- Abstract
Low carbon steels wide range using materials, chemical composition and physical properties controls by using heat treatment process that including heating and then cool by appropriate quenching mediums. The effects of polyethylene glycol diluted with water as quenching medium on the mechanical properties (hardness, compression) and microstructural properties of low carbon steel were investigated with the aim at improving their compatibility with polymer quenching. The tested samples were prepared and subjected to heat treatment process used electrical resistance furnace soaked for 1 hour and then quenched in polyethylene (PE) diluted with water in controlled percentages of PE% (25%, 35%,45%). Used digital microhardness and universal test machine resulted an enhancement in their mechanical properties, they though (PE) gives good cool rates. The dominant of martensitic phase in microstructures resulting in their enhancement of low carbon steel properties. The hardness improvement about 83.5% as illustrated with this paper, also the compressive strength improved about 23.3% with this work. Also, an enhancement of surface cracks was observed with increasing (PE) percentage. It is assumed that polyethylene solution will help to develop high performance of low carbon steel properties for industrial fields applications.
