“…Previous studies reported that after the hot and the cold rolling process stainless steel showed preferential crystallographic textures [2][3][4][5][6][7][8] . In particular, Raabe and Lücke, 4 showed that ferritic steels, non-stabilised or stabilised with Nb or Ti, had a texture gradient through the thickness of the samples.…”

The objective of this work is to investigate the influence of the crystallographic texture on the corrosion resistance of 16% Cr ferritic stainless steel. Samples of ASTM S43000 ferritic stainless steel, both niobium-stabilised and non-stabilised, were used. The samples were subjected to crystallographic characterisation (EBSD) and analysed using an inverse pole figure (IPF) and a crystalline orientation distribution function (CODF). The samples also underwent anodic potentiodynamic polarisation tests (deaeration by high-purity argon gas) in 3.56% NaCl and 1N H 2 SO 4 solutions, and the surface was examined by SEM after the tests. The results showed a clear influence of the crystallographic texture on the corrosion resistance. The niobium decreases the amount of the preferred orientation and thus the influence of the texture on the corrosion resistance, although the corrosion resistance of the stainless steel is increased as niobium carbides are formed.

“…For austenite, they were similar to those previously identified after warm-rolling. It is well known that the texture of both austenite and strain-induced martensite evolves during deformation 31,33,34,38,39) leading to partially transformed austenitic steels and that the thermomechanical treatment leads to a well defined texture observed in both austenite and aЈ-martensite phases as reported in the literature. 10,36,40) Following the Kurdjumov-Sachs (K-S) relationships, the four most intense fcc deformation components {112}͗111͘ g copper, {110}͗112͘ g B, {123}͗634͘ g S and {110}͗001͘ g G are expected to transform into {112}͗110͘ aЈ , {001}͗110͘ aЈ , {211}͗113͘ aЈ and {112}͗110͘ aЈ bcc texture components.…”

The effect of the aЈ-strain induced martensite on the austenitic stainless steel grain size reduction is analyzed. Rolling with a 80 % reduction factor at 200°C and at 20°C resulted respectively in a heavily deformed austenite and a mixed deformed austenite with aЈ-martensite bands. Further annealing treatments were carried out in the range of 20-880°C. Fine grains of about 1 mm can be obtained in the metastable austenitic stainless steel by a repetitive cold rolling and annealing thermomechanical process. In this case, reversion mechanism from deformation induced martensite aЈ to austenite g is responsible for grain refining. Nonconventional warm rolling and annealing process can also lead to fine grains of 2 mm without a reversion stage and as a result of recrystallization process of the strain-hardened austenite. The cold rolling route gives rise to a bimodal grain size distribution with a "lamellar" structure resembling to a "composite" material.

“…In SUS 304 stainless steel, martensite is introduced in the phase matrix by cold-working. 15) As has been shown in Fig. 2, a variation of martensite content with the amount of cold work (thickness reduction by rolling) measured by X-ray analysis of the annealed, 5%CW and 25% CW SUS 304, and the contents are about 0%, 5% and 77%, respectively.…”

“…Moreover, distribution of the introduced dislocations in SUS 304 was not uniform but localized and tangled in the vicinity of martensite boundaries as has been indicated in the previous report. 15) Therefore, Mansur's model, which assumes evenly distributed network dislocations, cannot be applied directly to the cold-worked SUS 304 as will be discussed in the following.…”

SUS 304 stainless steel has been used in the light-water reactors constructed in earlier days, in which irradiationassisted stress corrosion cracking has drawn increasing attention and tensile residual stress is believed to be one of the major causes. It is, therefore, essential to assess its stress relaxation behavior under irradiation, which can be evaluated from the irradiation creep data, and the effect of cold work on it. Creep experiments under 17 MeV proton irradiation (2Â10 À7 dpa/s) at 288 C were conducted for SUS 304 with 5% and 25% cold work (CW). Irradiation creep rate of 5%CW was only slightly larger than that of 25%CW. Stress dependence was almost quadratic in both specimens, in contrast with the linear dependence in cold-worked SUS 316L reported earlier. Stress relaxation under irradiation was found to reflect this quadratic dependence. Martensite is induced by cold-working in SUS 304, not in SUS 316L, and marked difference in its amount was found between 5%CW and 25%CW, despite the small difference in irradiation creep behavior. Thus, the observed quadratic dependence appears to result not directly from the induced martensite itself but from a climb-enabled glide of the tangled dislocations densely formed in the vicinity of martensite phase boundaries.
