Thermal expansion characteristics of AX41 magnesium alloy reinforced by 12 vol.% of short Saffil fibers were investigated at the temperature range of 25–380 °C. Specimens cut at various angles involving random planar distribution of fibers were us

The main aim of the experimental work described is the comparison of the results of the conventional creep tests with those of small punch creep tests, i.e. of miniaturized disc bending tests performed on 14 MoV 6 3 and X20 CrMoV 12 1 steels, respect

Creep behaviour of long range ordered β ′-brass was investigated with the aim of obtaining more information exploitable in an explanation of the physical basis of creep taking place in the ordered structure of metallic materials. In addition to co

Constant structure creep experiments in the primary creep stage of several metallic materials were realized using the technique of sudden applied stress changes. The results were interpreted by means of the back stress concept. In a FeSi alloy the

Constant structure creep in several metals and alloys was investigated in structures corresponding to the steady state creep conditions. Results were interpreted by means of the back stress concept. In accord with postulates of the strain transient d

The creep behavior of low-alloy steel was studied using small punch tests under the action of constant force. Disks with a diameter of 8 mm and a thickness of 0.5 mm were pushed against a die with a bore of 4 mm diameter using a ball of 2.5 mm diamet

The effect of different levels of cold prestrain on some creep characteristics at 975 K of an Fe–21Cr–32Ni alloy was investigated. The prestrain influences the steady-state creep rate, the structure, and the internal stress measured by the strain

On the basis of analysis of the forward creep rate measured immediately after applied stress reductions in the course of steady state creep in zinc, the possibility to explain the thermally activated mechanism of glide is discussed. As the most proba

The precipitation of intragranular M23C6 particles in 21Cr32Ni steel during high temperature creep was investigated using transmission electron microscopy. The strengthening effect of the particles was estimated and the results were compared with
