摘要:
提供一种以6000系铝合金板作为成形原材的使抗压特性提高的结构构件及其制造方法。即使将经由常规方法制造的、特定组成的6000系铝合金板作为原材使用,通过对其以冷加工很高地施加应变,从而提高人工时效处理后的结构构件表面的由X射线衍射测量的平均位错密度,也可使强度提高,并使由VDA弯曲试验评价的汽车的碰撞时的抗压特性提高。
摘要(英):
Disclosed are a structural part obtained from a 6000 series aluminum alloy sheet as a shaping raw material and having an improved crash performance; and a method for producing the sheet. For the sheet, a 6000 series aluminum alloy sheet is used which has a specified composition and is produced in the usual way. Even when this sheet is used, strain is given at a high level thereto by a cold work, thereby heightening the average dislocation density of a surface of the resultant structural part, which has been artificially aged. This density is measured by X-ray diffraction. Thus, the structural part is improved in strength and in crash performance, which is estimated in a VDA bending test, when the automobile collides.
