Influence of the Sintering Agglomeration Regime on the Magnetic Properties and Hardness of Specimens Made of Powder Steels 30NM and 30N2M

摘要

The dependences of the magnetic properties and hardness of powder-sintered steels 30NM and 30N2M with different densities on the sintering temperature are studied. It is shown that, for spec-imens with the studied compositions, there is a correlation between the combined parameter produced by the coercive force and saturation magnetization and the steel tempering temperature and hardness. In recent years, in mechanical engineering, powder metallurgy technology has been used to fabricate steel parts [1]. This technology is rather simple and allows fabrication of products with complicated shapes with maximum use of the metal. It is widely used to fabricate parts from structural carbon steels based on iron powders.
