Description
Cutting a superalloy part in several passes is normal machining, but each pass heats and hardens the surface the next pass must cut. Shravan Yadav and Walle Tilahun studied that carry-over in 2026 on Incoloy 925, a nickel alloy, across three milling passes. They measured cutting force, chip shape, roughness, hardness, and the crystal structure of the worked layer.
By the third pass the cutting force ran about a third higher than the first pass, roughness rose by a similar share, and the surface grew harder at every depth. Grain refinement deepened with each pass, though no new crystal phase appeared. Parts cut in early passes resisted wear better, the authors found.
