Material and grinding behavior analysis of cemented carbides with cobalt-reduced and cobalt-free binder materials

Abstract Manufacturing companies require large numbers of high-performance cutting tools, which are often made from cemented carbides due to their high hardness and toughness. Cobalt (Co) is typically used as a binder because of its favorable mechanical properties and the high so...

Modification of Surface and Subsurface Properties of Additively Manufactured Inconel 718 Components Through Post-Process and Interlayer Machine Hammer Peening

Additive manufacturing (AM) enables rapid, near-net-shape fabrication with high material efficiency, but the resulting components often exhibit surface roughness, microstructural heterogeneity, and tensile residual stresses that reduce their performance. Machine hammer peening (M...
