Recrystallization and Grain Growth Behavior in Severe Cold-rolling Deformed SUS316L Steel under Anisothermal Annealing Condition

Abstract

, in the equation is calculated and is found to follow the equation PϭK · exp(0.5/q). Meanwhile, the grain growth exponent, n, for the anisothermally annealed SUS316L steel is also determined and is found to lie between 2.5 and 3.0. On the other hand, EBSD analysis of the evolved microstructure at different heating rates indicates that low heating rate caused partial recrystallization with preferred orientations at the recrystallization finish temperature, while high heating rates above 1 K/s induced the homogeneously nucleated recrystallization microstructure with random orientations and a lognormal type grain size distribution.

A Calorimetric Study of Recovery and Recrystallization in Fe–14.4 Cr–15.4 Ni–2.4 Mo–2.36 Mn–0.25 Ti–0.04 C–0.05 P (mass %) Austenitic Stainless Steel

“…The average microhardness values are found to be 455 and 521 VHN, respectively for 70 and 85% coldwork conditions. These measured hardness values are in good agreement with the reported ones for coldworked 316 and 316‐Ti added austenitic steels . On the other hand, the 1323 K/15 min.…”

“…In some parts of microstructure, the presence of macro deformation bands (arrow #3) and numerous crisscrossing slip traces (arrow #4) are also noticed. In general the deformed microstructure appears to be inhomogeneous, as is already observed by others on severely deformed austenitic stainless steels …”

The effects of heat treatment on the mechanical properties of cold-sprayed coatings

“…11(c)). Recrystallization temperature of stainless steel 316 in the present studies seems to be a little higher than Hirota's research (from 800 to 950°C) [26]. It is possible that the porosity in the stainless steel coating has obstructed its diffusion between the particle interfaces during heat treatment and made the recrystallization temperature become a little higher.…”

Influence of Cold Rolling on Diffusion Bondability of SUS316L Stainless Steel Sheets

“…As the microstructure of sheets can be markedly changed by final treatment, such as cold rolling, 18) it is necessary to study the diffusion bondability of cold rolled sheets. Indeed, the bonding temperature of sheets is known to vary between lots and something unknown parameters.…”
