Effect of Nanobainite Content on the Dry Sliding Wear Behavior of an Al-Alloyed High Carbon Steel with Nanobainitic Microstructure [PDF]
Materials, 2019 In this work, a multiphase microstructure consisting of nanobainte, martensite, undissolved spherical carbide, and retained blocky austenite has been prepared in an Al-alloyed high carbon steel. The effect of the amount of nanobainite on the dry sliding wear behavior of the steel is studied using a pin-on-disc tester with loads ranging from 25–75 N ...

Nanobainite Generated in Low‐ and Medium‐Carbon Steels via an Economical Alloying Strategy [PDF]
steel research international, Volume 93, Issue 6, June 2022., 2022 A low‐cost strategy for generating low‐ and medium‐C steel alloys relying on Al additions to accelerate the transformation is investigated. Increasing Al in isothermally and continuously cooled conditions refines the lamellar thickness, lowers both the incubation and transformation times but causes a slight drop in tensile properties.
