permet de trouver le juste \u00e9quilibre, que vous fabriquiez des outils ou des lames. Les principales m\u00e9thodes de traitement thermique applicables \u00e0 l&#039;acier au carbone 1066 sont les suivantes\u00a0:<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Annealing\"><\/span><b>1. <\/b><b>Recuit<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Pour une meilleure maniabilit\u00e9 de votre acier 1066, le recuit est un bon point de d\u00e9part. Il est chauff\u00e9 au-dessus de la temp\u00e9rature critique, qui peut se situer entre 800 et 900 \u00b0C. Il refroidit ensuite lentement dans le four pour laisser agir son action. Cela lisse la structure interne de l&#039;acier. R\u00e9sultat\u00a0? Un mat\u00e9riau plus souple et beaucoup plus facile \u00e0 couper, \u00e0 fa\u00e7onner ou \u00e0 usiner.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Normalizing\"><\/span><b>2.<\/b> <b>Normalisation<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Pour normaliser votre acier, vous le chauffez l\u00e9g\u00e8rement plus que d&#039;habitude, entre 850 et 950 \u00b0C. Cela repr\u00e9sente environ 40 \u00b0C au-dessus de sa temp\u00e9rature critique sup\u00e9rieure. Une fois cette temp\u00e9rature atteinte, vous le laissez simplement refroidir naturellement \u00e0 l&#039;air libre. Ce traitement affine la structure du grain et am\u00e9liore les propri\u00e9t\u00e9s m\u00e9caniques, cr\u00e9ant ainsi un mat\u00e9riau plus uniforme et plus r\u00e9sistant que celui obtenu par recuit.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Quenching_and_Tempering\"><\/span><b>3.<\/b> <b>Trempe et revenu<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Pour durcir votre acier, vous devrez le soumettre \u00e0 un processus appel\u00e9 trempe.
