Crystals Free Full-Text The Effect of Martensitic With the characteristics of high strength and excellent weldability, high-strength low-alloy steel is widely used in automobiles, railway vehicles, bridges and other industries [1,2].In the process of welding steel, it is easy to generate large and centralized residual stresses, which may produce stress corrosion cracking and brittle fracture, seriously reduce the anti-fatigue performance, and

Effect of Micro-alloying Element Boron on the

Feb 25, 2015 · Q690D steel is categorized into the high-strength structural steel, and it is also a kind of low-carbon bainitic steel with excellent mechanical properties such as high strength and high toughness. Q690D plates are extensively applied to the engineering machinery and coal mine machinery, such as hydraulic support, port crane, and platform truck. Experimental and Fracture Model Study of Q690D Steel Feb 04, 2021 · In this paper, Chinese Q690D high strength steel (standard value of yield strength is 690 MPa) was investigated experimentally under quasi-static loading. A series of material specimens with different geometric configurations were processed. Experimental and numerical investigation on Q690 high Jun 01, 2021 · Seismic performance of Q690D steel H-section beam-column bending about weak axis is experimentally studied. Finite element model incorporated with ductile damage for Q690 high strength steel beam-column is established and verified. Parametric study on Q690 high strength steel beam-column is conducted using numerical simulation results.
