Abstract

processo de elaboração de um aço martensítico, aço martensítico, peça de aço martensítico, e, árvore de trasmissão em aço martensítico a invenção se refere a um processo de elaboração de um aço martensítico que comporta teores de outros metais tais que é apto a ser endurecido por uma precipitação de compostos intermetálicos e de carbonetos, com um teor de ai compreendido entre 0,4% e 3%. a temperatura de formatação a quente do último ciclo de formatação à quente deste aço é inferior à temperatura de solubilidade dos nítretos de alumínio neste aço, e a temperatura de tratamento cada um dos eventuais tratamentos térmicos de acordo com este últüno ciclo de formatação à quente é inferior à temperatura de solubilidade no estado sólido dos nitretos de alumínio neste aço.
