TLDR
A 35MnSiCrNiAlMo bainitic steel whose mechanical properties approached those of 140-maraging steel was developed in this paper, where the steel was continuously cooled from a temperature slightly higher than its martensite start temperature (Ms) to Ms−−20°C at a cooling rate of 0.5°Cmin−1, after which the overall mechanical properties were better than those of austempered samples at any constant temperature.About:

Zongbiao Dai,Hao Chen,Ran Ding,Qi Lu,Chi Zhang,Zhigang Yang,Sybrand van der Zwaag,Sybrand van der Zwaag +7 more
TL;DR: In this paper, the authors provide a brief review of the desired microstructures for Transformation-induced plasticity (TRIP), Carbide-free Bainitic (CFB), Quenching & Partitioning (Q&P), and Medium Manganese steels followed by comprehensive discussions on the phase transformations to be used in their creation.

Development of the low temperature bainite
Mohamed Soliman,Heinz Palkowski +1 more
TL;DR: In this paper, the possibility of obtaining steels with nano-size plates of bainitic-ferrite by isothermal transformation at low temperature is set forth, and an overview of the so far studied alloying strategies and processing methods adopted for developing the low temperature bainite together with addressing some examined technological themes.

The dislocation distribution, flow stress, and stored energy in cold-worked polycrystalline silver
J. E. Bailey,P. B. Hirsch +1 more
TL;DR: In this paper, the distribution and densities of dislocations, determined by electron transmission microscopy, flow stress and stored energy measurements (by microcalorimetry) on cold-worked polycrystalline silver are correlated with each other.

Very strong bainite
TL;DR: A steel with an ultimate tensile strength of 2500 MPa, a hardness at 600-670 HV and toughness in excess of 30-40 MPa/m 1/2 is the result of exciting new developments with bainite as discussed by the authors.

Quantitative measurement of deformation-induced martensite in 304 stainless steel by X-ray diffraction
TL;DR: In this paper, a single X-ray diffraction scan was used for identifying and evaluating deformation-induced transformation in 304 austenitic stainless steel and the initial stage of transformation in this steel was most likely dominated by e−martensite formation.

Acceleration of Low-temperature Bainite
TL;DR: In this article, the authors report methods for accelerating the rate of reaction without compromising strength, and show that bainitic ferrite plates produced by transformation at low temperatures can be as thin as 20 nm with a hardness in excess of 650 HV.
