Laser Ultrasonic Technique to Non-Destructively Detect Cracks on a Ni-Based Self-Fluxing Alloy Fabricated Using Directed Energy Deposition (DED): Japanese version of the paper published in “Materials Transactions, 61(10): 1994-2001 (2020)”

Miniaturization of bearing rollers used in autos and robots will require a manufacturing system that combines a deposition method that can fabricate thin jigs without defects and a non-destructive inspection method that can detect cracks on such jigs. Here, we are developing a system that uses direc...
