What common production processes are adopted for high-temperature alloys?

Primary manufacturing techniques include vacuum induction melting and vacuum arc remelting to eliminate internal impurities. Forging refines grains to boost comprehensive strength; precision investment casting makes complex hollow turbine blades. Powder metallurgy produces ultra-fine grain alloys with superior high-temperature durability for high-load aviation parts. Each process adjusts internal microstructure to fit different temperature and load working standards.
