      abstract     = {Longitudinal and shear wave velocities in pure tungsten and
                      tungsten fiber-reinforced tungsten (Wf/W) composites were
                      studied by laser ultrasonic measurements. The samples were
                      produced from powders or powder/fiber mixtures by spark
                      plasma sintering process. It was found that sintering
                      temperature, as a processing parameter, has the largest
                      effect. Higher sintering temperatures result in faster wave
                      velocities. For example, longitudinal wave velocities and
                      their standard deviations in sintered W at 1800 °C and 2000
                      °C were 4834 ± 53 m s−1 and 5043 ± 47 m s−1. In
                      comparison, the average longitudinal wave velocity for a
                      polycrystalline reference W was 5227 ± 5 m s−1. The
                      values for Wf/W composites fall between the two sintered
                      samples. However, the thicker Yttria (Y2O3) fiber/matrix
                      interface resulted in faster wave velocities. The elastic
                      moduli were calculated from the sound velocities using
                      average density measurements. The standard relations for
                      isotropic, homogeneous material were used. It was found that
                      the shear, bulk, Young's modulus are $80\%–90\%$ of the
                      values for polycrystalline tungsten, while the temperature
                      dependency from 25 °C to 450 °C is similar.},
