Microstructural changes and ferrite phase transformation under shock loading, between 8.5 GPa 17.5 GPa, in a hot-rolled Lean Duplex Stainless Steel (commercially known as LDX 2101) were investigated as-received pre-deformed conditions. The latter condition was considered to distinguish classical deformation twins at high strain rates from those associated the reversible transformation. Plate im...

Effects of tempering temperature on tensile and hole expansion properties in a dual-phase C–Mn steel were investigated. The ultimate tensile strength and yield strength decreased and elongations increased with an increase of tempering temperature. The hole expansion property increased significantly at the tempering temperature ranging from 200 to 300 8C and did not show significant difference w...

In order to meet the increasing requirements of automotive industry for material strength grades and performance, application advanced highstrength steel panels, represented by dual-phase steel, in lightweight vehicle bodies is increasing. Resistance spot welding main joining process body manufacturing. How improve tensile fatigue performance resistance joints great significance structure body....
