  - TRIBOLOGY INTERNATIONAL - Year 2015

  This paper is devoted to experimental study of capabilities and limitations of grindable thermocouples as applied to polymer materials sliding on metal. Chromel–alumel and chromel–copel grindable thermocouples have been developed and tested for wide ranges of contact pressure and sliding velocity. The background temperature of the sliding surface can be determined as the lower envelope of the signal from the grindable thermocouple....

  - Year 2005

  W pracy przedstawiono światłowodowy sensor czasu przelotu do pomiaru odkształceń i temperatury mogący pracować zarówno w modzie transmisyjnym, jak i odbiciowym. W pomiarach czasu przelotu wykorzystano krótkie impulsy światłowodowe wprowadzane do jednodomowego światłowodu. Pod wpływem czynników zewnętrznych (temperatura, odkształcenie, siła rozciągająca) zmieniała się droga optyczna w światłowodzie, co powodowało zmiany czasu przelotu...

  - INTERNATIONAL JOURNAL OF FATIGUE - Year 2022

  Welding processes often produce high levels of tensile residual stress. Low transformation temperature (LTT) welding wires utilise phase transformation strains to overcome the thermal contraction of a cooling weld. In this paper, the residual stress within each weld was quantified using the milling/strain gauge method, being the strain change measured as the weldment was milled away. The fatigue tests were conducted under uniaxial...

  Badano charakterystyczne cechy degradacji mikrostruktury i właściwości mechanicznych stali 9Cr-1Mo gat. P9 ASTM SA-335 po eksploatacji w piecu rafineryjnym w temperaturze 390-500 stopni C. Wykazano, że po 30 000 godzin wydłużenie obniżyło się o około 30%. Przyczyną spadku wydłużenia były zmiany mikrostruktury związane z umocnieniem osnowy metalicznej przez chrom oraz wynikające z kruchości odpuszczania stali. Większy spadek wydłużenia...
