Description
This paper investigates the effect of boron alloying on austenite decomposition in 0.80C-0.50Mn-0.25Si-0.20Cr wire grades. This investigation is part of a research effort to use boron alloying to minimize nitrogen strain aging in high-carbon wire rod grades processed in electric arc furnaces. The dilatometric signal during austenite transformation was measured in a GLEEBLE® system for different cooling rates. A microstructural investigation was conducted to study pro-eutectoid constituents and the presence of martensite.
