Introduction
The work of the group is directed to an explanation of basic mechanisms of high temperature creep in metallic materials, relations between creep behaviour and microstructure and to a transfer of obtained results to technical applications. Theoretical investigations consist in modelling of the microstructure processes. Experiments include conventional and non-conventional creep tests and structure investigations. The development of new testing facilities and procedures has resulted in a unique equipment of creep laboratories of the Institute.
Following topics are investigated:
- constitutive description of creep behaviour
- constant structure creep
- creep in modern magnesium alloys and their fibre strengthened composites
- creep in modern dispersion strengthened aluminium alloys and discontinuous metal matrix composites
- creep in magnesium alloys and composites
- application of two phase model of the structure in creep
- mechanisms of creep in metallic materials at very low creep rates
- small punch test method assessment for the determination of the residual creep life of service exposed components (including welds)
- possibilities of small punch testing in investigations of mechanical behaviour of metallic materials
