Multilayer Steel Composite Prepared by Rolling

Two types of multilayer material have been studied: a self-sharpening composite with a wear-resistant layer in the middle and soft outer layers, and a layered macrocomposite made by alternating two layers with a different graphite content. It is established that the powder rolling method and appropriate thermomechanical treatment make it possible to prepare materials with markedly different layer-by-layer hardness and high hardness for the pearlitic component. These materials may be used for preparing cutting tools with a self-sharpening effect and high operating life.
