“Hydrogen embrittlement of steels is one of the main challenges to overcome to achieve the widespread deployment of the hydrogen economy”
With the ICME methodology, developed by TECNALIA, new predictive models are created to address the challenges when designing new metallic materials
One of the lines TECNALIA is working on is the development of solidification models: these predict the microstructural evolution of the material in advanced aluminium alloys and in processes such as additive manufacturing.
TECNALIA continues to work on models that analyse how hydrogen diffusion occurs in steels, and the aim is to reduce embrittlement.
Hydrogen embrittlement of steel
Hydrogen embrittlement of steel is one of the main challenges to overcome in order to achieve the widespread implementation of the hydrogen economy.
The ICME methodology addresses the complex interactions between the chemical composition of the material and the characteristics of its manufacturing process; with the resulting microstructure; with the material properties corresponding to that microstructure; and with its performance.
This methodology therefore responds to the needs to develop new metallic materials capable of withstanding much more extreme operating and/or manufacturing conditions, due to the emergence of disruptive applications and radically innovative manufacturing processes.
Latest developments in two types of predictive models
Our colleague Ane Jiménez presented the latest advances in these two types of predictive models at the 7th World Congress on Integrated Computational Materials Engineering (ICME 2023) held in Orlando, organised by TMS, USA.
This congress is the leading international forum on the ICME theme: a meeting point for scientists and engineers involved in the development of new materials and simulation models. TECNALIA presented its developments in this field to important companies such as NASA, Boeing, Rolls-Royce, General Motors, General Electric, Siemens, Tata Steel, PCC Metals, Novelis, QuesTek, Dassault Systemes, etc., and exchanged knowledge with numerous prestigious universities and research centres from all around the world.
