In this series of tests, the yield strength always overmatches the strength of both weld metal and parent steels, the effect of strength mismatch between parent steel and weld metal on HAZ fracture toughness was small. Weld strength mismatch of 0.95 and 2.15 resulted in HAZ transition temperatures which did not differ by more than 15°C.  (W 397) (1)

Transition temperature = Temperatura de transição

These techniques required knowledge of various material properties, including yield strength, fracture toughness and fatigue crack propagation rates for the operating temperature of the boiler. (Welding 42) (2)

Operating temperature = Temperatura de operação

Despite many previous studies, the accuracy of measurement of the electron temperature and density in the plasma required to calculate the plasma absorption coefficient, still remains open to interpretation. (W 344) (3)

Electron temperature = Temperatura do elétron
