Abstract：The paper reviews a decade of progress in high temperature mechanical behavior of materials and structures. The highlighted topics are multiscaling of mechanical behavior of materials at high temperature, creep mechanics of multi- component materials system, high temperature fracture under constraint and safety assessment of high temperature components. To meet the future challenges of the safe operation of high temperature plants and the development of high-tech machines, more efforts should be taken to address some critical issues, which includes correlation and transformation of the events in temporal and spatial scales: to understand the physico-chemical kinetics and the influence of external stresses; the measurement and theoretical interpretation of interfacial strength and defects at high temperature; the development of high temperature theory that takes into account the constraint effect on the stress field ahead of crack tip and creep crack growth rate; the extension of the current failure assessment diagram to cover the complexity of damage mechanisms by introducing a time-dependent damage scale.
