he demand for more efficient and durable material

solutions is continuously rising in industry. Longer material

life spans combined with energy efficient solutions reduce

environmental load and enhances business potential. The

conventional research and development (R&D) routes in

searching for new material solutions make use of extensive

experimental programs and material characterization,

which often results in a high cost trial and error scenario.

Furthermore, it is quite difficult to ascertain prevailing stress/

strain states and the dynamic nature of failure initiation

and progression. It is therefore challenging to establish

causalities and links between microstructure of a material

and its performance. Optimization of the microstructure

for a certain application requires a considerable joint effort

of material processing and retesting of different solutions.

Integrated computational materials engineering (ICME) offers

one solution to cut down costs and reduce uncertainties of

materials R&D process. Virtual modeling utilized together

with advanced characterization and experimental work allows

designing microstructures more effectively and understanding

the prevailing phenomena more easily. Multi-scale modeling

makes it possible to couple macroscopic application scale with

a large amount of concurrent physical phenomena and fine

scale microstructure level with detailed individual phenomena,

which enables performance driven virtual design on material

solutions. In the present work, we demonstrate ICME based

approach on developing advanced steels and coatings for

industrial applications. For example, tribological contacts are

examined at different length and time scales. Microstructure

based models are employed to reveal microscale deformation

behavior and failure mechanisms. For advanced steels

including martensitic and high manganese austenitic steels,

high stress abrasive conditions are analyzed at macroscopic

and microscopic scales. Crystal plasticity models are used

to describe micromechanics and evaluate the performance

of different virtually designed microstructure alternatives.

Coatings are studied in terms of coating structures and

topographical features to evaluate the damage mechanisms,

tolerances and ultimately tendency to fatal cracking. The

effect of coating microstructural features and properties are

discussed from the wear resistance point of view.
