The mechanical properties of iron & steel are effected by temperature. Mechanical tests were made at high temperature range, from 20℃ to 1, 000℃. The contents of this paper are as follows. 1. History 2. Impact bending test at high temperature 3. Impact tensile test at high temperature 4. Ordinal tensile test at high temperature 5. Repeated bending test at high temperature 6, Summary. Materials used are ; -6 plain carbon steels of various carbon content, from 0.1% to 1.2% ; nickel steel ; nickel-chrome steels ; Ni-Cr-molybdenum steel ; stainless steels for turbine blade ; alloy steels for valve of aero-engine. Impact bending test was operated on the apparatus specially constructed to fit on the Izod impact testing machine & special device was applied to impact the specimen just at the temperature wanted. The relationship between carbon content, temperature & impact figure was determined. Impact tensile test at high temperature was made on another new apparatus and the results were compared with those of slow tensile test and impact bending test. Special testing machine for repeated bending at high temperature was also constructed and some research was made with various carbon steels. The comparison of each mechanical properties is described and the theoretical interpretation is given.
