The need for additive manufacturing (3D printing) to create near net shape components from a wide variety of materials has grown in recent years. There are several methods build various parts by different materials. However, it is challenging construct, the with incompatible combination high temperature and creep resistance using conventional methods. Consequently, purpose this research investi...

Nitriding is a technology that leads to an increase in the utility value of product. It’s most im-portant benefits include increased corrosion resistance, abrasion wear resistance fatigue failure under cyclic loading, and many others. The design suitable nitriding not only on basis empirics requires closer study relationship between structure layer, its properties course particular degrad...

An experimental-numerical methodology was proposed for the parameter identification of constitutive laws, when applied to hot forging. Industrial presses were directly used generate reference experiments identification. The strain and temperature heterogeneity that appears during on-press compression taken into account by an FE-based inverse method. Specific designed heat transfer friction coef...

Abstract The characterization of mechanical vibrations in a hammer forging process is tremendously important parameter for machine design and production engineering. dynamic response to the reaction forces affected by material behaviour, time, spring-damper system foundation. In this research firstly, effect mass ratio coefficient restitution on efficiency were theoretical characterized. intere...

Steelmaking processes require high-performance lining materials with high refractoriness and thermal shock resistance, such as MgO–C bricks. Therefore, the interactions between three industrially fabricated bricks differing in used MgO grade liquid steel are investigated by immersion tests an Al-deoxidized 42CrMo4 at 1600 °C, herein. The trials carried out a casting simulator. Macro- microstruc...

A study has been made of the influence a superimposed mean shear stress on capability some multiaxial high cycle fatigue criteria to predicting behavior 42CrMo4 and 34Cr4 alloy steels. Five selected critical plane-based criteria, namely Matake (M), Susmel & Lazzarin (S&L), Findley (F), Carpinteri Spagnoli (C&S) Liu Mahadevan (L&M), were applied number published experimental resistance limit tes...
