Influence of Carbon Potential Control during Sintering on Properties of Low Alloyed Steel
Replacing traditional manufacturing methods with more efficient methods have been possible by the development of high performance materials hence leading to higher profitability and repeatability of quality.Carbon potential during sintering should be controlled for not only avoiding decarburization,but also providing carburizing and faster cooling of the sintered parts during the sintering process to obtain higher mechanical properties in a cost-effective way.The carbon content after the sintering is critical for materials containing elements with higher oxygen affinity,like Cr,thus requiring a very strict sintering atmosphere.Therefore,the need for a better understanding about the influence of carbon potential control during sintering is becoming increasingly important for cost effective manufacturing of Powder Metal(PM)components to achieve high mechanical properties.In this paper,the carbon potential control by newly developed system,SINTERFLEX(R),was studied for different low alloy materials.The relationship between sintering atmosphere and carbon potential gas for different low alloy materials were studied.The influence of different carbon potentials on the mechanical properties,combined with rapid cooling rates,will be discussed.
