| Abstract: | The preparation,structure and properties of Fe-N compounds were investigated. A solid-gasreaction was conducted using iron powder with NH3/H2 gas. The effects of different quenching media on thestructures and properties of reaction products were studied. The results showed that ice-water quenching almost entirely result in N-austenite powder and that N-martensite is available through the quenching with dry ice and liquid nitrogen. Fe16 Ni2-bearing nitride POwder can be obtained through tempering at 150 C. Also,apure and homogeneous Fe2N powder is available through the solid-gas reaction at 540-590 C with a magne tizability up to 190 Am2/kg. |
