FIELD: technological processes.
SUBSTANCE: invention relates to metal forming and can be used in making articles of gas turbine engine stator casing parts from nickel-based heat-resistant alloy. Vacuum arc remelting ingot 500 mm in diameter is upset. Then, the besieged billet is pierced, the billet is drawn and rolled with increasing its height and diameter and hot rolling. As a result, rectangular cross-section initial workpiece is produced. Profiled billet is produced by hot forging of initial circular billet. Then it is heat treated and machined.
EFFECT: improved structure and mechanical properties of the finished product.
