The energy flow network should be designed according to the concept of the primary circuit in graph theory (eg, the secondary energy and waste heat must be timely and fully recovered so that the energy flow network should be connected with a simple primary circuit); 6. Solution of optimized ...
The interface of the aged tensile test sample can be seen in Fig. 13. Indications of the melt pools can be seen clearly on both sides of the sample and the deformation zone can be distinguished due to its response to the etchant. The maraging steel on the left side is fully aged (HV...
Thereby, find the optimal set of welding mode parameters to fabricate the test samples. Using the Weibull distribution function and Loga normal distribution function, the fatigue graph and fatigue regression equation are built to evaluate the fatigue strength of ANSI 304 steel pipe welds.Nguyen, ...
摘要: TESTS CARRIED OUT ON 12 PROTOTYPE AND 34 MODEL BEAMS ENABLED SIMPLE FORMULAS TO BE DEVELOPED TO ASSESS THE ULTIMATE STRENGTH OF THE DOWEL AND ALLOW A LOAD-DISPLACEMENT GRAPH TO BE PRODUCED. IT WAS ESTIMATED THAT THE DOWEL GENERALLY CARRIED ABOUT 12% OF THE TOTAL SHEAR FORCE ON THE BE...
where α and n are constants obtained from experimental tensile test of the stainless steel strip and σ0 is the axial stress in the stainless steel at 0.2% strain. Hence, in the present study, the values determined for α and n are 0.05 and 9.7, respectively. Figure 1 shows the stress...
Microstructure and mechanical properties of steel 3Cr 1Mo 1/4V have been studied by metallograph,TEM and XRD. The results show that the secondary hardening occurs at 550 ℃. The strength and hardness decrease with the increasing of the tempering temperature and time, meanwhile the plasticity incre...
For example, in a notch tensile test a material is said to be notch brittle if its notch strength is less than its tensile strength; otherwise, it is said to be notch ductile. Notch SensitivityA measure of the reduction in strength of a metal caused by the presence of stress concentration...
Stress-strain graph of the (a) hot band and (b) batch annealed steels Full size image Table IV Mechanical Properties of the Hot Band and Processed Steel, Tested at Room Temperature (298 K, 25 °C) Full size table Interrupted tensile tests followed by quantitative XRD were performed on both...
The graph bars on the material properties cards below compare S30452 stainless steel to: wrought austenitic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relev...
