‌‌‌Fatigue behavior of a vanadium microalloy steel has been studied in this research. Here, microstructure constituents were considered which essentially are dependent on the heat treatment conditions. The results of high cycle fatigue tests revealed that heat treatment procedure and cooling rates have significant effects on fatigue properties. Optimal heat treatment cycle of the microalloyed s...

One of the most important properties microalloyed steels is different microstructures which are obtained by changing thermomechanical processing parameters and steel composition. The control microstructure such as grain size, precipitates, dislocation structure inclusions highly effective to determine mechanical steels. strengthening can be done processesing due increase nucleation sides via ma...

An experimental approach is presented for the measurement of wear that is common in the threading of cold-forged steel. In this work, the first objective is to measure wear on various types of roll taps manufactured to tapping holes in microalloyed HR45 steel. Different geometries and levels of wear are tested and measured. Taking their geometry as the critical factor, the types of forming tap ...

Quenching-partitioning-tempering (Q-P-T) heat treatment is a relatively novel approach to attain excellent ductility in high-strength steels. In the present work, microstructural evolution and mechanical properties of low carbon microalloyed advanced steel were systematically investigated after Q-P-T process. The was explored by employing X-ray diffraction, transmission electron microscopy scan...
