Mechanical properties and corrosion resistance of ultrafine grained austenitic stainless steel processed by hydrostatic extrusion
Abstract
Thematerial studied is a commercially available 316LVMstainless steel with an initial grain size of 30 μm. To refinethe microstructure down to the nanoscale, hot (at 1000 °C) and room temperature hydrostatic extrusion were applied with a total true strain of 1.4. An annealed sample with coarse grains of 35 μm in diameter was used as a reference sample. The results indicate that after hot hydrostatic extrusion, themicrostructure consisted mainly of cells with tangled dislocation walls, while after room temperature hydrostatic extrusion, twins of variouswidth and shear bands could be distinguished. Hydrostatic extrusion is also an efficientway to tailor the corrosion resistance and mechanical properties of 316LVM stainless steel. Performed at room temperature,hydrostatic extrusion resulted in an ultra-high-strengthmaterial with limited but sufficient ductility. Performed at high temperature, hydrostatic extrusion resulted in a material with a very good combination of strength (approximately 900MPa) and ductility (elongation to failure higher than 20%). Both hydrostatically extruded steels maintained good passivation behavior in 0.1MH2SO4. In the presence of chloride ions, susceptibility to localizedattack increased for the steel extruded at room temperature, but did not change for the hot-extruded steel.
