Special Issue Information

Dear Colleagues,

The present Special Issue on the topic of Intermetallics and Interstitials aims to consider the theoretical, experimental, application aspects of intermetallic and interstitial systems, all materials based on the combination of different types of metals (from light ones, such as alkaline, to the heaviest ones, such as actinides), or comprising light p-electron elements in minor amounts to generate unexpected and exceptional chemical, physical, and mechanical properties.

The multiple aspects of Intermetallics and Interstitials will be seamlessly considered and distributed into six sections, each dealing with a different class of properties that chemists, metallurgists, thermodynamicists, mechanicians, physicists, energy transfer specialists, engineers, economists, etc. aim to display and compare in their most recent developments and discoveries.

The present forum offering results of numerical simulation, of a wide panel of experimentations, and of recent achievements on integrated systems should easily demonstrate the forces and the extreme topicality of research and development activities undertaken all around the world during the second decade of the 21st century.

To investigate the high-cycle fatigue (HCF) behavior of TNM alloys, three different microstructures were designed and obtained by different heat treatments. Staircase tests and fatigue tests in a finite life-region were performed to evaluate the fatigue properties. Then, the fracture surfaces were analyzed to study the fracture behavior of TNM alloys with different microstructures. Results showed that the TNM alloys with duplex microstructure possesses the highest fatigue strength and fatigue life, followed by near lamellar TiAl alloys. HCF failure exhibited cleavage fracture morphologies, and multiple facets were generated in the crack initiation region of different TNM alloys. Two different crack initiation modes, subsurface crack nucleation and surface origin, were observed. Both crack initiation modes appeared in near lamellar alloys, while only subsurface crack initiation were obtained in the duplex (DP) alloy. It contributes to the high scatter of S-N data. The HCF failure of TNM alloys was dominated by crack nucleation rather than crack propagation. These findings could provide guidance for optimizing the microstructure and improving the HCF properties of TiAl alloys. Full article
