Investigation of Functional Graded Steel Parts Produced by Selective Laser Melting

Abstract:

The article presents the results of a study on the additive manufacturing of functional graded steel parts. Studies have been carried out on the possibility of growing blanks from two steels simultaneously – tool steel H13 and stainless steel 316L. The study of the microstructure of the transition from one steel to another showed that the transition layer is smooth and is about 200 microns thick. The mechanical properties in the transition layer are distributed over the gradient and smoothly change from one material to another. The structure and properties of the transition layer after heat treatment and hot isostatic pressing are shown.
