METHOD OF MANUFACTURING WELDS WITH GOOD CREEP PROPERTIES IN POLYCRYSTALLINE NICKEL-BASED SUPERALLOYS

摘要

It is a kind of manufacture welding unit polycrystalline nickel based super alloy have fabulous croop property method be disclosed. The manufacturing method of the present invention includes: that step 1 is rapid, for generating plastic deformation, by the way that external force butt welding machine is added in the nickel based super alloy and above-mentioned welding unit for welding the connection unit of the substrate formed; Second step, the surface for being divided into the substrate of fine grain by heating the welding unit of refinement fine grain for handling the fusion splicing devices. ;The 2014 of copyright KIPO submissions;[Reference numerals] (AA) starts; Make the welding unit of elegant particulate (BB); (S110) plastic deformation is generated, by the way that external force is added to welding unit; (S121) welding unit of solution processing; (S122) in the welding unit of aging process
