AbstractGrey cast iron has been regarded, in some circles, as being brittle, low in reliability and one where the usual design equations cannot be applied. The reason is usually attributed to the presence of randomly distributed graphite flakes. This presentation discusses, both experimentally and theoretically, the notch strength, bending strength, and the scattering of tensile strength of grey cast iron, and suggests a new approach based on plasticity theory for the accurate evaluation of these characteristics. Experiments showed that grey iron has a very low notch sensitivity in circumferentially notched bars, but that strength decreases in edge-notched plates. At the temperature of liquid nitrogen, notch sensitivity is very high. In ductile iron, strength increases in notched specimens. These results have been interpreted by the stress distribution, taking into account non-elastic stress/strain behaviour, and using a fracture criteria with an over-stressed depth, δ· The δ is a necessary region for fra...

AbstractA new method known as CHAPEL (Continuous Hydrogen Analysis by Pressure Evaluation in Liquids) for measuring hydrogen content in molten aluminium alloys has been developed and tested. The method relies on direct measurement of the hydrogen partial pressure in the melt. A number of interesting potential applications are indicated on the basis of laboratory and industrial experiences. The main advantage of the CHAPEL method, as compared to other techniques, is its ability to provide direct, continuous measurement of hydrogen in the melt, making it particularly suitable for process monitoring of aluminium melt quality. This paper systematically examines the influence of hydrogen content on porosity in aluminium-silicon cast alloys, taking solidification conditions and melt treatment into account. In this system, the greatest susceptibility to porosity is encountered with AlSi7Mg. An influence of the solidification rate on porosity, which varied with different hydrogen contents, was noted. The work des...
