Factors Influencing the Wear Behavior of Sintered Steels

A review was made on the research progress of wear behavior of sintered steels in recent years.Wear is not an intrinsic property of sintered steels,which is strongly influenced by the wear test conditions.Howerver,many other factors that determine the mechanical properties of sintered steels also affect the wear behavior.Porosity has different effects on the wear of sintered steels depending on the application conditions.Under dry sliding condition ,higher porosity results in lower wear resistance.The influence of microstructures on wear resistance is in the order;Carbide,martensite,bainite and lamellar pearlite,The wear resistance increases with hardness,but this relationship changes with the porosity and microstructures of sintered steels.     

Publisher–Society partnerships to further image accessibility and global inclusivity in the Humanities and Social Sciences: Comparing top-down and bottom-up approaches

• Collaboration between publishers and learned society partners can accelerate and amplify DEIA outcomes.
• 97 HSS titles have adopted alt-text publication workflows and this change has been welcomed by journal authors and editors.
• Efforts to promote global inclusivity do not always result in greater membership diversity, retention and growth.
• Top-down, publisher-led DEIA initiatives are effective when they are aligned strategically to pre-existing society initiatives.
• Bottom-up, member-led DEIA initiatives benefit from publisher support to mitigate financial and time-based barriers to active participation.
• To reliably track DEIA outcomes, publishers ought to adopt systematic data collection strategies through initiatives like C4 and the Joint Commitment.
