(PDF) Design of a novel Mn-based 1 GPa duplex stainless

The results reveal a small Samples were examined by ECCI and EBSD using a dependence of the mechanical properties on the texture, i.e. a small mechanical anisotropy. The conventional duplex stainless steel 1.4362, eld emission gun scanning electron microscope. which is shown as a reference material in (a and b), has the exact Samples for EFFECT OF CUBE TEXTURE ON THE PLANAR Since the r value is tightly related with texture, the texture evolution from hot roll slab (HRS) to final T4P temper was analyzed with X ray diffraction (XRD) to find the reason for the high anisotropy. Besides, the cold rolling reduction (CRR) was varied in the laboratory to modify the texture distribution, i.e., the planar anisotropy.

Effect of austenitic texture on tensile behavior of lean

Jan 10, 2017 · 1. Introduction. Duplex stainless steels (DSS) have microstructures that consist of similar fractions of face centered cubic (fcc) austenite and body centered cubic (bcc) ferrite .By virtue of constructive property combinations between the two constituent phases, they usually show an excellent balance in mechanical properties as well as corrosion resistance. Effect of crystallographic texture on the planar The effect of crystallographic texture on planar anisotropy in tension and low cycle fatigue was investigated for samples machined along 0, 45 and 90° angle with respect to the rolling direction of hot rolled and annealed 316 stainless steel sheet using electron backscatter diffraction. Effects of load partitioning and texture on the plastic Apr 03, 2019 · The plastic anisotropies of two hot-rolled Lean Duplex Stainless Steels (commercially known as LDX 2101 and LDX 2404) were investigated by applying compressive strains, at 10 3 s 1 rate, along the rolling- and transverse-directions (RD and TD). The microstructural changes were elucidated by Electron Backscatter Diffraction (EBSD) as a function of strain level and loading direction.

The microstructures of the warm-rolled specimens consisted of flattened wavy grains. The texture evolution during rolling in the

Effect of Nitrogen on Planar Anisotropy of the r -value

The planar anisotropy of the r-value of duplex stainless steel sheets showed reverse V-type. To ascertain the possibility of control, the anisotropies and textures of cold-rolled and annealed sheets with different amounts of nitrogen, based on 21.2%Cr-1.5%Ni-5.0%Mn-0.02%C steel, and for different annealing temperatures after hot rolling were investigated.
