DESCRIPTION:Speakers: Mainford Toga (Manicaland State University of Applie
 d Sciences)\nManganese steel is a high-carbon alloy known for its exceptio
 nal toughness\, ductility\, and wear resistance. A high manganese grades c
 omprising approximately 22-44% manganese and 1% carbon\, exhibits remarkab
 le work-hardening properties\, making it ideal for high-impact application
 s. While the metal grade specification does not indicate any chromium and 
 molybdenum elements\, these were found in some melts due to the scrap mate
 rial used. When in moderate concentrations not to cause significant carbid
 e formation\, they influenced the material microstructure\, with sub-grain
 s formed within some grains. These carbide formers were also found to be a
 ssociated with smaller grain structure\, which improves the mechanical pro
 perties of the material according the Hall-Petch equation. This unique mic
 rostructure of manganese steel contributes to its ability to withstand hea
 vy stress and abrasive conditions\, commonly found in mining\, constructio
 n\, and rail industries.\n\nhttps://events.saip.org.za/event/249/contribut
