Features of the thermal magnetic treatment of ticonal 2000 type high-coercivity alloys

High-coercivity alloys with higher Co (24-58.7 wt %) and Ti (up to 16.4 wt %) contents were investigated. Information was obtained on the combined effect of the Co and Ti on the dendritic segregation, the temperature of the solid solution treatment, the start-off temperature of the high-coercivity \alpha_{2} \rightarrow \alpha_{1}+\alpha_{2} decomposition, and the magnetic properties of the alloys after optimum isothermal magnetic treatment (ITMT). The conditions of the ITMT and multistage tempering were investigated. The typical feature of all the alloys is a strong dependence of the magnetic properties upon the ITMT temperature, which should be held to an accuracy of \pm5\deg C. The high coercive force B H_{c} = 2000-2200 Oe and maximum energy product (BH)_{\max} = 4.5-5.5 MG.Oe have been obtained on the alloys with 38 percent Co and 8-8.5 percent Ti as a result of the strict observance of ITMT and tempering conditions.
