The Effect of Vibrations (Sonic and Subsonic Frequencies) during the Period of Solidification on the Mechanical Properties of Castings of Gas Turbine Materials with Special Reference to H. R. Crown Max and Nimonic C. 75

Test castings were designed to produce data which would help in the production of gas turbine blades as castings. For castings in H. R. Crown Max the investigation is limited to the effect of subsonic frequencies and range of amplitudes; but in the experiments conducted on Nimonic C. 75, both sub-sonic and sonic ranges of frequency were...
