“…Some scholars have effectively improved the overall mechanical properties of the material by adding hard ceramic particles to the titanium alloy powder [9] . Compared with TiC [10] , SiC [11] , ZrO2 [12] and other ceramic particles that are directly used as reinforcing phases, adding TiB2 particles to the titanium alloy matrix powder to synthesize short-fiber-like TiB whiskers in situ [13] , which have good interfacial bond strength with the matrix material. Additionally, due to the hardness of TiB and its role as a nucleating agent during material solidification, it can significantly improve the microhardness and wear resistance of the matrix [14][15] .…”

In this paper, Ti6Al4V+3 wt.% TiB2 composite powder was used as a raw material to synthesize TiB whiskers in situ and prepare composites reinforced with TiB/Ti6Al4V whiskers by selective laser melting (SLM). The effects of process parameters on the properties of TiB/Ti6Al4V samples were systematically studied. The evolution of the microstructure, including the formation and regulation of whiskers, and the effects on mechanical properties were discussed. The results showed that during the SLM process, adjusting the energy density effectively inhibited cracking in the TiB/Ti6Al4V samples. The TiB2 particles acted as nucleation centers to significantly refine the grains during processing and reacted with elemental Ti to form a needle-like TiB network at the grain boundaries, which strengthened the whiskers. Additionally, TiB played a role in dispersion strengthening. Compared with Ti6Al4V, the microhardness of TiB/Ti6Al4V was 430.6?11.45 HV, an increase of 27.9%, and the wear volume of the sample was 0.85?10-3 mm3, a decrease of 62.64%.

“…Any material and its products are working under the coupling effect of multi-physical fields, such as mechanical, thermal, electrical, magnetic fields and etc [1][2][3][4]. For semiconductors, the electrical-mechanical coupling effect is of particular importance since they are the main materials in micro-and nano-electronic devices [5][6][7][8].…”

In this research, the electrical-mechanical coupling performance of gallium arsenide (GaAs) crystalline has been investigated by carrying out the in situ electrical measurement experiments which enabled us to record precisely both the mechanical behavior of the nanodeformed GaAs and the accompanying electrical response during nanoindentation. An effective and precise In situ electrical measurement system has been set up by introducing a conductive diamond indenter and both traditional and cyclic nanoindentation experiments have been performed. The experimental results showed that the application of indentation force caused a significant increase in the current flow due to the pressure-induced metallic phase transition of GaAs, and the magnitude of current flow was increased with increasing either the applied force or voltage. Furthermore, the current flow showed symmetric changes with the indentation loading and unloading, indicating a fully reversible metallic phase transformation of GaAs in indentation. On the other hand, the externally applied voltage (electrical field) was observed to barely affect the indentation force-depth curve (mechanical performance) of GaAs in respect of Young's modulus and hardness.
