Patent Searching and Data


Title:
A METHOD FOR FACILITATING THERMOMECHANICAL FORMING PROCESS OF AUSTENITE CONTAINING GRADES TO PRODUCE TAILORED STRENGTH STRUCTURAL COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2019/028155
Kind Code:
A8
Abstract:
A method to quantitatively determine the amount of deformation induced martensite as a function of temperature and strain in austenitic stainless steels is used to customize the strength and elongation characteristics of certain portions of a formed structural component. Predicting the martensitic volume fraction in a specific part location permits design of particular components with customized strength characteristics that can be consistently repeatably manufactured.
