摘要： An aluminum alloy-based extruded flat tube having the increased proof strength and pressure-resistant strength is disclosed. An aluminum alloy-based extruded multi-path flat tube that is obtained by extruding an aluminum alloy billet is subjected to the low strain working at the low strain of 2% to 15% prior to the brazing process. After the flat tube is brazed, it may have the organization that includes the surface layer containing equal to 5% or more than 5% of non-recrystallized grains and the inner layer containing equal to 30% or more than 30% of recrystallized grains. The strain may be expressed as (1−H/H0) * 100%, for example, in which H0 refers to the height of the flat tube prior to low strain working process, and H refers to the height of the flat tube after the low strain working process is completed. The proof strength can be increased by the non-recrystallized grains contained in the surface layer 1a and in the surface layer 2a in the path of fluid passage. The reduction in the strength that might be caused by the filler erosion can be prevented as the filler erosion is restricted by the recrystallized grains contained in the inner layer 1b.
摘要翻译：公开了一种具有提高的抗强度和耐压强度的铝合金基挤压扁管。在钎焊过程之前，通过挤压铝合金坯获得的铝合金挤压多径扁平管在2％〜15％的低应变下进行低应变加工。在扁平管钎焊之后，可能具有包括含有等于5％或5％以上的未再结晶晶粒的表面层和含有等于30％或30％以上的再结晶晶粒的内层的组织。该应变可以表示为（1-H / H 0 O）* 100％，例如，其中H <0 是指低管之前的扁平管的高度应变加工过程中，H是指低应变加工完成后扁管的高度。可以通过表面层1a中所含的未再结晶晶粒和流体通路中的表面层2a中的强度来提高检验强度。由于填充物侵蚀受到内层1b中所含的再结晶晶粒的限制，可以防止可能由填料侵蚀引起的强度的降低。
