Low-cycle fatigue property of superalloy GH4586 was investigated using a stress amplitude-controlled mode at 1023K. Fracture surface was examined with a scanning electronic microscopy. It was found that the cyclic life can be illustrated by Manson-Coffin at all s...
The modes of crack initiation and propagation of low cycle fatigue at high temperature were studied on HA-188 cobalt base alloy by means of scanning electron microscopy. Low cycle fatigue tests were carried out at 700℃ in the strain rate range of 3 x 10^ to 2 x l0^sec^. In the high...
The fracture surface of the fatigue specimens was studied using scanning electron microscopy. It was found that fatigue crack initiation is transgranular, however, fatigue crack growth exhibits a strong dependence on temperature. The cyclic deformation process, creep and oxidation are thought to be the...

This paper describes the preliminary study on the evolution of the surface roughness in polycrystalline 316L austenitic stainless steel during low-cycle fatigue using an optical interferometric surface profiling technique. The arithmetic mean surface roughness of four regions with different stress levels was...
Quantitative analysis of fatigue behavior, fatigue damage and fatigue fracture surfaces of low carbon bainitic steel (SAE 15B13). Quantitative analysis of fatigue behavior, fatigue damage and fatigue fracture surfaces of low carbon bainitic steel (SAE 15B13)... ...
However, a mixed morphology of ductile and cleavagelike fracture was observed on the fracture surface of the subsize specimen in which the grain structure appeared to have undergone a change because of the presence of surface cold work. The braze has superior fatigue resistance, but to exploit ...
