Over the last 50 years, many researchers have contributed significantly towards understanding the Masing/non-Masing behavior of materials. However, there has been no review article or scientific report published to date that highlights the progress made in this domain. This article presents a state-ofthe-art comprehensive review and analysis of the Masing/non-Masing behavior of materials under low cycle fatigue loading. Understanding of Masing/ non-Masing behavior is important for the development of fatigue-resistant materials, prediction of fatigue life, and constitutive modeling and simulation. The influence of various factors such as stacking fault energy, temperature, strain amplitude, and loading conditions on Masing/non-Masing behavior has been summarized in this article. The literature pertaining to the internal microstructural changes observed in different materials by various researchers has been collected and compiled. The different methods of analyzing Masing/ non-Masing behavior reported in the open literature are assessed and presented. The importance/significance of Masing/non-Masing behavior in constitutive modeling and fatigue life prediction has also been highlighted. Finally, conclusions based on the review and the potential problems required to be resolved in the future are also pointed out.
