| Abstract: | Through optical and electron microscopy to study the various micro-phases in different cooling processes to titanium bearing low carbon steels containing fine non-metallic inclusions,it is observed that the ferrite fine microstructure has much effect on their mechanical properties.The existence and amount of small isolated martensite between the acicular ferrite play an important role in determining the tensile strength and low temperature impact toughness of the steels. |
