Abstract:Porous titanium samples with a porosity of 1.34~15.54% were prepared by a spark plasma sintering (SPS) process at sintering temperatures of 800 °C, 850 °C and 900 °C, and a sintering pressure of 10 MPa. The microstructures and fracture morphology of the samples were investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD) analyses. The compressive strength and elastic modulus were likewise measured. The results showed that no new phase occurred after the samples were sintered, and the mai… Show more
“…Preparing alloy materials with fine grains and uniform microstructure and without macrosegregation can improve the comprehensive mechanical properties of the material. [ 8–12 ] However, the low‐temperature densification process and theoretical research of spark plasma sintering are not perfect and the temperature field inside the sample can only be indirectly monitored. Therefore, no consensus on the sintering mechanism of alloy powder exists.…”
