“…The energy spectrum analysis results of the 35CrMoV steel matrix and corrosion products after corrosion are displayed in Figure 15. It can be seen from Figure 15 that the surface of the matrix after heat treatment mainly contains Fe, and some studies have shown that its structure is tempered sorbite [49,50]. In summary, the corrosion products on the surface after corrosion are mainly FeOOH.…”

Hot deformation experiments of as-cast 35CrMoV steel, with strain rates of 0.01 s−1 and 10 s−1, deformation temperatures of 850, 950, and 1050 °C, and an extreme deformation reaching 50%, were carried out using a Gleeble-3810 thermal simulator. Electrochemical corrosion experiments were conducted on the deformed specimens. The microstructure was observed by optical microscope (OM), and the corrosion morphology and corrosion products of the specimens were investigated by scanning electron microscopy (SEM), energy disperse spectroscopy (EDS), confocal laser scanning microscopy (CLSM), and X-ray diffraction (XRD) techniques. The results show that the grain size increased gradually with an increase in the deformation temperature at the same strain rate, whereas the corrosion resistance deteriorated. At the same deformation temperature, the grain size becomes smaller as the strain rate increases, which enhances the corrosion resistance. This is mainly attributed to the fine grains, which can form more grain boundaries, increase the grain boundary area, and accelerate the formation of the inner rust layer at the beginning of corrosion. Moreover, fine grains can also refine the rust particles and enhance the bonding strength between the inner rust layer and the matrix. The denseness and stability of the inner rust layer increases as the corrosion process progresses, thereby improving corrosion resistance.

The effect of soaking temperature and duration of cryogenic treatment cycles were investigated for the hot die steel AISI-H13 to improve its wear resistance. The amount of wear, average friction coefficient, and maximum local contact temperature were investigated against the AISI D3 cold work tool steel (hardened and tempered) used as counter-surface for five conditions varying the loading and sliding speed. Sliding parameter has great influence over wear rate when is compared to load effects. The wear detected on the surface analyzed is adhesive wear produced by deformation lips, surface cracks and fractured ridges. To achieve an increase of efficiency, Particle Swarm Optimization is preferred as it showed lower deviation than Bacteria Foraging Optimization in optimized results.

“…Besides this, tool life and wear resistance of the alloys are also significantly enhanced with appropriate cryogenic treatment [30]. In this type of treatment, cooling time, soaking rate and temperature are the critical parameters that alter the properties of alloys [31][32][33]. Researchers have tried to optimize these parameters to achieve the desired material characteristics.…”

Increasing demand for aluminum matrix composites (AMCs) in the manufacturing sector leads to the development of squeeze casted hybrid AMCs bearing superior mechanical attributes. Excessive hardness due to squeeze pressure and the presence of reinforcement particles makes the machining of AMCs challenging and results in excessive tool wear and inadequate surface finish. Wire electric discharge machining (WEDM) process has been preferred over conventional manufacturing processes for the machining of squeeze casted Al2024/Al2O3/W hybrid composite. This study investigates the selection of the most pertinent wire electrode for the precise machining of Al2024/Al2O3/W. Simple zinc-coated (NT) and cryogenic treated (CT) brass wire electrodes have been selected for machining. Scanning electron microscope (SEM) analysis of CT wire shows that cryogenic treatment enhances the soundness and stability by reducing microcavities in its microstructure. To analyze the effects of cryogenic treatment, the machining performance of CT wire has been compared with NT wire. Besides wire type, the influence of key input variables has also been analyzed on the imperative response measures including cutting speed (CS), surface roughness (SR) and kerf width (KW) to make the machining process more effective. Microstructural analysis of NT wire depicts a high concentration of micro-voids, micro-cracks, and deep craters, while the surface of CT has been observed relatively fine after the machining. Comparative analysis of both wire electrodes has declared that CT wire yields 26.96% and 15.10% superior results for CS and SR respectively, and 6.92% deprived results for KW than NT wire.
