(i) SZT steels contain considerably reduced [[gamma].sub.R] amount [1-9].
(ii) As a result of both the extensive plastic deformation and spatial limitations, the martensite of SZT steels is clearly refined compared to that developed by room temperature quenching, and it contains enhanced number of lattice defects [1, 5, 10].
In this experiment, a series of magnetic solid acid catalysts SO 2-/ZrO2-Fe3O4 (SCFZ), SO 2-/ZrO2-Fe3O4-MgO (SZM), SO4 2-/ZrO2-Fe3O4-TiO2 (SZT) and SO4 /ZrO2-Fe3O4-ZnO (SZZ) were prepared respectively.
