Abstract
Under conditions of Klimov engineering enterprise, industrial results are obtained for the first time for developing casting technology for small single-crystal uncooled GTE turbine rotor blades of a new heatresistant alloy VZhM7 with reduced density and with a crystal orientation of <001>. Structural models are developed for blocks of blades with seeds and heat-resistant alloy melting and pouring in a unit for directional solidification. Test batches of blade castings are obtained with a yield of finished single-crystal structure of not less than 90% under VIAM pilot plant conditions, and 80% under conditions of Klimov engineering enterprise. The structure and phase properties are given for single-crystal blade material after casting, hot isostatic pressing, and subsequent heat treatment. Data are provided for fatigue tests on blades with crystal orientation <001>.
