Magnetic disk substrate and method of manufacturing the same |
| abstract |
A magnetic disk substrate composition 0.5 wt % to 1.0 wt % of Mo, 0.03 wt % to 0.5 wt % of O+2N+0.75C, and a balance of Ti. The alloy sheet having a composition of above range is cold-rolled at a rolling ratio of 30% or more to form a magnetic disk substrate material, and the material is thermal-flattened under the following condition: n n 500≦T≦-(150/11)·t+7850/11 n n n 1≦t n n where T represents a thermal-flattening temperature (°C.), and t represents a thermal-flattening time (houre), thereby obtaining a magnetic disk substrate having the average grain size of 30 μm or less. |
