Room temperature oxidation of Ni-23at%Cr alloy has been studied. Chromium is preferentially oxidized on Ni/Cr alloy surface after 1 to 2 L of oxygen exposure. Reaction of Ni with oxygen occurs more slowly than the Cr/O2 reaction, but much more rapidly than for pure Ni. Chromium oxide (...
Fig.15 Tensile tests at room temperature and 400 ℃ of Cr-coated Zr alloy and un-coated Zr alloy cladding[50] 西屋公司初步采用原位 TEM 技术研究了冷喷涂 技术所制备的 Cr 涂层内部辐照缺陷,试验条件分别 设置为辐照温度 320 ℃、辐照粒子 Kr2+(...
17 proposed the room- and high-temperature Mo equivalents for Ti–43Al, used to control the β0 and β fractions, respectively. In order to achieve better modification of the alloy, a further understanding on the behavior of γ–β/β0 structural phase transition is still needed. In this ...
values of the two studies can be attributed to several factors. The material on which USS response was measured was irradiated with neutrons at around 300 °C which could have partially annealed the material, compared to the materials in this study which were ion-irradiated at room temperature....
The effect of thickness on the room temperature (RT) mode I fracture behavior of V–4Cr–4Ti has been investigated. Mode I fracture properties were measured from J-integral tests of compact tension (CT) specimens ranging in thickness from 6.4 to 25.4 mm. All specimens were machined in the...
The calculated γ of FeCrRuSi at room temperature and zero pressure is 2.353. Finally, the evolution of Debye temperature Θ with temperature at some fixed pressures has been investigated, as shown in Fig. 10. It can be seen that Θ is nearly constant from 0 to 300 K and then ...

Cr-Mn-N ASS has a low stacking fault energy (SFE) at room temperature, and it is prone to strain-induced transformation into ε-martensite (ε-M) and α'-martensite (α'-M) [14,15]. Moallemi et al. [16] reported that the SIM transformation in 201 stainless steel had a prominent...
An alloy designed for use in gas turbine engines which has high strength and a low coefficient of thermal expansion is disclosed. The alloy may contain in weight percent 7% to 9% ch
