Abstract
This work examines the effect of heat treatment on tensile strength and ductile
responses of rolled and forged AA6063 aluminum alloy. Some cast samples were
rolled while some were forged at ambient temperature (320C). The deformed
samples were subjected to heat treatment processes. The tensile strengths of rolled
(212 MPa) and forged (127 MPa) samples are enhanced at ambient temperature
but with poor elongation responses. A combination of improved strength and
elongation (127 MPa, 24%) can be obtained in rolled sample when solution heat
treatment (SHT) is applied after deformation and cooling in water. The forged
sample when homogenized, solution treated and water quenched has elongation of
about 24% with improved strength of 137 MPa. These results were obtained
because of the development of very fine AlFeSi texture in the matrix and along the
grain boundaries.
