Impact of tool magnetization on changes in the surface layer of forging tools [PDF]

Archives of Metallurgy and Materials, 2019
The paper presents a description of the phenomena occurring on the surface of the forging dies. A detailed analysis was made of 24 pre-forging dies due to the most intensive wear in this operation.
