Effect of Neodymium Content on Creep Properties of 9Cr-3Co-3W-Nd-B Steel

نویسندگان

چکیده

The effects of the neodymium content on creep properties and microstructures 9Cr-3Co-3W-Nd-B steel were investigated. Neodymium had a mild effect rupture strength at contents up to 0.056 mass%. This suggested that compounds solid-dissolved minimal in uniformly creep-deformed parts after normalizing tempering heat treatment. On other hand, reduction area was improved by addition neodymium. Creep occurred prior austenite grain boundaries without Therefore, conclusively adhered segregated sulfur suppress formation cracks.

Effect of Post-Sintering Annealing Treatment on Magnetic Properties of Some Nd Fe b Based Magnets

Effects of post-sintering annealing treatment between 300 and 1000ºC for up to 8 hrs time periods followed by either furnace cooling (FC) or air-cooling (AC) on the hard magnetic properties of some Nd-Fe-B based sintered magnets was investigated. It was shown that the intrinsic coercivity (Hci), second quadrant demagnetization loop shape and thus the energy density (BH)max varied considerably a...
