摘要

Microstructure and magnetocaloric effects in LaFe10.8 Co0.7 Si1.5 C0.2 compound produced by induction furnace were investigated. NaZn13 -type structure (1:13) formed in LaFe10.8 Co0.7 Si1.5 C0.2 compound after being annealed at 1373 K for only 6 h. As annealing time increases, the grains grow up irregularly. A nearly single 1:13 phase is obtained after being annealed for 2 days. Annealing time is significantly reduced compared with that in conventional bulk LaFe_13-xSi_x compounds. The short annealing time is of great advantage to application. The maximum magnetic entropy change of this compound is -4.9 J/K Kg under a magnetic field of 2 T and relative cooling power is 172.2 J/Kg.
