摘要This study investigated the sublimation of Mn and microstructural evolution of binary Fe/Mn compacts sintered at various temperatures in a vacuum. A high sintering temperature or a lengthy holding time promotes powder densification. Due to sublimation of Mn, the weight loss of the compacts mainly occurs during the isothermal holding stage of the sintering process; it increases significantly from 1.5 wt.% for sintering at 1000 degrees C to 8.6 wt.% at 1200 degrees C. For the first time, the phase evolution in the binary elemental compacts was clarified using in situ neutron diffraction. The gamma-austenite phase emerges during temperature ramping to 536 degrees C, while beta-Mn and alpha-Fe disappear at 774 degrees C and 881 degrees C. The neutron diffraction also revealed that single phase gamma-austenite forms in the Fe-Mn compacts if the temperature is >= 881 degrees C. (C) 2018 Elsevier B.V. All rights reserved.
