Research output: Contribution to journalArticlepeer-review


Direct resistance heating of specimens was used for high-temperature strength testing in a protective atmosphere. The details of the design of temperature control and loading equipment are described. By using long specimens the test temperature of the central gauge length can be kept satisfactorily constant. The method is well suited for creep testing provided the cross section decreases homogeneously during primary and steady-state creep. High-temperature tensile tests can also be performed, providing correct data on yield and ultimate tensile stresses provided the strength of the material decreases monotonically with temperature.
