The ambiguity of the splitting effect on X80 low-carbon microalloyed pipeline steels’ tendency towards brittle fracture prompted an experimental study impact toughness scattering based multiple Charpy tests in a temperature range from 20 °C to −100 °C. A fractographic analysis large number fractured samples was carried out. relationships between toughness, deformability and characteristics were...

Some forensic in situ investigations, such as those needed in transportation (for aviation, maritime, road, or rail accidents) or for parts working under harsh conditions (e.g., pipes or turbines) would benefit from a method/technique that distinguishes ductile from brittle fractures of metals—as material defects are one of the potential causes of incidents. Nowadays, the gold standard in mater...

‌‌‌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...
