The toughness of steel is usvally measured by impact test, and the work done in breaking the specimen of a definite form is expressed as impact value. However, thanks to the effort made by several investigators since 1926, the work done may, in addition, be shown as force-deformation diagram, if necessary. According to this diagram, it may be inferred that, even with two specimens of the same impact value, one may have a comparatively great maximum force with a correspondingly little ultimate deformation, and the other, vice versa. Such an analytical consideration of the impact value is very important in the choice of materials. From this point of view, the forcedeformation curves of several alloy steels in differently heat-treated conditions were obtained in the present investigation. The chief conclusions arrived at are as follows. : 1) Great impact values were generally combined with great ultimate deformations, but, for a definite impact value, there were considerable differences in the value of ultimate deformation. 2) While the impact value was comparatively little, the maximum force increased generally with it, but when the impact value became greater, the maximum force decreased with it. Similar to the previous case, for a definite impact vaule, the maximum force greatly differed. 3) The steel marked No.6 in this note, when hardened and tempered properly, gave a very different form of the forcedeformation curve from those of the other steels of almost the same impact value, its maximum force being especially great. 4) No general relation was found between the maximum force and the Brinell hardness-number, but with those specimens of the same impact value greater than about 10kg-m as measured in this test, these two quantities appeared to vary jointly in the same sense.
