| dc.description | The research of rare earths for the synthesis of materials with improved mechanical
performance is of great interest when they are considered for potential applications in the
automotive industry. In this regard, the effect on the mechanical properties and
microstructure of the automotive A356 aluminum alloy reinforced with 0.2 (wt.%) Al-6Ce-
3La (ACL) was investigated. The ACL was added to the melted A356 alloy in the 1) asreceived
condition and 2) processed by mechanical milling. In the second route, the effect
of the ACL processed by mechanical milling and powder metallurgy techniques was
investigated, and compared with the results obtained from the A356 alloy strengthened
with ACL in the as-received condition. Microstructural properties were evaluated by
means of X-ray diffraction in order to observe the solubility of Ce/La in the Al matrix. In
addition, electron microscopy was employed in order to investigate the effect of milling
time on the size and morphology of La/Ce phase under milling process. Mechanical
properties of the A356 alloy modified with ACL were measured by hardness and tensile
test. For comparison unmodified specimens of the A356 were characterized according to
the previous procedure. The microstructural and mechanical characterization was carried
out in specimens after solution and artificial aging. Observations in scanning electron
microscopy indicate a homogeneous dispersion of La/Ce phases by using both routes;
however, mechanical results, in the modified A356 alloy with the ACL in the as-received
condition, show an improvement in the mechanical performance of the A356 alloy over
that reinforced with the ACL mechanically milled.</�������� | |
