Journal ArticleDOI
Constitutive equations for elevated temperature flow stress of Ti–6Al–4V alloy considering the effect of strain
TL;DR: In this article, the effects of temperature and strain rate on deformation behaviors were represented by Zener-Holloman parameter in an exponent-type equation, and the influence of strain was incorporated in constitutive analysis by considering the effect of strain on material constants.
Journal ArticleDOI
Flow behavior modeling of the 7050 aluminum alloy at elevated temperatures considering the compensation of strain
TL;DR: In this article, a constitutive equation of 7050 aluminum alloy considering the compensation of the strain was proposed, and the correlation coefficient and the average absolute relative error (AARE) were introduced to verify the validity of the constitutive equations.
Journal ArticleDOI
A Modified Johnson-Cook Constitutive Equation to Predict Hot Deformation Behavior of Ti-6Al-4V Alloy
TL;DR: In this paper, a modified Johnson-Cook constitutive equation of Ti-6Al-4V alloy is proposed based on hot compression tests performed in the temperature range of 1073-1323 K and strain rate 0.001-1−s−1.
Journal ArticleDOI
Comparative investigation on the modified Zerilli–Armstrong model and Arrhenius-type model to predict the elevated-temperature flow behaviour of 7050 aluminium alloy
TL;DR: In this article, the suitability levels of these two models were evaluated by comparing both the correlation coefficient R and the average absolute relative error (AARE), and the number of material constants involved in the two models was also compared.
Journal ArticleDOI
Investigation of mechanical behavior of quenched Ti–6Al–4V alloy by microindentation
TL;DR: In this article, the micro mechanical behavior of quenched Ti-6Al-4V alloy was investigated in a wide range of maximum loads: 200, 300, 500, 700, 1000, 1500, 2000, 3000, 3500 and 4900mN, and loading speeds: 10, 40 and 103mN/s.
