Abstract

"MéTODO DE RESFRIAMENTO BRUSCO DE UMA CHAPA DE LIGA PARA MINIMIZAR DISTORçõES". Um método de produção de um produto chapa ou outro produto alongado de liga de alumínio tratada termicamente em solução substancialmente livre de distorções térmicas permanentes. O método compreende submeter um produto feito de uma liga de alumínio tratada termicamente a um tratamento térmico em solução a uma temperatura de tratamento térmico em solução para dissolver os precipitados solúveis presentes na liga, resfriando-se o produto da temperatura do tratamento térmico em solução até uma temperatura crítica superior abaixo da qual a precipitação de partículas da segunda fase pode ocorrer e posteriormente resfriar o produto até uma temperatura crítica inferior abaixo da qual a precipitação de partículas da segunda fase pode não mais ocorrer, o resfriamento ocorrendo entre as temperaturas críticas superior e inferior a uma taxa de resfriamento suficientemente rápida para evitar uma precipitação significativa a partir da liga, e opcionalmente resfriando-se adicionalmente o produto até uma temperatura abaixo da temperatura crítica inferior. O resfriamento posterior do produto é executado de tal forma que a taxa de resfriamento aumenta à medida que o resfriamento progride.
