Effects of temperature on the tribological behavior of Al0.25CoCrFeNi high-entropy alloy

• Ti-44.5Al-3.8Nb-1Mo-0.2B alloy sheets with different initial microstructures were fabricated by the multi-pass small deformation rolling technique. • The as-rolled sheet deriving from fully lamellar structure possessed a smaller grain size than that from nearly lamellar structure. • Larger deformation was needed for fully lamellar structure to obtain complete recrystallization. Ti-44.5Al-3.8Nb-1Mo-0.2B alloy (TNM) sheets were prepared by hot rolling, and the effect of the initial microstructure on the process was discussed in this work. The as-received TNM alloy billets with nearly and fully lamellar structures were prepared by forging and casting processes (named M1 and M2), respectively. For the as-rolled sheets from M1, the fraction of recrystallization increased gradually with the decrease of reduction per pass based on GOS analysis. Compared with M1, M2 required a larger deformation to achieve complete recrystallization. Meanwhile, the as-rolled sheets from M2 possessed a smaller grain size than that from M1. In addition, the γ-DRX behavior during the multi-pass hot rolling was discussed, and the DDRX was found to play the dominant role in this process. The phase transformation of β/β 0 → α occurred in the 1200 °C rolling process. It was presumed that this transformation was promoted by increasing the rolling temperature, therefore, the volume fraction of the β 0 phase decreased. The α 2 lath decomposed gradually with the increasing of rolling temperature from 1200 °C to 1250 °C, simultaneously, the combination of the adjacent γ laths resulted in the coarsening of γ lath. 

Microstructure evolution and recrystallization of Ti-44.5Al-3.8Nb-1Mo-0.2B alloy with different initial microstructure during hot pack rolling

Ti–43Al–4Nb–1Mo-0.2B (at.%) (TNM) alloy sheets were fabricated, and the corresponding microstructure developed from lamellar to duplex structure with the rolling reduction increased from 50% to 72.5%. Interestingly, novel Z-type lamellar structure developed at 67.5% deformation strain and the formation process was discussed by calculating of the Schmidt factor. Moreover, α 2 +γ→β 0 phase transformation occurred at the kink band boundaries. Subsequently, as the reduction increased to 72.5%, the coarse β o phase decomposed and transformed to α 2 +γ phases due to the distortion energy stored after multi-pass rolling. Finally, the room-temperature tensile properties of the TNM sheets were tested. With the comparison of the as-forged alloy, the strength and ductility increased significantly by hot rolling, and the ultimate tensile strength reached 880 MPa with a deformation of 60%. The relationship between the rolling process, microstructure evolution, and corresponding properties was established. 

The microstructure evolution and tensile properties of Ti–43Al–4Nb–1Mo-0.2B alloy during hot rolling

Abstract. High-entropy alloy is a promising structural material for high-temperature service applications due to the designable superior properties. Superplasticity, normally achieved at relatively high temperature and low strain rate, enables difficult to formation materials to manufacture complex-shaped parts. This paper presents a feasibility experimental study on the deformation and microstructure of CoFeMnNi high-entropy alloy under hot deformation conditions with low strain rate. A series of hot uniaxial tests were conducted at the temperature range between 800-1000℃ with typical strain rates of 10-4 and 10-5/s to determine the stress-strain behaviours. Additionally, to understand the deformation mechanism, microstructure evolution after deformation was characterized. Finally, a mechanism based constitutive model of high-entropy alloy was developed, which facilities the process optimization by finite element simulations.
