In order to make clear the mechanism of the reduction degradation of iron ore sinter, the macro strain in the skeletal hematite during reduction was measured. The results obtained are as follows : (1) The strain is scarcely remained in the skeletal hematite in the iron ore sinter. (2) The difference of the mechanism of the reduction degradation of iron ore sinter is made clear in some kinds of reducing gas such as carbon monoxide, hydrogen and the gas mixture of carbon monoxide and carbon dioxide (35%). (3) In the case of the reduction by CO and CO+CO_2 (35%), the crack is formed immediately after reaching the maximum strain, 0.5∿0.6, in the crystal, but the strain curve is not obtained during reduction by H_2 gas.
