Hot compression deformation behavior and a modified physically-based constitutive model of Cu-6 %Ag alloy

Abstract In order to reveal the flow characteristics of Cu-6 %Ag alloy on the condition of hot deformation, the isothermal compression experiments are carried out at the temperatures of 973–1123 K under strain rates of 0.01–10 $ s^{−1} $. The effects of deformation condition on the hot compression d...

520			\|a Abstract In order to reveal the flow characteristics of Cu-6 %Ag alloy on the condition of hot deformation, the isothermal compression experiments are carried out at the temperatures of 973–1123 K under strain rates of 0.01–10 $ s^{−1} $. The effects of deformation condition on the hot compression deformation behavior are investigated. The low instability strain (ɛi) behavior at high strain rate (10 $ s^{−1} $) is discussed in this paper. According to the experiment results and analyses, the deformation twinning and inhomogeneous grains are thought to be the possible reasons for low strain cracking. Then, a modified physically based constitutive model is established. The strain for maximum softening rate %$ (\varepsilon_{ } ) %$ is quoted in the constitutive equation which is proved that there is a nearly linear relationship between %$ { \ln }\varepsilon_{ } %$ and %$ { \ln }Z %$. What’s more, the correlation coefficient (R) and the average absolute relative error (AARE) are used to evaluate the accuracy of the established constitutive model. The values of R and AARE are 0.99612 and 3.47 %, respectively, which show that the modified constitutive model can exactly reveal the flow stress of Cu-6 %Ag alloy.

The effects of deformation condition on the hot compression deformation behavior are investigated. The low instability strain (ɛi) behavior at high strain rate (10 $ s^{−1} $) is discussed in this paper. According to the experiment results and analyses, the deformation twinning and inhomogeneous grains are thought to be the possible reasons for low strain cracking. Then, a modified physically based constitutive model is established. The strain for maximum softening rate %$ (\varepsilon_{ } ) %$ is quoted in the constitutive equation which is proved that there is a nearly linear relationship between %$ { \ln }\varepsilon_{ } %$ and %$ { \ln }Z %$. What’s more, the correlation coefficient (R) and the average absolute relative error (AARE) are used to evaluate the accuracy of the established constitutive model. The values of R and AARE are 0.99612 and 3.47 %, respectively, which show that the modified constitutive model can exactly reveal the flow stress of Cu-6 %Ag alloy.

The effects of deformation condition on the hot compression deformation behavior are investigated. The low instability strain (ɛi) behavior at high strain rate (10 $ s^{−1} $) is discussed in this paper. According to the experiment results and analyses, the deformation twinning and inhomogeneous grains are thought to be the possible reasons for low strain cracking. Then, a modified physically based constitutive model is established. The strain for maximum softening rate %$ (\varepsilon_{ } ) %$ is quoted in the constitutive equation which is proved that there is a nearly linear relationship between %$ { \ln }\varepsilon_{ } %$ and %$ { \ln }Z %$. What’s more, the correlation coefficient (R) and the average absolute relative error (AARE) are used to evaluate the accuracy of the established constitutive model. The values of R and AARE are 0.99612 and 3.47 %, respectively, which show that the modified constitutive model can exactly reveal the flow stress of Cu-6 %Ag alloy.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Flow Stress</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Constitutive Model</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Dynamic Recrystallization</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">True Stress</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Dynamic Recovery</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Menghan</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Liu, Xiao</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Fenglin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Applied physics</subfield><subfield code="d">Berlin : Springer, 1973</subfield><subfield code="g">122(2016), 4 vom: 14.

title_auth	Hot compression deformation behavior and a modified physically-based constitutive model of Cu-6 %Ag alloy
abstract	Abstract In order to reveal the flow characteristics of Cu-6 %Ag alloy on the condition of hot deformation, the isothermal compression experiments are carried out at the temperatures of 973–1123 K under strain rates of 0.01–10 $ s^{−1} $. The effects of deformation condition on the hot compression deformation behavior are investigated. The low instability strain (ɛi) behavior at high strain rate (10 $ s^{−1} $) is discussed in this paper. According to the experiment results and analyses, the deformation twinning and inhomogeneous grains are thought to be the possible reasons for low strain cracking. Then, a modified physically based constitutive model is established. The strain for maximum softening rate %$ (\varepsilon_{ } ) %$ is quoted in the constitutive equation which is proved that there is a nearly linear relationship between %$ { \ln }\varepsilon_{ } %$ and %$ { \ln }Z %$. What’s more, the correlation coefficient (R) and the average absolute relative error (AARE) are used to evaluate the accuracy of the established constitutive model. The values of R and AARE are 0.99612 and 3.47 %, respectively, which show that the modified constitutive model can exactly reveal the flow stress of Cu-6 %Ag alloy. © Springer-Verlag Berlin Heidelberg 2016
