TLDR
In this paper, the influence of thermal aging on room temperature tensile properties of the forging remained similar to that reported for thin section 9Cr-1Mo steel, whereas the reduction in area exhibited a decrease in the value with increasing thermal ageing.About:

Comparison of various 9–12%Cr steels under fatigue and creep-fatigue loadings at high temperature
Benjamin Fournier,F. Dalle,Maxime Sauzay,J. Longour,M. Salvi,C. Caës,Ivan Tournié,Pierre-François Giroux,S.-H. Kim +8 more
TL;DR: In this article, the authors compared the cyclic behavior of various 9-12%Cr steels, both commercial grades and optimized materials, in terms of creep strength and found that all the tempered ferritic-martensitic steels suffer from a cyclic softening effect linked to the coarsening of the subgrains and laths.

Creep rupture behavior of Grade 91 steel
TL;DR: In this article, the deformation behavior of grade 91 steel was studied in the temperature range of 600-700°C and at stresses of 35-350 MPa, and the data were analyzed in terms of Monkman-Grant relation and Larson-Miller parameter.

Creep-fatigue-oxidation interactions in a 9Cr-1Mo martensitic steel. Part III: Lifetime prediction
Benjamin Fournier,Maxime Sauzay,C. Caës,Michel Noblecourt,Michel Mottot,Annick Bougault,Véronique Rabeau,Jiří Man,O. Gillia,P. Lemoine,André Pineau +10 more
TL;DR: In this paper, a model devoted to the prediction of the high temperature creep-fatigue lifetime of modified 9Cr-1Mo martensitic steels is proposed, which is built on the basis of the physical mechanisms responsible for damage due to the interaction of creep, fatigue and oxidation.

Influence of the temperature on the tensile behaviour of a modified 9Cr–1Mo T91 martensitic steel
TL;DR: In this article, the tensile behavior of a modified 9Cr-1Mo T91 martensitic steel is investigated for temperatures between 300 and 700 K. Loading/unloading tensile tests are carried out to investigate the evolution of the flow parameters and the different flow stress components with temperature.

Grain refinement to improve impact toughness in 9Cr–1Mo steel through a double austenitization treatment
TL;DR: In this article, a two-stage normalizing (1323 K/2/h/water quench) and tempering (1023 K 2/2 h/air cool) treatment was used to obtain a homogeneous tempered martensite microstructure with a smaller prior-austenite grain size of 12μm.

Serrated plastic flow
TL;DR: In this paper, the authors present an assessment of the current understanding of the phenomenon of serrated plastic flow, which manifests itself as serrations, load drops, jerkiness or other discontinuities in the stress-strain curves obtained in constant extension rate tensile tests, and as sudden bursts of strain in constant loading rate tests and in constant load (stress) creep tests (the so called staircase creep).

Repeated yielding in tin bronze alloys
TL;DR: In this paper, the index m in Van Bueren's (1955) equation C v = B ∊m, which relates the concentration of vacancies (C v) in a strained metal to the instantaneous plastic strain (∊), was evaluated in solid solutions of 1.7 at.% tin in copper.

Prediction of microstructural states in Cr-Mo steels using phase evolution diagrams
TL;DR: In this paper, a new concept of phase evolution diagram was introduced and demonstrated its utility in predicting the subsequent microstructural states and assessing the previous thermal history, based only on the information of the composition of the parent matrix.

Serrated flow in gold-indium alloys
TL;DR: In this paper, the characteristics of serrated flow in gold-indium solid solution alloys are studied over a range of strain rates and temperatures. But the authors focus on two types of serrations, the general Type A locking serrations and the Type C unlocking serrations.

Hydrogen and temper embrittlement in 9Cr–1Mo steel
C. A. Hippsley,N. P. Haworth +1 more
TL;DR: In this article, the synergism between hydrogen embrittlement and temper embrittlements has been investigated in a 9Cr-1Mo martensitic steel and a detailed examination was made of associated changes in fracture mechanism, precipitate microstructure, and interfacial and precipitate chemistry.
