The effect of tempforming temperature on the microstructure and mechanical properties, especially impact toughness, of the S700MC-type high-strength low-carbon steel was investigated. Tempforming at temperatures of 923 and 973 K was characterized by the development of ultrafine-grained layered microstructure consisting of grains highly elongated in the rolling direction with the transverse grain size of 530 and 920 nm, respectively.

Abstract:
Resistance spot welding is one of the most used welding technologies for joining of thin, deep drawn steel sheets in automotive industry. The condition of electrodes may have significant impact on the resulting weld quality, therefore it is necessary to check the electrodes´ wear that otherwise may cause creation of specific defects in the weld joints.

Abstract:
Small punch creep test (SPC) is an alternative method for obtaining information about the material properties of steels and alloys when only a limited amount of test material is available that does not make it possible to perform conventional creep and/or stress rupture tests. SPCT testing can also be used for determination of the residual life of critical components of a fossil fuelled power plant. [..]
