AbstractDispersion strengthening of the most wear-resistant soft magnetic alloy Sendust (Fe-9.5 wt.%Si -5.5 wt.% Al, HV=5000 MPa) by carbide and boride phases allowed to increase its wear-resistance by a factor of 2 to 3. Hardness of the dispersion strengthened alloys is HV=5500–6250 MPa. The changes in grain size, ordering and hardness of the Sendust and two dispersion strengthened alloys have been studied after spinning and various regimes of laser melting. Both types of rapid solidification caused a significant decrease of both the solid solution grain size and the size of carbide and boride phases. While spinning only significantly decreased the amount of ordered Fe3(Si,Al) phase in all the alloys, laser melting completely suppressed the ordering. The hardness of the boride strengthened alloy increased up to 7550 MPa after laser melting.

In this paper, we studied the grain size and volume fraction change of [Formula: see text]-Fe(Si) nanocrystalline phase as a function of Cu, Mo and Si content in Fe[Formula: see text]Cu[Formula: see text]Mo3Si[Formula: see text]B9, Fe[Formula: see text]Cu1Mo[Formula: see text]Si[Formula: see text]B9, Fe[Formula: see text]Cu1Mo3Si[Formula: see text]B[Formula: see text], and also the annealing temperature and time in Fe[Formula: see text]Cu1Mo3Si[Formula: see text]B9 alloy. Cu is an element promoting ultrafine structure and crystallization progresses, it causes the grain size of the [Formula: see text]-Fe(Si) phase to decrease suddenly, the volume fraction of [Formula: see text]-Fe(Si) phase to increase only by adding 0.5 at.% Cu. Also, Mo causes the grain size of [Formula: see text]-Fe(Si) phase to decrease like Cu, while suppressing the increase of the volume fraction of [Formula: see text]-Fe(Si) phase, Si has no little effect on the grain size of [Formula: see text]-Fe(Si) phase, diffuses into the inner part of [Formula: see text]-Fe(Si) phase upto Si 13.5 at.%, but suddenly increases grain size above Si 13.5 at.%. The microstructure of Fe[Formula: see text]Cu1Mo3Si[Formula: see text]B9 alloy is nearly completed at 520[Formula: see text]C for about 20 min, the grain size is approximately 13.8–14.1 nm, the volume fraction of [Formula: see text]-Fe(Si) phase is within 61–66%, initial permeability at 1 kHz is within 59,800–61,100.
