This research analyzed the impact of fine-grained content on the mechanical characteristics of coarse-grained soil in the river valley region of southeastern Xizang under freeze-thaw cycle circumstances via indoor tests, and modified the Duncan-Zhang model based on the test results. A total of six different coarse-grai...
Expansive soils pose persistent challenges to geotechnical design due to their high swelling potential and sensitivity to moisture variations. Thermal stabilization has recently emerged as a promising alternative to conventional chemical treatment, yet its implications for soil strength mechanisms remain insufficiently...
To investigate the effect of grain size on the tensile deformation behavior and dynamic softening mechanisms of GH2907 alloy at 500 and 600 °C, fine‐grained (FG) and coarse‐grained (CG) specimens were prepared via solution treatment. High‐temperature tensile tests were performed at 500 and 600 °C, combined with mechani...
Grain breakage under high stress conditions can significantly affect the hydro-mechanical behavior of granular materials by altering grain size distribution, pore structure, porosity, and permeability. This study investigates these coupled effects in two sands with contrasting mineralogical characteristics, namely Host...
This study investigates the effects of austenitizing temperature on the microstructure and mechanical properties of 55SiCr steel under rapid heating conditions using electromagnetic induction heat treatment. The results indicate that the microstructure of 55SiCr steel tempered at 400 °C primarily consists of tempered...
To elucidate austenite grain coarsening and mixed-grain formation in continuously cast Nb–Ti microalloyed steel during high-temperature holding, high-temperature holding experiments, Clyne–Kurz microsegregation calculations, Thermo-Calc equilibrium precipitation analysis, Gladman pinning calculations, and multi-order-p...
