## Description

- description: 'Spark plasma sintering (SPS) is a promising method for producing titanium
    components from powder but a limitation is that high sintering temperatures (>900 °C)
    are normally required to eliminate porosity. Herein, the SPS of commercially pure
    titanium powder is reported using both cyclic and constant uniaxial pressure and
    compare densification, microstructure, and mechanical behavior. The following
    parameters are varied: sintering temperature, TS, 400 to 900 °C; cyclic and constant
    pressures, 100 to 500 MPa; with and without an isothermal dwell of 60 min at TS.
    The mechanical behavior is determined by bend and tensile testing. It is demonstrated
    that the application of cyclic pressure (cyclic-SPS) gives superior densification
    over the range of parameters investigated compared with a constant pressure. Bend
    testing reveals improved ductility after cyclic-SPS compared with a constant pressure.
    The dwell at TS further improves mechanical properties, giving excellent tensile
    ductility and strength. Consequently, at the ultralow temperature of 500 °C, nearly
    fully dense, ductile, titanium is achieved. It is shown that cyclic pressure enhances
    the degree of powder compaction at room temperature, and mechanisms are proposed
    to rationalize the effect of cyclic-SPS on enhancing the rates of densification
    and sintering as the temperature increases during processing.'
