Special Issue Information

Dear Colleagues,

It is a great honor and privilege to be involved as Guest Editors of a Special Issue of Materials focusing on advanced manufacturing processes of metal forming.

Metal forming is one of the most common technological methods used in the manufacturing of metal products. It is characterized by the fact that the metal is plastically deformed to give it the desired geometry and physical and chemical properties. The changes in physical and chemical properties mainly consist of changing the structure, mechanical properties, and surface topology of the metal product. There are a number of metal-forming methods for modifying the structure and properties of metals in the desired direction. Due to the increasing demand for high-quality products and the rapid development of science and technology, advanced metal-forming technologies have been successfully developed in recent years. Significant progress can be seen in traditional metal-forming methods, such as die forging, extrusion, punching, drawing, rolling, and pressing, etc. Additionally, unconventional metal-forming methods are being developed, such as SPD incremental forming, CONFORM extrusion, KOBO extrusion, innovative processes for forming flanges in hollow products by moving sleeve extrusion, the rapid tube hydroforming method, drawing using ultrasound, forming on an electromagnetic press, forming on a multi-slide press, plastic microforming processes assisted by low-frequency vibration energy and ultrasonic vibration, and innovative forging rolling processes, etc.

This Special Issue aims to present the latest research and development of advanced manufacturing processes of metal forming. It is our pleasure to invite you to submit a manuscript to this Special Issue. Full research articles, communications, and reviews are welcome for submission.

In this article, the evolution of microstructural characteristics of selectively laser-melted AlSi10Mg alloy subjected to equal channel angular pressing (ECAP) is investigated. The microstructures were analyzed in detail using scanning electron microscopy (SEM), electron backscatter diffraction (EBSD), transmission Kikuchi diffraction (TKD), and transmission electron microscopy (TEM). A heterogeneous ultrafine-grained microstructure was produced after one ECAP pass at 100 °C. This microstructure was composed of Al/Si cells and sub-micrometer grains. The grains were refined by conventional dislocation processes; however, evidence of dynamic recrystallization was also documented. Furthermore, it was revealed that the Al/Si cells contribute significantly to grain refinement. EBSD/TKD investigations showed that cell misorientation increased after ECAP processing, resulting in an increased fraction of grains with very low misorientation angles. Full article

In this paper, the effect of thermomechanical treatment process on the hardening behavior, grain microstructure, precipitated phase, and tensile mechanical properties of the new high-strength and high-ductility Al-10.0Zn-3.0Mg-2.8Cu alloy was studied, and the optimal thermomechanical treatment process was established. The strengthening and toughening mechanisms were revealed, which provided technical and theoretical guidance for the engineering application of this kind of high strength-ductility aluminum alloy. Al-10.0Zn-3.0Mg-2.8Cu alloy cylindrical parts with external longitudinal reinforcement were prepared by a composite extrusion deformation process (reciprocal upsetting + counter-extrusion) with a true strain up to 2.56, and the organizational evolution of the alloys during the extrusion deformation process and the influence of pre-stretching treatments on the subsequent aging precipitation behaviors and mechanical properties were investigated. The results show that firstly, the large plastic deformation promotes the fragmentation of coarse insoluble phases and the occurrence of dynamic recrystallization, which results in the elongation of the grains along the extrusion direction, and the volume fraction of recrystallization reaches 42.4%. Secondly, the kinetic study showed that the decrease in the activation energy of precipitation increased the nucleation sites, which further promoted the diffuse distribution of the second phase in the alloy and a higher number of nucleation sites, while limiting the coarsening of the precipitated phase. When the amount of pre-deformation was increased from 0% to 2%, the size of the matrix precipitated phase decreased from 5.11 μm to 4.1 μm, and when the amount of pre-deformation was increased from 2% to 7%, the coarsening of the matrix precipitated phase took place, and the size of the phase increased from 4.1 μm to 7.24 μm. The finalized heat treatment process for the deformation of the aluminum alloy tailframe was as follows: solution (475 °C/3 h) + 2% pre-stretching + aging (120 °C/24 h), at which the comprehensive performance of the alloy was optimized, with a tensile strength of 634.2 MPa, a yield strength of 571.0 MPa, and an elongation of 15.2%. The alloy was strengthened by both precipitation strengthening and dislocation strengthening. After 2% pre-stretching, the fracture surface starts to be dominated by dense tough nest structure, and most of them are small tough nests, and small and dense tough nests are the main reason for the increase in alloy toughness after 2% pre-stretching deformation.
