Abstract In general, the grains of ceramic materials tend to grow and coarsen with prolonging holding time at high temperatures due grain boundary migration. this study, high‐entropy diboride ceramics composed (Hf 0.2 Zr Ta V Nb )B 2 were prepared using spark plasma sintering (SPS) 30 MPa. Notably, refinement increased times during SPS process was unexpectedly observed. Specifically, sizes refined from approximately 6 µm (synthesized 1900°C for 5 min) around 10 min). This intriguing...
In this article, Fe–8.5Mn–1.5Al medium‐manganese steel is taken as the research object, and Gleeble 3500 thermal simulation testing machine used to conduct isothermal compression at different deformation temperatures, strain rates, strains in its austenite ferrite two‐phase zone. A constitutive model a dynamic recrystallization volume fraction for materials are established, finite‐element method simulate temperature, equivalent strain, distribution regions of workpiece under conditions. By...
Hot blanking process not only produces a variety of fine parts have comprehensive mechanical properties, but also solve the difficulties in piercing and trimming press-hardened parts. To explore optimal hot investigate effects some technological parameters on phase-transformation dimensional accuracy parts, several different temperatures (450 °C, 500 550 600 650 700 750 800 °C) die clearances (25%, 20%, 18%, 16%, 14%, 12%, 10%, 8%) were used B1500HS steel. The results show that diameters...

Abstract Boron steel B1500HS deforms at elevated temperature under the complete austenite state, and it accords with 0-angle necking type, irrespective of strain state on left- or right-hand side forming limit diagram (FLD), which is in accordance M–K simplified model. However, constitutive equation significantly affects prediction FLD sheet metal. In this study, modified Arrhenius model, including deformation activation energy temperature, describing hot sample austenitic microstructure...
The response of electro-magneto-elastic long fiber composites containing periodically distributed reinforced phases under antiplane shear load coupled with inplane electromagnetic load, which lead to the deformation mode, is dealt with. There are three different materials in unit cell (3-phase model), a rigorous analytical method developed by using generalized eigenstrains concept integrated doubly quasiperiodic Riemann boundary value problem theory. expressions fields each phase obtained....
The springback of metals after plastic deformation is the main factor affecting final shape and dimensional accuracy formed parts. However, behavior aluminum alloys bulk-deformed at evaluated temperature has not been fully clarified, accurate models are urgently required for precision forming light-weight In this study, AA2099, AA6061 AA7050 were selected as experimental materials to explore general laws develop unified models. Single-pass isothermal hot compression unloading tests carried...
