Residual Stress Field Analysis and Prediction in Nitrided Tool Steel

摘要: Residual stresses are present in engineering components as an unintended consequence of manufacturing processes, but they also deliberately introduced to beneficial effect during surface procedures. Plasma nitriding is a process particular importance for forming tools and dies, giving significant advantages wear, fatigue resistance through the generation near-surface compressive residual stresses. A precise knowledge level distribution that exist necessary accurate design prediction component's resistance. However, measurement not always possible, which especially true tools. Therefore, other methods stress evaluation required. Results this investigation show depth plasma nitrided tool steel increase with time temperature. On hand, experimental data indicates that...
