We present the results of experimental investigation of the damping properties of a manganesendash;copper alloy (75percnt;Mnndash;23percnt;Cundash;2percnt;Ni) obtained by using the electroslag-refining technological procedure and a series of full-scale parts of gas-turbine engines made of this alloy. It was discovered that the decrement of flexural vibrations characterizing the damping capacity of...
By using numerical methods, for specimens of 45 steel subjected to various modes of nitriding in a hydrogen-free atmosphere, we determine the parameters of the process of nitriding guaranteeing the maximum possible level of their damping ability. The results of testing control specimens of 45 steel subjected to the optimal procedure of nitriding revealed practically complete coincidence between the...
