本文通过晶粒度有代表性的七根六二黄铜波导,系统地探索了“桔子皮”现象的产生和发展规律。指出了“桔子皮”现象的本质;对不同退火温度下的“桔子皮”程度作了定量描述,为合理制定退火工艺提供了依据。本文还为波导成形后的外观检验,提出了可资参考的经验公式,为鉴别波导原材料质量的优劣,提供了判据。 In this paper, we systematically explored the law of generation and development of “orange peel” through seven representative sixty-two brass waveguides with grain size. The essence of “orange peel” phenomenon is pointed out. The quantitative description of “orange peel” under different annealing temperature provides a basis for the reasonable formulation of annealing process. The paper also presents the empirical formula for the visual inspection after waveguide shaping, which provides the criterion for the identification of the quality of waveguide raw materials.
