This paper deals with the investigation of the microstructure and hardness of steel samples cladded with satellite 6-WC composites by using gas tungsten arc welding (GTAW) process. For this purpose, steel samples were coated with unreinforced and reinforced stellite (by 20, 30 and 40 wt.% WC). The cladded samples were evaluated by metallographic studies, microhardness measurement and X-ray diff...

Assessing the local residual stress and orientation with nanometer resolution within embedded steel grains has remained challenging. Here we use an advanced synchrotron technique, dark field X-ray microscopy to map 3D lattice variations, including both crystallographic strain, two pro-eutectoid ferrite in pearlitic steel. We found variation up 0.5° compressive elastic strain 1.8 × 10?3 are pres...

This paper presents the optimization of CNC turning parameters for EN 16 steel bar using the Grey Taguchi Method. A plan of experiments based on Taguchi’s L27 orthogonal array was established and turning experiments were conducted with prefixed cutting parameters for EN 16 steel bar using tungsten carbide tool. The turning parameters are cutting speed, feed rate and depth of cut and the respons...

This article focuses on the analysis of evolution inclusions present in eutectoid pearlitic steel subjected to a real cold drawing process. To this end, wires belonging different stages manufacture chain were studied, starting from an initial hot rolled bar (not drawn at all). In addition information obtained through visual inspection, quantitative microdefects generated by these was carried ou...

The main contribution of the present work is to investigate the capability of exponential-type constitutive equationto model the warm deformation flow curves of a eutectoid steel in the temperature range of 620-770 °C andat the strain rates in the range of 0.01-10 s-1 conducted on a Gleeble-1500 thermomechanical simulator. Warmdeformation in this temperature range f...

This work reports the performance characteristics of custom thermocouples developed for use in elevated temperatures such as metal casting operations. The scope this research is limited to designed using pyrolytic graphite (PG) primary thermoelement connection with aluminum, copper, steel, and tungsten. Seebeck coefficients sensors were determined from experimental data after heating ~500 °C. C...
