搅拌摩擦加工（FSP）可用于局部改变铝的材料性质，例如延展性。1，2由于FSP产生细晶粒显微组织和局部退火，延展性增加。这使得FSP能够局部改善铝的可成形性，而铝的可成形性通常是有限的。典型地，对于铝制造，这导致成形部件的有限使用。此外，这种可成形性的缺乏导致复杂形状的铝制品主要由扁平部件或最小成形部件组成。这导致了对连接操作的过度需求。3或者，FSP可用于零件成型，减少零件数量和后续连接。一个这样的示例是在由铝板制造的角或C形通道的制造中。本文将描述在AA 5083-H116上使用FSP形成角度或C形通道的鉴定程序的一小部分结果。机械性能测试结果的摩擦搅拌加工，摩擦搅拌焊接，气体保护金属电弧焊，并在成形和未成形的条件下的基础材料将被提交。
Friction Stir Processing (FSP) can be used to locally modify material properties of aluminum such as ductility. 1, 2 Ductility is increased due to FSP creating a fine grain microstructure and local annealing. This allows FSP to locally improve the formability of aluminum, which normally is limited. Typically, for aluminum fabrications, this results in limited use of formed components. Furthermore, this lack of formability results in complex shaped aluminum fabrications to be composed primarily of flat components or minimally formed components. This results in the excessive need for joining operations. 3 Alternatively, FSP can be used to enable forming of parts, reducing both the number of detail parts and subsequent joining. One such example is in the fabrication of angles or C-channels fabricated from aluminum plate. This paper will describe a small subset of results of a qualification program for the use of FSP on AA5083-H116 to form angles or C-channels. Mechanical property test results on friction stir processed, friction stir welded, gas metal arc welded, and base material in both formed and unformed conditions will be presented.
