Journal ArticleDOI
9%Cr heat resistant steels: Alloy design, microstructure evolution and creep response at 650 °C
TL;DR: In this paper, two sets of alloys were produced: 9%Cr alloys with 0.1%C and 0.05%C (always wt) and 9%cr alloys containing ∼0.03% Ti with 0 1%C/0.5%C.
Journal ArticleDOI
The role of Laves phase on microstructure evolution and creep strength of novel 9%Cr heat resistant steels
TL;DR: In this paper, the influence of Laves phase formation and growth kinetics on the creep strength at 650°C of two different 9%Cr heat resistant steels of the authors' design was investigated.
Journal ArticleDOI
Investigations on coarsening of MX and M23C6 precipitates in 12% Cr creep resistant steels assisted by computational thermodynamics
TL;DR: In this article, the evolution of precipitates at different creep times was determined experimentally using scanning transmission electron microscopy (STEM). Phase equilibria were calculated with Thermocalc and simulations of coarsening of precipitate were carried out with Dictra.
Journal ArticleDOI
Investigations on the growth kinetics of Laves phase precipitates in 12% Cr creep-resistant steels: Experimental and DICTRA calculations
TL;DR: In this paper, the growth kinetics of Laves phase precipitates (type Fe2W) in the early stage of creep (650°C for 10,000h) in two 12% Cr ferrite-martensitic steels has been investigated.
Journal ArticleDOI
Design and characterization of microstructure evolution during creep of 12% Cr heat resistant steels

TL;DR: In this article, a detailed characterization of the microstructure evolution at different creep times (100MPa/650°C/8000h) was carried out by scanning transmission electron microscopy (STEM).
