Description
Ho-In Jeong and four co-authors compare plain and laser-assisted cutting of a 3D-printed high-entropy alloy. The alloy, mixing titanium, niobium, chromium, vanadium, and nickel, keeps strength at high heat, which suits extreme service. It was printed by directed energy deposition, then machined two ways.
Their 2024 study found the alloy's heat conduction and heat capacity rose with temperature, while tensile strength fell, with sharp softening past 800 degrees Celsius. Laser-assisted machining pre-softens the cut zone with heat, and it cut the needed force by 60 percent against conventional machining. Neither method changed the alloy's chemistry. The authors argue laser help is essential for finishing such stubborn alloys for real use.
