→There is a phenomenon in which the transformation rate of the 7-phase (magnetic phase) becomes slow, and conversely becomes faster when the amount of Ni added is large. Judging from the above,
P and Ni are thought to have a large influence on the energy states of the main constituent elements Mn and AI, and these influences are due to the effect of warm plastic working that causes pongee grain formation. , more promoted. These things mean that Hc
It is thought that this is working in the direction of increase. Figures 4 and 5

, (BH) is expressed as a ratio to max. From FIG. 4, Hc shows almost the same large value as Hc in the Ni-P alloy, regardless of the amount of Ti added. From Figure 5, 0.0
1STiSO. It can be seen that (BH)max is significantly improved by adding Ti in No. 5. When we observed the structure of these alloys after heat treatment in the metal head microstructure, we found that P-Ni-
The Ti-added alloy has smaller crystal grains than the Ni-added alloy and the Ni-P-added alloy, and it is presumed that the improvement in (BH)max is due to the refinement of the crystal grains due to the addition of Ti. From the above, the optimal addition amount of P, Ni, and Ti is 0<P≦0.
