The influence of superimposed total strain controlled HCF loadings on TMF life is presented and discussed for several cast Al-Si alloys, the Ni-base superalloy Inconel 617 and the cast iron GJS-700. Except for GJS-700, a threshold of the superimposed

Thermal fatigue (TF) tests were performed on the aluminium alloy EN AW-6061-T6, non-reinforced and reinforced with 15 and 22 vol.% Al2O3 particles, respectively. The MMCs were produced by stir casting followed by hot extrusion. Thermal fatigue tests

For the production of small quantities of micro devices, machining is a low cost alternative to lithographic processing techniques. However, machining shows process specific size-effects upon miniaturization to the micrometer regime. Hence, the ortho

Tools for hot wire rolling are exposed to high thermal, mechanical and tribological loadings during service. Ceramic materials such as silicon nitride possess good mechanical and tribological properties up to temperatures where most of today' roller

Dynamic strain ageing processes may increase the fatigue limit of steels. To activate these processes, thermomechanical treatments with cyclic loadings at the temperature of the highest effectiveness of dynamic strain ageing can be applied. The treat

Tensile test micro specimens (gauge section 780 x 260 x 130 μm 3 ) made of aluminum bronze were produced by vacuum pressure casting. Two semicircular notches of radii ranging between 5 and 45 μm were located in the middle of the gauge length. These
