The alloy design for high-nitrogen duplex stainless steels (DSSs) has been received
ascendant attentions due to their excellent strength, ductility and anticorrosion. However, the …

To analyze the good toughness of ultrafine ferrite/cementite steels, the concept of effective
grain size (dEFF) is applied to ductile-to-brittle transition temperature, DBTT, for ultrafine …

Stress–strain curves for ferrite-cementite (FC) steels with ferrite grain sizes between 0.47
and 13.6 μm were studied by tensile tests with strain rates of 103, 100, and 3.3× 10− 4s− 1 at …

In this work, a multi-scale grain structure was obtained in SAF 2205 duplex stainless steel
(DSS) by severe deformation and short-term annealing process. The influence of this …

The objective of this study is to find the effect of ultrafast cooling on microstructure and
mechanical properties of steel with different carbon composition. Steel samples of 6 mm …

With decreasing of grain size in ferritic steels, Lüders elongation becomes larger while work-
hardening is lowered, finally resulting in loss of uniform elongation. This drawback can be …

An ultrafine-grained ferrite/cementite (UGF/C) steel with a local high density of cementite
particles was fabricated through caliber-warm-rolling followed by annealing and resulted in …

For an ultrafine grain ferrite/cementite (UGF/C) steel, the Charpy impact energy was
measured at temperatures from 373K to 4.2 K, and tensile tests were carried out at …

Taylor impact experiments were conducted to examine the mechanical behavior of four
grades of structural steels. The dynamic mechanical response of microalloyed (HSLA) …

We conducted static tensile tests below room temperature for ultrafine-grained ferrite-
cementite (FC) steels with ferrite grain sizes between 0.47 and 1.5 ƒÊm. The change in flow …
