ZrW2O8 is a typical isotropic negative thermal expansion material with cubic structure. However, quenching preparation, pressure phase transition and metastable structure influences the practical application. Adopting P to part-substitute W for ZrW2-x P x O8-0.5x has decreased the sintering temperature and avoided the quenching process. When x=0.1, ZrW1.9P0.1O7.95 with a stable cubic structure can be obtained at 1150 ℃. The thermal expansion coefficient is tailored with the P content, and phase transition temperature is lowered. When x=0.5, thermal expansion coefficient attains -13.6×10-6 ℃-1, ZrW1.5P0.5O7.75 exhibits enhance negative thermal expansion property. The difference of electronegativity leads to the decrease of phase transition temperature with the increase of P content. And the different radii of ions lead to new structure of materials when P substitutes more. Results suggest that the P plays the stabilization role in the crystal structure of ZrW2-x P x O8-0.5x .

“…Introducing negative thermal expansion reinforcement to metals provides an effective method for regulating thermal expansion. However, most of the research works focus on Cu [16][17][18] and Al [19,20]. Takenaka et al fabricated different metal matrix composites (Al, Ti, Cu) with Mn 3 AN by spark plasma sintering with various volume fractions and all the composites achieved NZTE [21], which proves the effectiveness of Mn 3 AN.…”

Metal matrix composites with near-zero thermal expansion (NZTE) have gained significant popularity in high-precision industries due to their excellent thermal stability and mechanical properties. The incorporation of Mn3Zn0.8Sn0.2N, which possesses outstanding negative thermal expansion properties, effectively suppressed the thermal expansion of titanium. Highly dense Mn3Zn0.8Sn0.2N/Ti composites were obtained by adjusting the fabrication temperature. Both composites fabricated at 650 °C and 700 °C exhibited NZTE. Furthermore, finite element analysis was employed to investigate the effects of thermal stress within the composites on their thermal expansion performance.

“…SiC nanowires have the advantages of high strength, strong oxidation resistance, good wear resistance, wide band gap, excellent electromagnetic wave absorption performance, and high temperature stability. They have potential applications in field emitters, electromagnetic wave absorbers, microelectronics and light emitters, ceramics and metal composites [ 1 , 2 , 3 , 4 ]. Studies have shown that polymer [ 5 , 6 ], ceramic [ 7 , 8 , 9 , 10 ] and C/C-based [ 11 , 12 ] composites reinforced by SiC nanowires (SiCnws) exhibit higher strength, toughness and thermal shock resistance.…”

In the present study, the effects of SiC nanowires (SiCnws) with diameters of 100 nm, 250 nm and 450 nm on the microstructure and mechanical behavior of 20 vol.% SiCnws/6061Al composites prepared by pressure infiltration were studied. It was found that the interface between SiCnws and Al matrix was well bonded, and no interface product was found. The thicker SiCnws are beneficial to improve the density. In addition, the bamboo-like and bone-like morphologies of SiCnws produce a strong interlocking effect between SiCnws and Al, which helps to improve the strength and plasticity of the material. The tensile strength of the composite prepared by SiCnws with a diameter of 450 nm reached 544 MPa. With a decrease in the diameter of SiCnws, the strengthening effect of SiCnws increases. The yield strength of SiCnws/6061Al composites prepared by 100 nm is 13.4% and 28.5% higher than that of 250 nm and 450 nm, respectively. This shows that, in nano-reinforced composites, the small-size reinforcement has an excellent improvement effect on the properties of the composites. This result has a guiding effect on the subsequent composite structure design.
