O. crystal constant of rare earth 485nmz, and (Fe, convex) G upward in the lattice constant of c O. 454nm [6J, mismatch of less than 10%, so, rare earth atoms enriched in this direction is easy. Thus preventing crystal growth in this direction,<a href="http://www.toryburchshoes-home.com/tory-burch-flats/tory-burch-reva-milk-white-flat" target="_blank" class="postlink">tory burch white flats</a>, so that regular carbide shape,<a href="http://www.toryburch-retailshop.com" target="_blank" class="postlink">tory burch shoes sale</a>, so that the mechanical properties, especially impact toughness from the experimental results to improve the impact toughness of materials can be seen from the original 3. ~ 6J/erY increased to 4.47j / evE, a relatively large increase. Microstructure shown in Figure l photos can be seen. To increase RE and add O. Figure la 4% Ce compared in Figure lc. Spheroidizing white and carbides tend to significantly refined. Meanwhile, as the martensite matrix was refined poultry 0o4% Ce addition on a 2.4C a 17Cr-I. 8Mo-l0Cu Taijin performance 203d with Ce06% Figure l photo cx4O0】 metallographic samples, nitric acid etching of alcohol can be seen from Table 2, with the addition of a further increase of rare earth, sintered products of the indicators and tends to go down that excess of rare earth sintered products in the addition of rare earth oxide content increased, due to rare earth oxide together easily in the grain boundary, thus worsening the continuity of the matrix, the impact toughness of the material decrease In addition, rare earth oxides are high melting point and extremely stable compound, hindered the process of sintering densification process, resulting in an increase in sintered porous residual affect of mechanical properties. Figure l (c ) can be seen that the increase in the amount of rare earth added, making the carbide shape deterioration, which is a reduction in material properties cause can not be ignored. 4 Conclusions 1) milling system of adding rare earth elements,<a href="http://www.toryburchsales.org" target="_blank" class="postlink">tory burch sale</a>, can reduce the powder system, the active oxygen content, so that the lower sintering temperature and microstructure refinement, can improve the mechanical properties of sintered products. 2) The amount of rare earth elements can be refined by adding the amount of carbide, its shape regular, help to improve the impact toughness of materials, the appropriate amount of RE addition of a 0.6% to 0.4%. Continue to increase the dosage to worsen the mechanical properties of sintered products 3) resistance test showed that the addition of 0.4% rare earth samples of rare earth elements than the sample without resistance increased 3,6 times.
