“…Simultaneously, the mass volatilization rates of Ti in the experiment (N m,E (Ti)) were calculated via Equation (10). Based on the Hertz-Knudsen-Langmuir equation (Equation ( 8)), the average temperatures of the molten pool surface at different melting powers were calculated [43]. They were 2250 K, 2306 K, 2322 K and 2345 K at melting powers of 10.5 kW, 12.0 kW, 13.5 kW and 15.0 kW, respectively.…”

The effects of electron beam melting parameters on the volatilization behavior of elements and the microstructures of ingots were investigated on a β-type Ti-Mo binary alloy. The microstructures of the ingots consisted of large and columnar grains at their bottom and top sections, respectively, and they were similar at different melting powers, from 10.5 kW to 15.0 kW, and the melting time ranging from 10 min to 40 min, without apparent metallurgical defects. Mass losses of ingots exhibited an increasing tendency, with increases of both melting power and melting time. Combined with a theoretical calculation and X-ray fluorescence results, Ti was identified as the main volatilization element due to its much higher vapor pressure than that of the Mo element. The considerable compensation method of the volatile Ti element was established in terms of theoretical and experimental results, which could provide a guidance for fabricating composition-controllable Ti-Mo binary alloys via electron beam melting technology.

“…It can be seen that both of the fibers gradually start to decompose substantially at ~180 °C, indicating that the addition of LM does not affect the thermal stability of the original composite fiber. It is worth noting that the breakdown rate of TAWL fibers is often slower than that of TA fibers, probably due to the inherent high thermal conductivity [51,52] and low saturation vapor pressure of the eutectic gallium indium (EGaIn) LM, [53] even at ~1000 °C. Also, the adhesive on the surface of TAW fibers acts as a heat conduction layer to a certain extent, transferring a certain amount of heat away, thus delaying the overall decomposition rate of the fiber.…”

Realizing stretchable conductive fibers with a trade‐off between stretchability and conductivity is important for wearables. Fibrous triboelectric nanogenerators (FTENGs) represent a promising device for wearable power sources and self‐powered sensors. However, the relationship between conductivity and triboelectric outputs of FTENG remains unfathomed. Herein, a simple strategy for fabricating stretchable conductive fibers with binary rigid‐soft conductive components and dynamic compensation conductive capability is reported. Wet‐spun thermoplastic polyurethane (TPU)/silver flakes (AgFKs) (TA) composite fiber is fabricated and coated by a water‐borne polyurethane (WPU) thin layer, bridging the subsequent liquid metal (LM) coating to obtain TPU/AgFKs/WPU/LM (TAWL) fibers. The TAWL fiber shows outstanding elongation (~600% strain), electrical conductivity of ~2 Ω cm−1 (~3125 S cm−1), and reversible resistance response within 70% tensile strain. Encapsulated by polydimethylsiloxane (PDMS), the TAWL fiber is demonstrated as single electrode FTENG with the maximum output voltage, current, and transferred charge of 7.5 V, 167 nA, and 3.2 nC, respectively. The FTENG shows 150% stretchability without output dropping, demonstrating the superiority of TAWL fibers to sustain large deformation and conductivity degradation but maintain stable triboelectric outputs. As self‐powered sensors, the FTENG can detect joint bending such as for fingers, elbows, and knees, as well as for pressure and location identification.
