Abstract

"TRATAMENTO TéRMICO DE PRODUTO DE LIGA DE TITâNIO QUE TENHA ESTRUTURA MARTENSìTICA". A invenção refere-se a um produto formado de uma liga com base de titânio alfa-beta, preferivelmente uma liga que tenha mais que cerca de 3,5 por cento em peso de molibdênio. Um exemplo de tal produto é uma lâmina de compressor de turbina a gás (20) tendo uma composição nominal, em peso percentual, de cerca de 4 por cento de alumínio, cerca de 4 por cento de molibdênio, cerca de 2 por cento de estanho, cerca de 0,5 por cento de silício, o saldo sendo titânio e impurezas. O produto é processado para formar uma estrutura martensítica. O processamento, que envolve tipicamente o forjamento ou o reparo com solda, inclui as etapas de aquecer primeiramente o produto até uma primeira temperatura de aquecimento maior que cerca de 871,1<198>C (1600<198>F), e então resfriar primeiramente o produto até uma temperatura de menos que cerca de 426,7<198>C (800<198>F). O produto é então aquecido pela segunda vez até uma segunda temperatura de aquecimento de cerca de 690,6<198>C (1275<198>F) até cerca de 746,1<198>C (1375<198>F) por um tempo cerca de 1 até cerca de 7 horas, e então resfriado pela segunda vez até uma temperatura de menos de cerca de 426,7<198>C (800<198>F) a uma segunda taxa de resfriamento que não exceda cerca de -9,4<198>C (15<198>F) por segundo.
