Abstract:
This study was undertaken to investigate the effect of Al–5Ti–1B and Al–15Zr master alloys on the structural characteristics and tensile properties of extruded AA2014 aluminum alloy. The results revealed that the optimum Ti and Zr contents to achieve a fine-grained were found to be 0.03 wt.% and 0.5 wt.%, respectively. The average grain size decreased from 1000 μm to 162 μm and 203 μm,respectively with adding 0.03 wt.%Ti and 0.5 wt.% Zr. The results of tensile testing of the extruded specimens showed enhanced ultimate tensile strength (UTS) and elongation (%El) values of the 2014 alloy after Ti and Zr additions in optimum levels. Furthermore, with adding 0.5 wt.%Zr, tensile strength and elongation values of the extruded refined sample increased from 282 MPa and 12% to 379 MPa and17%, respectively. Also, with adding 0.03%Ti, tensile strength values of the extruded refined samplewere enhanced from 282 MPa to 370 Mpa, but elongation decreased from 12% to 8%. This could be attributed to uniform distribution of Al3Zr & Al3Ti particles in the α-Al matrix and the breakdown of Ɵ & S phases by applying of extrusion process
