The order of testing for fulfillment of the conditions of regression analysis is pointed out for the purpose of using the latter correctly when investigating the curve of ultimate strength versus temperature. 2. The question of testing the normality of sample distribution by using special criteria, ...
Results show that the elastic modulus, yield stress and tensile strength decrease with increasing temperature .Based on the experiment results, the functions of the elastic modulus, yield strength and tensile strength versus temperature are represented by polynomial.Weifen Li...
high-manganese steel;hot ductility;cracking;nil strength temperature;nil ductility temperature;ductility recovery temperature 1. Introduction High-manganese austenitic steels are very modern materials used in the automotive industry and belong to the group of advanced high-strength steels. They are character...
To do so, the ultimate strength and stiffness of dampers are plotted versus ρ in Figure 8. As shown in this figure, by increasing the ρ, the ultimate strength and stiffness of both LYP and A36 dampers are reduced but the rate is different. For the parameters after ρ > 0.6, the ...
Steel construction has the highest ratio of strength versus weight, and essentially lighter footprint than conventional construction. Thus, it has a lesser impact on ecology and is less disruptive. Steel – in its entire life cycle has comparatively lesser embodied energy and is thus a GREEN ...
High Strength Low Alloy (HSLA) steels, which contain minor additions of alloying elements (such as manganese, silicon, chromium and nickel), have a lower oxidation rate. Chromium-molybdenum steels are considered to be a better choice for moderate temperature applications. The presence of Mo ...
A high-strength forged part is disclosed which comprises a base phase structure, comprising 30% or more of ferrite in terms of a space factor, and a second phase structure, comprising bainite and/or martensite, and retained austenite having an average gain diameter of 5 μm or less and a ...
For the bridge construction project in the complex environment of the plateau, the high impact resistance and low tough-brittle transition temperature weathering bridge steel with a yield strength of 500 MPa has been developed. The effects of the final c
The Steel Model Library makes it easy to set up time-temperature-transformation (TTT) and continuous-cooling-transformation (CCT) calculations using the TTT and CCT templates that are accessed directly from the homescreen of Thermo-Calc. The templates have several preconfigured settings to help you ...
One limitation on its use is that it softens and loses its strength at increased temperature. It retains its 12.5 bar rating up to 20°C; it should not be used, without reference to the manufacturers, above 50°C, at which temperature its pressure rating is reduced to 8 bar. Installations...
