Strain-Induced Martensite Transformation Simulations during Cold Rolling of AISI 301 Austenitic Stainless Steel
Austenite is a semi-stable phase in most stainless steels that deforms to martensite under Md30 and forms martensitetype ά and ε due to the deformation in the steels. Since the distribution of strain induced martensite plays animportant role in achieving desired properties, the main objective of the present work is to model martensitedistribution of ά during cold rolling using...
متن کاملDesign optimization of cutting parameters for turning of AISI 304 austenitic stainless steel using Taguchi method
In the present work Taguchi method is used to optimize cutting parameters during dry turning of AISI 304 austenitic stainless steel with AlTiCrN coated tool. The coating was deposited on fine-grained K-grade (ISO K-20) cemented carbide cutting insert using physical vapor deposition (PVD) technique. The turning parameters evaluated are cutting speed of 200 and 260 m/min, feed rate of 0.20 and 0....
متن کاملGrain Size Effect on the Hot Deformation Processing Map of AISI 304 Austenitic Stainless Steel
In this study, the hot deformation processing map of AISI 304 austenitic stainless steel in two initial grain sizes of 15 and 40 μm was investigated. For this purpose, cylindrical samples were used in the hot compression test at the temperature range of 950-1100 °C and the strain rate of 0.005-0.5% s-1. At first, the relationship between the peak stress and Zener-Hollomon parameter w...

متن کاملMartensite ? austenite phase transformation kinetics in an ultrafine-grained metastable austenitic stainless steel
A generalized phase transformation kinetics model is used to understand the martensite to austenite transformation in a cold-rolled and annealed metastable AISI 301LN ultrafine-grained austenitic stainless steel. The model shows that the presence of interstitial nitrogen and heavy cold-rolling is important to promote fast transformation kinetics, through rapid nitrogen-diffusion and austenite n...
