High-Temperature Oxidation Resistance of Alumina-Forming Austenitic Stainless Steels Optimized by Refractory Metal Alloying

“…(Ni eq 2 + Cr eq 2 ) 1/2 is the distance from point zero to the composition point on Schaeffler constitution diagram, which reflects the amount of alloying elements in the corresponding compositions. [13,18,23] according to the conversion equations between the hardness and tensile strength of austenitic stainless steels [45].…”

“…According to the tensile test results of ORNL at room temperature, the yield and ultimate strength of the solutionized AFA4-1 (4Al/0.6Nb/0.1Ti) are, respectively, 270 MPa and 600 MPa [13]; those of solutionized B-1.0 (Fe-2.87Al-0.14Si-1.01Nb-20.11Ni-1.93Mn-14.24Cr-2.00Mo-0.99W-0.47Cu-0.10C) are, respectively, 261 MPa and 613 MPa [18]; those of 20Ni-(3-4)Al-(0.6-1)Nb based AFA stainless steels are 237-282 MPa (yield strength/solutionizing state), 568-660 MPa (ultimate strength/solutionizing state), 422-434 MPa (yield strength/ aging state) and 744-811 MPa (ultimate strength/aging state) [23]. For easy comparison, the tensile results of ORNL are converted to hardness, referring to the study on the conversion relationship between the hardness and tensile strength of austenitic stainless steels by Chen et al [45] Figure 7). It should be noted that both the ONRL's and our designed series-1 alloys have a higher content of C (0.1 wt.…”

Microstructure, mechanical properties, and electrical conductivity of Mg–8Li–2Y–Zn/Al multilayered composites fabricated by cross asynchronous accumulative roll bonding

“… 18 Furthermore, in the study of rolling pressure for bimetallic rolling deformation, it was found that bimetals with relatively large layer thicknesses must be compounded under the condition of a large amount of depression, and it is difficult to compound in simultaneous cumulative stack rolling, while asynchronous rolling can obtain larger deformation under the same rolling pressure to achieve the compounding of metals with relatively large layer thickness, so the researchers proposed an asynchronous accumulative roll bonding (AARB) process. 19,20 As such, the combination of the CARB process and the AARB process has become a new preparation method cross asynchronous accumulative roll bonding (CAARB) process, which is beneficial for improving the interface of the heterogeneous metal composite.…”

Inhomogeneous Deformation of Multilayered Roll-Bonded Brass/Cu Composites

“…This is because with this method multilayered materials on a bulk scale can be obtained. In the past decade, deformation of the ARB-processed composite materials has been widely investigated [9][10][11][12][13][14][15][16][17]. In addition to the plane strain compression loading applied by the rollers, the ARB-processed metal surfaces also undergo shear deformation, due to the large friction between the metal and the roll surfaces.…”
