A modified 9Cr–1Mo steel has been exposed to three separate normalization treatments ie
at 950° C, 1025° C and 1100° C from As-received (normalized at 1050° C and tempered at …

A modified 9Cr–1Mo steel received in normalized and tempered condition has been
subjected to four different hot-rolling treatments at different rolling temperatures (1050° C …

The present review begins with a brief introduction to the development of ferritic and ferritic-
martensitic steels summarizing the development history in each country. The main thrust is …

Toughness is a major concern for low-carbon microalloyed steels. In this work, the impact
fracture behavior of two low-carbon Ti-V microalloyed steels was investigated in order to …

Three hot-rolled TWIP steels with different grain size were obtained by changing final rolling
temperatures. The results show that the recrystallization microstructure can be obtained at …

Room temperature fatigue crack growth (FCG) testing was conducted after thermal aging for
500 and 5000h at 823K and for 500h at 923K, on 9% Cr–1% Mo steel normalized at 1323K …

The effect of thermal aging on the ductile-brittle transition behavior has been assessed for a
modified 9Cr-1Mo steel (P91) using the reference temperature approach under dynamic …

For the Alloy 617, the effect of aging on the fracture energy degradation has been
investigated after aging for different time periods at 1023 K (750° C). A sharp reduction in …

In this paper, some of the older and newer Charpy-fracture toughness correlations have
been examined and new correlations have been developed for predicting the ASTM E-1921 …

Samples from normalized and tempered modified 9Cr–1Mo steel, were normalized at three
different temperatures and rolled at four different temperatures and subsequently tempered …
