Special Issue Information

Dear Colleagues,

This Special Issue on ‘Recent Insights into the Mechanical Properties of Metallic Alloys’ will publish critical studies conducted by scientists working in the field of metallurgy and materials science all over the world.

A focus of materials scientists has often been the study of the mechanical properties of metallic alloys, due to their critical role in a wide variety of technological applications. Recent developments in analytical techniques and mathematical modelling allowed researchers to obtain deeper insights into the primary mechanisms that determine these properties. This has led to significant progress in the development and optimization of alloys.

In particular, these tools have promoted the design of new alloys with tailored properties, such as high-entropy alloys and shape-memory alloys.

Recent studies have also focused on the impact of additive manufacturing  techniques, such as selective laser melting and electron beam melting, on the mechanical performances of several alloys. In fact, additive manufacturing allows researchers to realize complex geometries and tailored microstructures: this produces unique mechanical properties that are not achievable through conventional manufacturing techniques.

Metal–metal functionally graded materials also offer significant challenges in the industrial field as they may guarantee customised gradients in microstructures and properties, and open up new opportunities for innovation.

In the final analysis, novel insights into the mechanical properties of metallic alloys, supported by advances in experimental techniques and computational methods, are changing our knowledge in materials science. These developments aim at enhancing the performance of alloys in existing applications as well as finding new applications in emerging and promising technological fields.

This Special Issue welcomes contributions that include original research manuscripts, reviews, and case studies. We look forward to receiving your contributions.

In this paper, a pulsed laser is applied to realize these complicated thermal cycles experimentally, coupling with the constant mechanical loading with the self-designed sample holder. A numerical simulation model is proposed to calculate the temperature and stress under thermal cycles of variable amplitude coupled with mechanical loading. The findings indicate a strong correlation between the measured temperature curve and the simulated results under various loading parameters. It is observed that the calculated depth of thermal–structural interaction for low-cycle conditions exceeds that of high-cycle conditions. In addition, the mechanism of crack evolution under thermal cycles of variable amplitude coupled with mechanical loading is discussed. This paper offers extensive experimental and numerical perspectives on the damage process occurring under thermal cycles of varying amplitudes combined with mechanical loading, highlighting its substantial engineering importance for conducting failure analyses and optimizing the design of hot-end components.

This study investigates the role of coalesced bainite in enhancing the hydrogen embrittlement resistance of tempered martensitic steels. By analyzing the microstructural characteristics and mechanical properties under varying cooling rates, it was found that the presence of coalesced bainite significantly impedes hydrogen accumulation at prior austenite grain boundaries. This leads to a transition in the fracture mode from intergranular to transgranular, thereby improving the overall resistance to hydrogen embrittlement in steels. Slow strain rate tests (SSRTs) on both smooth and notched specimens further confirmed that steels cooled at lower rates, which form a higher fraction of coalesced bainite, exhibiting superior hydrogen embrittlement resistance. These findings suggest that optimizing the cooling process to promote coalesced bainite formation could be a valuable strategy for enhancing the performance of tempered martensitic steels in hydrogen-rich environments.

In this study, the effect of the cold plastic deformation of a Bridgman anvil at room temperature on the hardness and wear resistance of X160CrMoV12 steel was investigated by utilizing the hardness test, X-ray diffraction (XRD), abrasive emery wear (AEMW) test, optical examination, and scanning electron microscopy (SEM). Three batches of samples were prepared for the experiment: I—as-hardened, II—after hardening with subsequent tempering at 600 °C for 1.5 h, and III—after hardening with subsequent plastic deformation. The hardening of the samples was performed at three temperatures: 1100 °C, 1150 °C, and 1200 °C. The highest content of retained austenite, as much as 69.02%, was observed during hardening at 1200 °C, while 17.36% and 38.14% were formed at lower temperatures, respectively. After tempering (Batch II), the content of residual austenite decreased proportionally by a factor of about seven for each hardening temperature. The effect of plastic deformation (Batch III) is observed, analyzing the hardness of the samples from the surface to the depth, reaching an average hardened depth of 0.08 mm. To evaluate the wear resistance, the surfaces of the three test batches were subjected to an abrasive emery wear test under a 5 N load. Hardened and plastically deformed samples showed higher wear resistance than hardened and tempered samples. The results confirmed that the optimal hardening temperature to achieve the maximum wear resistance of this steel is 1100 °C. Full article
