Abstract
A review is presented of liquid phase sintering in ferrous powder metallurgy. The application of the concept to the Fe–Cu and Fe–Cu–C systems is described. The effect of additions such as tin, boron, and copper based masteralloys are discussed, as is the contribution of iron powder type, particularly in relation to the use of very fine powders. Fe–P and Fe–P–C materials are discussed. The contribution of liquid phase sintering to the development of masteralloys is highlighted. Examples of the industrial application of liquid phase sintering techniques are described. Structural engineering component production by masteralloy techniques is considered, together with its contribution to the assembled composite camshaft concept. Finally, the problems inherent in making more industrial use of the liquid phase sintering systems discussed are outlined and some recommendations for further study are made. PM/0334
