“…Alloying hot-working die steel is an important way to improve its service life. The performance of hot-working die steel can be influenced to varying degrees by different alloying elements and their respective content levels, resulting in either positive or negative effects [ 27 , 59 , 60 , 61 , 62 , 63 , 64 , 65 ]. Table 2 lists the appropriate content ranges of some alloying elements and their functions in hot-working die steels.…”

“…Electroslag remelting (ESR) was developed rapidly in the 1960s as a secondary refining technology. Such a method can effectively control the inclusions, such as their size, quantity, shape, and distribution, thereby improving the solidification microstructure [ 64 , 81 , 82 , 83 , 84 , 85 ]. During the ESR process, deoxidation plays a crucial role as it effectively reduces the number of inclusions and hinders the formation of new ones.…”

In the general environment of lightweight automobiles, the integrated die-casting technology proposed by Tesla has become the general mode to better achieve weight reduction in automobiles. The die-casting mold required by integrated die-casting technology has the characteristics of large scale and complexity. Hence, higher requirements are put forward for the comprehensive performance of the die steel. Despite the stagnation in the progress of conventional strengthening methods, enhancing the performance of die steel has become increasingly challenging. Indeed, it necessitates exploring novel die steel and optimizing heat treatment and reinforcement technologies. This article summarizes and analyzes the development status of die steel and corresponding heat treatment and microstructure manipulation as well as strengthening methods and elaborates on an excellent nano-strengthening technology. Furthermore, this review will aid researchers in establishing a comprehensive understanding of the development status of die steel and the processes utilized for its strengthening. It will also assist them in developing die steel with improved comprehensive performance to meet the high demand for mold steel in the integrated die-casting technology of the new era.

“…Thus far, the sound absorption properties of numerous types of lattice structures have been investigated. This includes lattice structures consisting of solely trusses, [ 9–11 ] solely plates, [ 11 ] trusses and plates, [ 11,12 ] tubes, [ 13,14 ] tubes and plates, [ 15–17 ] smooth skeletal structures, [ 18–20 ] triply periodic minimal surface, [ 21,22 ] and bioinspired features. [ 23 ] Beyond the unit cell level, heterogeneities such as heterogeneously‐structured unit cells placed in parallel, [ 12,23,24 ] functionally graded arrangements, [ 25–28 ] and additional acoustic meta‐features [ 9 ] have also been proposed.…”

The reduction of noises, achieved through absorption, is of paramount importance to the well‐being of both humans and machines. Lattice structures, defined as architectured porous solids arranged in repeating patterns, are emerging as advanced sound‐absorbing materials. Their immense design freedom allows for customizable pore morphology and interconnectivity, enabling the design of specific absorption properties. Thus far, the sound absorption performance of various types of lattice structures are studied and they demonstrated favorable properties compared to conventional materials. Herein, this review gives a thorough overview on the current research status, and characterizations for lattice structures in terms of acoustics is proposed. Till date, there are four main sound absorption mechanisms associated with lattice structures. Despite their complexity, lattice structures can be accurately modelled using acoustical impedance models that focus on critical acoustical geometries. Four defining features: morphology, relative density, cell size, and number of cells, have significant influences on the acoustical geometries and hence sound wave dissipation within the lattice. Drawing upon their structural‐property relationships, a classification of lattice structures into three distinct types in terms of acoustics is proposed. It is proposed that future attentions can be placed on new design concepts, advanced materials selections, and multifunctionalities.
