the interfacial compounds and sem Fractography of squeeze cast sicp 6061 al composites
Materials Science and Engineering A-structural Materials Properties Microstructure and Processing, 1996Co-Authors: Boq-kong Hwu, Su-jien Lin, Minten JahnAbstract:Abstract The effects of the addition of silica binder during preform preparation on the development of interfacial compounds in squeeze-cast SiC p /6061 Al composites (containing silicon carbides with particle sizes of 85, 30 and 14 μm) were examined using energy dispersive spectroscopy (EDS) X-ray mapping, scanning electron microscopy (SEM) Fractography and optical microscopy (OM). Various interfacial compounds, Al 2 O 3 , MgO and MgAl 2 O 4 , were observed. The effects of the various interfacial compounds on the SEM Fractography and mechanical properties of the composites were investigated and a mechanism was suggested. The micromechanism of crack initiation, crack propagation and final fracture was discussed using SEM Fractography and OM observations.

application of in situ thermography for evaluating the high cycle and very high cycle fatigue behaviour of cast aluminium alloy alsi7mg t6
Ultrasonics, 2013Co-Authors: Dominik Krewerth, Anja Weidner, Horst BiermannAbstract:The present paper illustrates the application of infrared thermal measurements for the investigation of crack initiation point and crack propagation in the high-cycle and the very high-cycle fatigue range of cast AlSi7Mg alloy (A356). The influence of casting defects, their location, size and amount was studied both by Fractography and thermography. Besides internal and surface fatigue crack initiation as a further crack initiation type multiple fatigue crack initiation was observed via in situ thermography which can be well correlated with the results from Fractography obtained by SEM investigations. In addition, crack propagation was studied by the development of the temperature measured via thermography. Moreover, the frequency influence on high-cycle fatigue behaviour was investigated. The presented results demonstrate well that the combination of Fractography and thermography can give a significant contribution to the knowledge of crack initiation and propagation in the VHCF regime.

Investigation of the Damage Behavior of Cast Steel 42CrMo4 During Ultrasonic Fatigue by Combination of Thermography and Fractography
Advanced Engineering Materials, 2013Co-Authors: Dominik Krewerth, Anja Weidner, Horst BiermannAbstract:The present paper illustrates the application of infrared thermography measurements for the investigation of fatigue behavior of different types of defects in the high-cycle fatigue range of cast steel 42CrMo4 alloy (1.732). The influence of several defects on the fatigue damage behavior was studied by the combination of Fractography and thermography. Different crack initiation times and locations of several defects were detected and evaluated in one specimen. Furthermore, a direct correlation of Fractography and thermography was carried out. The presented results demonstrate well that the combination of Fractography and thermography can give a significant contribution to the knowledge of crack initiation and propagation modes during ultrasonic fatigue of 42CrMo4 steel.
