Definitions

  • M is the Taylor factor
  • ⁇ CRSS is the critical resolved shear stress of crystal.
  • the Taylor factor M is a constant corresponding to the crystal orientation, reaches a maximum of 3.674 when the tension axis is in parallel with [110] and [111], and reaches 2.449, near to the minimum 2.300, when the tension axis is in parallel with [100].
  • the critical resolved shear stress ⁇ CRSS has a constant value. It has been pointed out that the bending workability correlates with the Taylor factor.
  • the 6000-series aluminum alloy extrudate (or the cast billet as a raw material thereof) to which the present invention is applied is an Al—Mg—Si aluminum alloy containing, as its chemical composition in percent by mass, Mg in a content of from 0.60% to 1.20%, Si in a content of from 0.30% to 0.95%, Fe in a content of from 0.01% to 0.40%, Mn in a content of from 0.30% to 0.52%, Cu in a content of from 0.001% to 0.65%, and Ti in a content of from 0.001% to 0.10%, the contents of Mg and Si satisfying the condition: [Mg (%)] ⁇ (1.73 ⁇ [Si (%)] ⁇ 0.25) ⁇ 0, with the remainder including Al and inevitable impurities.
  • the temperature of the extrudate at the extruder exit refers to the temperature of the extrude surface immediately downstream from the die exit (at a distance of 0 mm from the exit).
  • the aforementioned temperature may be determined by measuring the temperature of the extrudate surface at a certain distance from the die exit (the position where temperature measurement can be performed varies depending on the extrusion press to be used) with a contact type thermometer; and, from the measured temperature, calculating backward the temperature immediately downstream from the die exit using a cooling curve of the extrudate which has been measured in advance.
  • the T5 refining treatment saves post-extrusion steps such as reheating, solution treatment, and quenching for the extrudate.
  • the T5 refining treatment may be replaced by the T6 refining treatment which includes separate reheating of the extrudate after hot extrusion to 500° C. or higher, and subsequent solution treatment, quenching, and artificial aging treatment, to give a T6 refining extrudate.
  • the present invention provides the 6000-series aluminum alloy extrudate and the manufacturing method thereof, which extrudate has both good bending crush resistance and good corrosion resistance required of reinforcements for automotive bodies.
  • the extrudate is suitable for use as automotive body reinforcements, such as bumper reinforcements and door guard bars, which need outstanding transverse crushing performance.
