Abstract

resumo membro oco tubular e método para a formação de um membro oco tubular um membro oco tubular, ao qual a torção sobre uma linha central é aplicada, é caracterizado pela realização de um tratamento térmico parcial na parte da parede periférica do membro oco para tornar a dureza da parte externa da parede periférica maior do que a dureza antes de aquecê-la e maior do que a dureza da parte interna da parede periférica, e reduzir a tensão residual da parte interna da parede periférica. 1/1
