Resource-Saving Technology for Preparing Nickel Superalloy VZh175 Using Substandard Waste

详细

A resource-saving technology is presented for processing up to 100% waste, including substandard material, of wrought alloy VZh175 for turbine disks. The technology has been developed in the scientific-production complex of VIAM and makes it possible the prepare alloy from waste no worse than that produced from fresh charge materials with respect to alloying content, impurities, structure, and mechanical properties. The cost is lower by 20–30% compared with that of alloy melted by industrial technology using 50% standard waste.
