Title:
METHOD FOR MANUFACTURING COMPONENT USING ADDITIVE MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2016102257
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a method for manufacturing a component, which is optimized for its use by local variations of its microstructure.SOLUTION: A method includes the steps of: preparing a data set for being used in an additive manufacturing process; manufacturing the component according to the data set; and subjecting the component to a heat treatment. At least two different volume regions are defined within the component; at least two different process parameters are chosen; and the additive manufacturing method is executed, resulting in a first recrystallization behavior in a first volume region with one of the at least two process parameters being used while manufacturing the first volume region, and resulting in a second recrystallization behavior in a second volume region with the other of the at least two process parameters being used while manufacturing the second volume region. The component is subjected to a heat treatment, with a holding temperature, wherein the holding temperature lies above a recrystallization temperature of at least one of the at least two volume regions.SELECTED DRAWING: Figure 4
