Special Issue Information

Dear Colleagues,

Most instances of structural failures in engineering can be attributed to High Cycle Fatigue phenomena. Thus, a profound understanding of the fatigue and fracture behaviors of the materials and structural elements is indispensable for enhancing their longevity and safety.

Innovative materials and processes, such as additively manufactured materials, have spurred the use of novel methodologies to analyze intricate configurations. Consequently, these advancements necessitate specialized approaches to simulate the fracture responses, ensuring compliance with stringent safety requirements.

This Special Issue of Materials is dedicated to the scrutiny of High Cycle Fatigue and fracture behavior in engineering materials and components. The emphasis is placed on investigating estimations and providing a platform for presenting the recent breakthroughs in this domain. The publication serves as a conduit for disseminating knowledge and fostering discussions on the evolving landscape of fatigue and fracture analysis, contributing to the continual improvement of structural durability and safety standards.

This Special Issue intends to cover several topics, which include, but are not limited to:

  • Fracture mechanics approaches for fatigue assessment of materials and components;
  • Defect assessment and high cycle fatigue resistance;
  • Fatigue and fracture of metallic alloys fabricated through additive manufacturing;
  • Novel fatigue design criteria of mechanical components;
  • Experimental methods in fracture mechanics.

The application potential of additive manufacturing nickel-based superalloys in aeroengines and gas turbines is extensive, and evaluating their mechanical properties is crucial for promoting the engineering application in load-bearing components. In this study, Hastelloy X alloy was prepared using the laser powder bed fusion process combined with solution heat treatment. The tensile and high cycle fatigue properties were experimentally investigated at room temperature as well as two typical elevated temperatures, 650 °C and 815 °C. It was found that, during elevated-temperature tensile deformation, the alloy exhibits significant serrated flow behavior, primarily observed during the initial stage of plastic deformation at 650 °C but occurring throughout the entire plastic deformation process at 815 °C. Notably, when deformation is small, sawtooth fluctuations are significantly higher at 815 °C compared to 650 °C. Irregular subsurface lack of fusion defects serve as primary sources for fatigue crack initiation in this alloy including both single-source and multi-source initiation mechanisms; moreover, oxidation on fracture surfaces is more prone to occur at elevated temperatures, particularly at 815 °C.
