“…In the whole simulation process, the total number of steps is set to 100 and saved every ten steps. The numerical simulation method adopts the conjugate gradient iterative method, and the iterative method adopts the direct iteration method (Li et al, 2012;Sun et al, 2005). 3 Numerical simulation and experimental results…”

The finite element numerical simulation of hot compression deformation process of B93 aluminium alloy was carried out by DEFORM-3D software. Besides, the microstructure characteristics of deformed specimens in different regions and the relationship between non-uniform strain and dynamic recrystallisation during deformation were analysed by experimental study. The results show that the hot compression process of B93 aluminium alloy obviously exhibits a nonuniform characteristic of deformation, the region with the largest equivalent strain is the most prone to deformation. Also, in the largest equivalent strain zone, dynamic recrystallisation reacts the most complete, and the grain size reaches the minimum value. Nonuniform deformation show a rising tendency with the increase of strain rate and deformation temperature, and the influence of strain rate on nonuniform deformation is slightly greater than that of deformation temperature. The most suitable hot working process for the alloy is 410~430°C/0.001~0.01s -1 .

“…70,80 At lower drawing deformation, the steels always show a decreased grain size with finer interlamellar spacings in the pearlite, and the cementite becomes fragmented, especially in warm deformation. 50,69,81 The change in the fraction of cementite as a function of drawing strain is shown in Fig. 33.…”

A comprehensive review of recent literature on high strength, fine grained steels has been conducted. While relevant technologies in alloy design, processing and heat treating are included in the present review, the emphasis has been on high carbon steel wire processing technology that can be achieved with 'conventional' wire rolling and drawing processes. The thermomechanical processing of a pearlitic microstructure, followed by cold drawing, is recommended as the process of choice to efficiently produce an ultrafine grained ferrite-cementite microstructure for ultrahigh strength, ultrahigh carbon steel wires.

“…Cross wedge rolling is originally used in the production of step shaft parts, which can compress and extend different positions of the rolled part in a continuous process [4]. Moreover, the recrystallization, spheroidization and other ne-crystal behavior can be triggered due to the severe plastic deformation [5].…”

This paper proposed to use cross wedge rolling (CWR) to manufacture sintered TC4 (S-TC4) titanium alloy blade preform prepared by powder metallurgy technology. The hot uniaxial compression tests, CWR experiments and numerical simulation were carried out to investigate the in uence of forming parameters on microstructure evolution. The results showed that the pattern of stress-strain curve is typical featured of work hardening and dynamic softening, and the Arrhenius equation was determined to describe the high temperature ow behavior of the studied S-TC4 alloy. In regard to microstructure evolution, the volume fraction of alpha phase increases and then decreases radially from inside to outside, and the lamellar alpha phase was equiaxialized by to the shear and torsion stress. And increasing the initial forming temperature T was not conducive to the preservation of the alpha phase, and both the volume fraction of alpha phase f α and average thickness of lamellar alpha phase l α are negatively correlated with the rolling speed n and area reduction . Moreover, the maximum initial forming temperature, rolling speed and area reduction are 940℃, 10r/min and 60%, respectively, in order to achieve the best match between strong plasticity and thermal.
