2. 1. Mechanical Properties of Welds at Creep Activation Temperatures

   Author : Henrik C.M. Andersson-Östling; Rolf Sandström; Kamran Nikbin; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; creep; creep crack propagation; OFHC copper; welds; nuclear waste disposal; creep modeling; Materials science; Teknisk materialvetenskap;

   Abstract : Welds in materials intended for service at temperatures above the creep activation temperature often develop damage before the base metal. The weld is a discontinuity in the material and stresses and strains often accumulate in the weld. Knowledge of the properties of the weld is essential to the safe operation of the component containing the weld. READ MORE

4. 2. Thermal Cycling, Creep- and Tensile Testing of Cast Exhaust Materials at Elevated Temperatures

   Author : Christian Öberg; Stefan Jonsson; Henrik Östling; KTH; []
   Keywords : creep; constant-load; thermal cycling; tensile test; cast materials; cast iron; exhaust materials.; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : An exhaust manifold of a truck engine is subjected to tough conditions. As the truck is started, operated and shut down, it becomes subjected to thermal cycling up to around 800°C. At such high temperatures, corrosion, fatigue and creep are active degradation mechanisms. READ MORE
