• Liquidus temperature, the temperature at which steel of a given composition fully turns to a liquid. Below 723°C we can see Fe3C which is iron-carbide, this is called Cementite which is a ceramic compound of iron and carbon. Steels with less than 0. 8% carbon consist of a structur...
It is shown that the proposed equation accurately predicted the yield strength, elastic modulus, ultimate strength and ultimate strain compared with the test results. Furthermore, stress–strain curves at different temperatures are plotted and a stress–strain model is also proposed. 展开 ...
By combining the YD and YR, the variation in yield strength (Δσ) showed a down-and-up behavior as the Bauschinger effect and strain hardening were dominant at low and high pre-strains, respectively, and plausibly explained the relationship of Δσ and piping strain used in pipe-forming ...
To obtain low yield point steel excellent in toughness as an energy absorbing device in the case of an earthquake of buildings and small in the strain rate dependency of yield points by limiting the presence of yield points, the yield ratio and the strain rate dependency of the yield points ...
• Optimization of growth medium for cell lines or high-yield strains; Feature Stirring system Mechanical sealing system at the top of the fermenter; high-powered stirring oar, antifoam oar; AC electrical machine: infinite speed variation; rpm in the fermente...
For the piping component with pressure rating, the pressure for the condition under consideration is divided by the pressure at the design minimum temperature. Carbon steel NACE-qualified, high-yield carbon steel with minimum 52 ksi yield strength has WPSs that are different from other carbon steel...
For Q&T-processing, there is a slight influence of testing temperature on the yield strength while in case of the Q&P-processed material the yield strength is not affected by the increased temperature. Figure 1 (a) Engineering (tensile) stress-strain curves after Q&T and Q&P heat-...
Yield strength and ultimate tensile strength 5% fractiles and dimensionless reference true stress-strain curves are provided by the Code for base metals and welds. For piping materials, the 16% fractiles of J_(0.2mm) and J-鈻砤 ... Patrick Le Delliou,Bruno Barthelet,Aurore Parrot,... -...
Latching mechanism latched on steering arms is able to release strain on steel cables when in the operation position. The process of latching on and off is stable and without vibration. The bumper is designed on the luminary mounting bracket for avoiding direct damage betwee...
Figure 4a shows engineering stress-strain curves of the Fe18Mn3Ti alloy aged up to 3 h@450 °C. Both, yield stress (YS) and ultimate tensile stress (UTS) systematically increase with increasing aging time indicating precipitation hardening of the martensitic matrix and higher work hardening...
