Influence of Strain Rate on Tensile Characteristics of SUS304 Metastable Austenitic Stainless SteelXifeng LI,Jun CHEN,Liyan YE,Wei DING,Pengchao SONGDepartment of Plasticity Technology,School... austenitic stainless steel sheets have been investigated during tensile process at diferent strain rates at room temperature.The yield stress continuously increases with strain rates due to low fraction......
hot-rolled sheet is improved, but the tensile ductility decreases slightly both at room and elevate temperature with the increase of solution temperature from 990 ℃ to 1 010 ℃. The tensile strength decreases with aging temperature increasing from 815 ℃ to 850 ℃, but the tensile ductility does not change obviously. No significant differences of tensile properties are observed after solution treatment......

alloy have a moderate level of tensile ductility (about 12.7%) and a significant strain hardening capability up to tensile failure. After aged at 373 K for 48 h, the ECAPed alloy increases its hardness (about HV201) and tensile ductility (about 14 %) further. The TEM results show that the ECAPed 2024 Al alloy presents a plate structure (about 50-100 nm) with high density of dislocation......
diffraction. Results revealed that the ultimate tensile strength and ductility of the pre-strained Ni20Cr microwires simultaneously increased with increasing strain rate.
