Summary: This paper investigates the scheme of using an integrated infrared thermometer to measure sea surface temperature. By considering the emissivity characteristics of the sea surface and eliminating the influence of sky background radiation, accurate sea surface temperature can be obtained. This scheme helps reduce the size and weight of measuring instruments, decrease costs, and promote the large-scale application of sea surface temperature monitoring.

Summary: During the machining process, substantial thermal loads are generated, leading to issues such as accelerated tool wear, dimensional inaccuracies, and thermally induced defects. Temperature, an important machining response, is difficult to monitor in high-speed machining applications. This article reviews the thermocouple and infrared radiation temperature measurement methods used by researchers in turning, drilling, and milling operations, and evaluates their merits and limitations.

Summary: This study investigates the influence of dry grain boundaries, isolated solid-melt interfaces, and triple junction energies on premelting and solid-melt transformations at the nanoscale using a Ginzburg-Landau phase field approach. By modeling the variation of transformation temperatures with width ratio, the research shows bistable regions and hysteresis effects in premelting. The study also explores the role of triple junctions in inducing premelt pockets at lower temperatures than grain boundaries, leading to complete melting of the sample.

Summary: In this study, a ternary W alloy containing 5 wt% V and 5 wt% Ta was fabricated using mechanical alloying and spark plasma sintering. The alloy exhibited a single-phase body centered cubic structure with (V, Ta)-enriched fine grains and W-enriched grains. It showed an ultrafine grain size and higher relative density, microhardness, and strength compared to pure W. The strengthening mechanisms were analyzed, and it was found that grain refinement, densification, and solid solution played different roles in strengthening. The alloy demonstrated good irradiation resistance, which was attributed to its ultrafine grains and higher compressive and tensile strength. The potential application of the W-5 wt%V-5 wt%Ta alloy as a plasma-facing material was suggested.

Summary: This paper designs a non-contact infrared temperature measuring device to measure the rubber temperature in the mixing process. The experimental results show that the measurements from the infrared temperature measuring device are more accurate compared to the thermocouple temperature measuring device. The infrared temperature measuring device is therefore more suitable for measuring the dynamic temperature of rubber in the mixer.

Summary: Laser light absorption is a fundamental effect in laser material processing, and plays a crucial role in calculating process efficiency and predicting material impact. However, measuring absorption can be challenging, especially at high temperatures where limited experimental data is available. To improve theoretical models, this study proposes a radiometric measurement method using a heating laser to create a metal melt pool, while measuring temperature and reflection using a second laser beam. Measurements confirmed general tendencies but showed scattered absorption values at increasing temperatures. An increase in absorption between melting and boiling temperatures (35% to 38%) suggests the need to consider both interband and intraband absorption mechanisms in this regime. At higher temperatures, intraband absorption becomes the dominant mechanism, reaching absorption values above 45%.

Summary: The hydrogen sorption properties of Ti4M2Oy compounds were studied to evaluate their potential as room-temperature hydrogen storage materials. The results indicated that Ti4Ni2O was a better candidate for room-temperature hydrogen storage. Partial substitutions of Fe, Co, and Cu for Ni did not improve the usable capacity, but they allowed for precise control of the equilibrium hydrogen pressure through composition changes.

Summary: The effect of equal-channel angular pressing (ECAP) on the microstructure and strength of Zn-4Ag-1Cu zinc alloy has been investigated. The results show that the ECAP samples have equiaxed grains and uniformly distributed particles, with a size range of 1.5μm to 4μm for grains and 200nm to 1μm for particles. The ECAP samples exhibit high strength of 348 MPa and good ductility, demonstrating their potential for producing medical stents.

Summary: Novel refractory high entropy alloys (RHEAs) of the Ti-Zr-V-Mo system with a single bcc solid solution structure were predicted and confirmed for the first time using molecular dynamics, resulting in twelve new compositions with a single bcc structure. Molecular dynamic simulations were conducted to study the tensile deformation behavior and mechanism of the equiatomic RHEA TiZrVMo, revealing dislocation toughening, stacking fault formation, as well as reversible bcc to fcc and hcp phase transformations during plastic deformation. This work provides important theoretical insights for composition design and ductility understanding of RHEAs in practical applications.
