Local microstructural evolution and the role of residual stresses in the phase stability of a laser powder bed fused cold-work tool steel

Control of the metallographic and mechanical properties of Cr8 cold-work die steel by laser continuous/dispersed quenching

“…Cr8 steel (ASTM D3M) is a commonly used alloy tool steel, due to its high hardenability and excellent comprehensive mechanical properties, which widely was used in the manufacture of cold-work mold, such as draw dies, stamping dies, cold extrusion dies and powder compacting dies, etc [1][2][3][4]. Meanwhile, it is also placed on high expectation in the modern high-performance vehicle high-strength steel parts stamping production [2,5].…”
