Carburized Cr-Ni steel is widely used in the manufacture of components many fields due to excellent performance, which service life has been a concern. In order investigate high-cycle-fatigue and very-high-cycle-fatigue properties carburized gear steel, axial loading fatigue tests were performed by QBG-100 with stress ratios −1, 0 0.3. The Generalized Pareto distribution was evaluate inclusion ...

The Vanadis® 8 is a tool steel used in the manufacture of dies, punches and tools. It has high carbon content combined with chromium, molybdenum vanadium, presents good performance its mechanical properties. Usually, chips obtained by machining are sold to companies that use remelting. However, this technique considered expensive harmful environment. Therefore, work aimed analyze efficiency add...

Currently, many researchers pay attention to studying the influence of process variables on quality metal products after manufacture. The most common methods metalworking are forming processes, in which a high degree deformation, uneven plastic and elevated temperatures utilized. In cases manufacturing using these methods, self-balanced system residual stresses is formed that significantly affe...
