“…This observation is in a reasonable agreement with the experimental results obtained previously for other, non-HEA bcc metallic materials such as different steels, Nb and Ta. For these materials  varies between 0.17 and 0.60[35][36][37][38]. The relatively low value of  for the present HEA material is in line with the low strain hardening observed on the true stress -true strain curve.…”

This paper presents changes in mechanical properties and microstructure of the material of components of a power station boiler made of X10CrWMoVNb9-2 (P92) steel after long--term thermal ageing. Mechanical properties and microstructure were examined on material in initial heat treatment condition and after long-term thermal ageing up to 100,000 h at 600 and 650• C. The microstructure was observed using a scanning and transmission electron microscope. The examinations of steel microstructure and mechanical properties in initial heat treatment condition have confirmed that the requirements for this steel are met. Longterm thermal ageing at a temperature similar to the operating one as well as mechanical properties and microstructure examinations allowed to assess the effect of long-term impact of temperature on the properties and microstructure of P92 steel. The presented method can be used for evaluation and qualification of microstructural changes in power station boiler components operating under creep conditions.

An oxide dispersion strengthened (ODS) ferritic steel with nanometric grain size has been produced by low-energy mechanical alloying (MA) of steel powder (Fe-14Cr-1W-0.4Ti) mixed with Y 2 O 3 particles (0.3 wt %) and successive hot extrusion (HE). The material exhibits superior mechanical properties with respect to the unreinforced steel up to 400 • C; then such differences tend to progressively decrease and at 700 • C yield stress (YS) and ultimate tensile strength (UTS) values are very close. The microstructure and mechanical behaviour have been compared with those of ODS steels prepared by the most common process, high-energy MA, consolidation through hot isostatic pressing (HIP) or hot extrusion (HE), annealing around 1100 • C for 1-2 h. The main strengthening mechanisms have been examined and discussed to explain the different behaviour. In addition, heat treatments in the range 1050-1150 • C were carried out and a microstructural evolution with a relevant hardness decrease has been observed. TEM observations evidenced defect recovery and partial grain coarsening owing to the not perfectly homogeneous distribution of oxide particles.
