Abstract:

The objective of this work was to study the effect of the heat treatment and further operation aging on the stereological parameters (size, quantity and volume fraction) of precipitates within ferrite grains of a creep-resistant 1.25Cr0.5Mo steel after long-term operation. The heat treatment was similar to the treatment that is carried out in industrial steam... More

Abstract:

In this study, the forming behaviour of dissimilar welded blanks was studied. Welded blanks were prepared with friction stir welding processwith different types of tool pin profiles. Welded blanks were developed with fixedfriction stir welding process parameters by varying the tool pin profiles. The forming behaviour of welded blanks were analyzed with the limiting dome... More

Abstract:

Titanium powder was rapidly solidified by using shock-wave consolidation technique. The critical parameters were controlled by intrumented detonics and pin-oscillography. The compacted specimens were investigated for crystal structure and microstructural strengthening by using standard diagnostic techniques. The density of the final product was found to be greater than 96% of the theoretical value. X-ray diffraction... More

Abstract:

In the present investigation a series of MoO₃-Fe₃O₄ nanocomposite material such as MoO₃, Fe₃O₄, Beta cyclodextrin (b-CD) doped MoO₃-Fe₃O₄ and Graphite doped MoO₃-Fe₃O₄ have been synthesized successfully by co-precipitation method. Synthesized nanomaterials were characterized in detail by XRD, FT-IR, TEM-HRTEM, UV-Vis DRS techniques. The crystalline size was in the range of 10±2 nm. The activity of the... More
