The influence of the solidification rate of the melt was investigated for amorphous metallic systems based on
iron: Fe60Co7Cr4V2W1Mo1Nb1B20C2Si2
(HB-4), Fe68Mn1Mo4Cr2C7P10B5Si2Cu0.3W0.3Al0.3 (HBPC-4), Fe55Ni8Co6Mo4Cr2V1Al2P9C6B5Si2
(NHRP-6). Rapidly cooled
(105 K·s-1) alloys in the form
of tapes with a thickness
of 35 μm showed lower microhardness and higher plasticity. The surface composition
of bulk samples
cooled at a rate of 103 K·s-1
differed
from that of tape samples,
due to slow diffusion and formation
of two or three phases. Some samples were enriched with Cr,
V, W, Mo, Nb, or Mn.
Bulk alloys showed higher
microhardness and lower plasticity than tape
samples.
