Elastic properties of polycrystalline Sc, Re, Ru and Pt-21 Ir

Physical Metallurgy

“…The value calculated from the elastic constants is 7-52 x 10 10 N/m 2 , and this value has been chosen as the best value. It is noted that the value reported by Brown et al (1966) is in excellent agreement with the chosen value, but that of Geiselman (1962) is somewhat larger.…”

“…They also noted that all of the compressibility values reported for the five substances measured by Stephens are consistently smaller than the values reported by others for the same material. An adiabatic compressibility value of 14-96 x 10~* 12 m 2 /N (14-88 x 10~7cm 2 /kg) was determined by Brown et al (1966). Since the difference between the isothermal and adiabatic (x is0 -Xad = 0*158 x 10 _12 m 2 /N or 0-161 x 10~7 cm 2 /kg) this value of Brown et aL is essentially the same as that of Stephens (1964).…”

“…A) two bulk experimental measurements have been made. Geiselman (1962) and Brown et al (1966) give values of 8-01 x 10 10 and 7-55 x 10 10 N/m 2 , respectively. The value calculated from the elastic constants is 7-52 x 10 10 N/m 2 , and this value has been chosen as the best value.…”

“…The shear modulus has been measured by Brown et al (1966) and has been calculated from elastic constants (see above, Section 14. A).…”

Effect of Mo content on thermal and mechanical properties of Mo–Ru–Rh–Pd alloys

“…The sound velocity, elastic moduli and Debye temperatures of the alloys are summarized in Table 2 together with the data on polycrystalline Ru [36]. The elastic moduli of the alloys are nearly equal to those of Ru.…”
