Special Issue Information

Dear Colleagues,

In today's material science and engineering, the demand for high-performance materials is increasing. Pure metals, alloys, and rare earth metals and alloys play a key role in many fields, such as electronics, optics, and semiconductors. With the continuous progress of technology, the performance requirements of metal materials are getting higher and higher. It is of great scientific significance and practical application value to study the plastic deformation process of metal blanks based on numerical simulation and experimental research.

This Special Issue aims to explore the plastic deformation process of metal billets through numerical simulation technology. Specifically, we focus on understanding the microstructure evolution during plastic deformation processes such as rolling and provide innovative practical guidance for the plastic deformation mechanism of large-sized billets. We aim to optimize the deformation process, improve the quality and performance of materials, and predict the deformation behavior and failure mode of materials to meet the needs of specific application fields.

In this Special Issue, we welcome original research articles and reviews. Research areas may include (but are not limited to) the following:

  1. Finite element studies on plastic deformation of metals.
  2. Microstructure evolution of metal billets during plastic deformation.
  3. Explore a new process for obtaining fine grains of metal.
  4. Study the stress and strain distribution during the deformation process of metals.
  5. The application of metal/plastic deformation across specific industries.

Related fields can also involve (but are not limited to) rare earth aluminum alloys, rare earth magnesium alloys, rare earth titanium alloys, rare earth master alloys, rare earth steel materials, and rare earth transition metal-based alloys.

Based on the results of current research and experiments, clock 135° hot rolling has been widely considered to be the preferred method in target rolling. However, it has been found that the process parameters are of vital importance during the rolling. Therefore, this work focuses mainly on the investigation of the effects of the roll speed ratio and offset distance on the microstructure evolution of a pure aluminum (Al) target under clock 135° collaborative hot rolling. Taking the ultra-thick pure Al metal circular billet as a research object, firstly, the evolutionary behavior of the effective strain (ES) and grain refinement for a rolled piece under the clock counterclockwise 135° synchronous and asynchronous (the speed ratios between rollers are set to be 1:1.05, 1:1.1, 1:1.2, respectively) rolling modes has been comparatively studied based on numerical simulation by DEFORM-3D software. It has been shown that a large ES value of 5.835 mm/mm is obtained in the lower surface layer by counterclockwise 135° asynchronous rolling with a roll–speed ratio of 1:1.2. Meanwhile, the average grain size below 80 µm accounts for ~61.8% of the total grains. These results demonstrate that the clock counterclockwise 135° asynchronous rolling method with a roll speed ratio of 1:1.2 should be an ideal strategy in obtaining finer grains. Unfortunately, nevertheless, the maximum degree of the bad plate shape is generated after forging by clock asynchronous rolling with a speed ratio of 1:1.2. As a consequence, clock counterclockwise 135° snake rolling with a 30 mm offset distance was proposed on the basis of a rolling speed ratio of 1:1.2, which perfectly corrected the warping plate shape caused by clock asynchronous rolling. What is more important, the minimum damage value of 1.60 was achieved accordingly. Meanwhile, the ES value increased in the core of the plate for the clock counterclockwise 135° snake rolling with all of the four offset distances compared to clock synchronous rolling. This study should be significantly conducive to guidance on setting process parameters in the industrial production of hot rolling metal or alloy targets. Full article
