Effect of Growth Rate on the Microstructure and Microhardness in a Directionally Solidified Al-Zn-Mg Alloy
Abstract The Al-5.5Zn-2.5Mg (wt pct) ternary alloy was prepared using a vacuum melting furnace and a casting furnace. Five samples were directionally solidified upwards at a constant temperature gradient (G = 5.5 K/mm) under different growth rates (V = 8.3–165 μm/s) in a Bridgman-type directional so...

| 520 | |a Abstract The Al-5.5Zn-2.5Mg (wt pct) ternary alloy was prepared using a vacuum melting furnace and a casting furnace. Five samples were directionally solidified upwards at a constant temperature gradient (G = 5.5 K/mm) under different growth rates (V = 8.3–165 μm/s) in a Bridgman-type directional solidification furnace. The primary dendrite arm spacing, λ1, secondary dendrite arm spacing, λ2, and microhardness, HV, of the samples were measured. The effects of V on λ1, λ2 and HV properties of the Al-Zn-Mg alloy were studied by microstructure analysis and mechanical characterization. Microstructure characterization of the alloys was carried out using optical microscopy, scanning electron microscopy, wavelength-dispersive X-ray fluorescence spectrometry, and energy dispersive X-ray spectroscopy. From the experimental results, it is found that the λ1, λ2 values decrease, but HV values increase with the increase in V, and HV values decrease with the increase in λ1 and λ2. Dependencies of dendritic spacing and microhardness on the growth rate were determined using linear regression analysis. The growth rate, microstructure, and Hall–Petch-type relationships obtained in this work have been compared with the results of previous studies. | ||

Five samples were directionally solidified upwards at a constant temperature gradient (G = 5.5 K/mm) under different growth rates (V = 8.3–165 μm/s) in a Bridgman-type directional solidification furnace. The primary dendrite arm spacing, λ1, secondary dendrite arm spacing, λ2, and microhardness, HV, of the samples were measured. The effects of V on λ1, λ2 and HV properties of the Al-Zn-Mg alloy were studied by microstructure analysis and mechanical characterization. Microstructure characterization of the alloys was carried out using optical microscopy, scanning electron microscopy, wavelength-dispersive X-ray fluorescence spectrometry, and energy dispersive X-ray spectroscopy. From the experimental results, it is found that the λ1, λ2 values decrease, but HV values increase with the increase in V, and HV values decrease with the increase in λ1 and λ2. Dependencies of dendritic spacing and microhardness on the growth rate were determined using linear regression analysis. The growth rate, microstructure, and Hall–Petch-type relationships obtained in this work have been compared with the results of previous studies.

Five samples were directionally solidified upwards at a constant temperature gradient (G = 5.5 K/mm) under different growth rates (V = 8.3–165 μm/s) in a Bridgman-type directional solidification furnace. The primary dendrite arm spacing, λ1, secondary dendrite arm spacing, λ2, and microhardness, HV, of the samples were measured. The effects of V on λ1, λ2 and HV properties of the Al-Zn-Mg alloy were studied by microstructure analysis and mechanical characterization. Microstructure characterization of the alloys was carried out using optical microscopy, scanning electron microscopy, wavelength-dispersive X-ray fluorescence spectrometry, and energy dispersive X-ray spectroscopy. From the experimental results, it is found that the λ1, λ2 values decrease, but HV values increase with the increase in V, and HV values decrease with the increase in λ1 and λ2. Dependencies of dendritic spacing and microhardness on the growth rate were determined using linear regression analysis. The growth rate, microstructure, and Hall–Petch-type relationships obtained in this work have been compared with the results of previous studies.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Directional Solidification</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Mushy Zone</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Primary Dendrite</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Dendritic Spacing</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Dendrite Core</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Çadırlı, Emin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Erol, Harun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gündüz, Mehmet</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Metallurgical and materials transactions</subfield><subfield code="d">Boston : Springer, 1975</subfield><subfield code="g">47(2016), 6 vom: 08.

Effect of Growth Rate on the Microstructure and Microhardness in a Directionally Solidified Al-Zn-Mg Alloy |
| abstract |
Abstract The Al-5.5Zn-2.5Mg (wt pct) ternary alloy was prepared using a vacuum melting furnace and a casting furnace. Five samples were directionally solidified upwards at a constant temperature gradient (G = 5.5 K/mm) under different growth rates (V = 8.3–165 μm/s) in a Bridgman-type directional solidification furnace. The primary dendrite arm spacing, λ1, secondary dendrite arm spacing, λ2, and microhardness, HV, of the samples were measured. The effects of V on λ1, λ2 and HV properties of the Al-Zn-Mg alloy were studied by microstructure analysis and mechanical characterization. Microstructure characterization of the alloys was carried out using optical microscopy, scanning electron microscopy, wavelength-dispersive X-ray fluorescence spectrometry, and energy dispersive X-ray spectroscopy. From the experimental results, it is found that the λ1, λ2 values decrease, but HV values increase with the increase in V, and HV values decrease with the increase in λ1 and λ2. Dependencies of dendritic spacing and microhardness on the growth rate were determined using linear regression analysis. The growth rate, microstructure, and Hall–Petch-type relationships obtained in this work have been compared with the results of previous studies. © The Minerals, Metals & Materials Society and ASM International 2016 |
