“…Except for the tensile or compressive properties, data of other mechanical properties, such as wear resistance, impact toughness, fatigue properties, or creep resistance, of Fe-rich HEAs is very limited. Based on the cost-effective age-hardenable Fe 45 Ni 25 Cr 25 Mo 5 HEA, Yu and co-workers developed an intermetallics and carbides reinforced Fe 40.5 Ni 22.5 Cr 22.5 Mo 4.5 Ti 5 C 5 HEA with superior wear resistance [46]. As shown in Figure 8a-d, the as-cast FeNiCrMoTiC alloy consists of an FCC solid solution matrix with randomly-distributed carbides and FCC/intermetallics eutectic structures.…”

High-entropy alloys (HEAs) have attracted increased attention due to their extraordinary properties. However, the multicomponent characteristic of equiatomic HEAs inevitably leads to high material costs, which thus limits their widespread industrial applications. Although HEAs are claimed to be suitable for applications in extreme environment due to their comprehensive properties, the actual properties of HEAs dramatically vary with compositions and processes. Therefore, the development of cost-effective HEAs with comprehensive properties is indispensable for industrial uses. Till now, although comprehensive review papers on HEAs are available, few works focused on the cost-effectiveness of HEAs, particularly Fe-rich HEAs recently developed. This review thus aims to fill this gap by reviewing the current research progress in Fe-rich HEAs with a focus on the composition design, microstructure, and properties, including mechanical properties, and resistances for oxidation, wear, and corrosion. The challenges for applying cost-effective Fe-rich HEAs into industries are also arising as future research topics.

Fillers play a decisive role in the mechanical properties of polymer composites. In this paper, different particle sizes of nitroguanidine were obtained to regulate the internal filler structure of triple‐base propellants (TBP) to improve their mechanical response in different environments. A series of morphological and structural characterizations on nitroguanidine (NQ) particles were conducted using techniques. The results indicated that the obtained NQ particles maintained a high level of crystalline quality while preserving their molecular integrity. The mechanical properties of TBP were systematically evaluated under various loading conditions, including cryogenic tensile, compressive, and impact loads, as well as dynamic thermomechanical effects. Additionally, three‐point bending simulations were employed to elucidate the mechanical responses and damage mechanisms. Under axial tensile and compressive loads, reducing the particle size of NQ significantly enhanced the tensile and compressive strength. The maximum tensile strength and compressive strength can reach 344.62 MPa and 104.79 MPa. Moreover, the compressive failure mode transitioned from cracking to axial shrinkage. Conversely, when subjected to radial bending loads, TBP exhibited contrasting behavior, including a decrease in the glass transition temperature from 84.73°C to 76.93°C and a non‐monotonic trend in impact strength (initially increasing from 4.96 to 8.85 kJ/m2 and then decreasing to 2.27 kJ/m2). This study provides valuable insights into the mechanical performance of TBP, supporting the development of high‐energy, high‐strength TBP formulations.Highlights SEM analysis confirms the pronounced orientation effect of rod‐like NQ. The orientation and particle size of NQ decide TBP's radial impact resistance. Submicron NQ enhances the compression resistance property of TBP. Submicron NQ brings about a shift in the microscopic damage morphology of TBP.
