摘要: Abstract Sintered NdFeB-based permanent magnets were fabricated by spark plasma sintering (SPS) and a conventional method to investigate the mechanical magnetic properties. The experimental results showed that sintered NdFeB magnet prepared (SPS NdFeB) possesses better properties compared conventionally one, of which maximum value bending strength Vickers hardness was 402.3 MPa 778.1 MPa, respectively. effects temperature on investigated. It shown firstly increases then decreases with increase in certain range. investigations microstructures indicated unique mechanism SPS process is responsible for improvement NdFeB. Furthermore, relations between relevant microstructure have been analyzed based fact.
