The effect of "GASCARBUSINT" on tensile properties of sintered steels

The paper presents the tensile behavior of sintered steels developed through a new process called gascarbusintering (GCS), consisting of carburizing in gas (CH4) of a set of iron based powder compacts followed by sintering. The influence of compaction pressure and dwell time at the carburizing temperature on the tensile properties of steels processed by GCS is investigated. Mechanical tests revealed that investigated GCS steels show Rm ranging from (180-315) MPa, Young's modulus from (125-150) GPa, with values increasing with increasing compaction pressures (from 400 to 600 MPa), and with increasing dwell time of carburizing (from 120 to 240 minutes).
