Inspection of the Metal Microstructure in Laser-Surfaced Rollers

The microstructure and crystalline structure of laser-surfaced 9Kh2MF and 8Kh3SMFA steel samples are studied. Samples are taken from the working rollers of the reversible rolling mill at PAO Uralmashzavod. Sealing of surface cracks in the rollers by means of a laser is regarded as an effective repai...
