Effect of sintering process on mechanical properties of uniaxial tensile sintered nano-silver component.

In the paper, the mechanical properties of uniaxial tensile sintered nano-silver components were investigated by molecular dynamics method, and the effects of sintering pressure and temperature on them were analyzed. The sintered body was obtained by sintering three adjacent cubes, and the sintered nano-silver component under uniaxial tension was cut from the existing sintered body. The results show that the potential energy decreases while the kinetic energy has a jump. The higher the sintering pressure, the earlier the nano-silver sintering begins. Temperature has little effect on sintering time. When sintered nano-silver components are uniaxial tensile, the greater the sintering pressure, the greater the rising absolute value of the potential energy, and the greater the yield stress. When the sintering temperature is 250 °C, the variation of potential energy is large and the yield stress is high. The paper aims to supplement and guide the mechanical properties of sintered nano-silver. • The mechanical properties of sintered nano-silver components were simulated. • Uniaxial tension rather than sintering process is analyzed. • The influence of sintering pressure and temperature on it was investigated. • The greater the sintering pressure, the greater the yield stress. • When the sintering temperature is 250 °C, the yield stress is high.
