AEM investigation of ceramic/lncoloy 909 diffusional reactions after joining by HIP
Diffusion bonding by hot isostatic pressing (HIP) was performed between Incoloy 909 and five different ceramics. Two of the ceramics were composites made from powder mixtures of Si3N4 and either 60 vol% TiN or 50...

Precipitation Hardening of Mg-Zn and Mg-Zn-RE alloys
The age-hardening response of two cast Mg-Zn-RE alloys has been investigated and compared with that of a binary Mg-Zn alloy. The microstructures of the aged specimens were examined by analytical electron micro...

The intergranular microstructure of cast Mg-Zn and Mg-Zn-rare earth alloys
The solidification path and microstructure of cast Mg-9Zn and Mg-8Zn-1.5MM (misch metal) alloys have been investigated by a combination of thermal analysis and analytical electron microscopy. The addition of 1...

Age hardening and precipitation in a cast magnesium-rare-earth alloy
The precipitation sequence responsible for the age-hardening behaviour of a cast Mg-1.3 wt% rare-earth alloy has been investigated by analytical electron microscopy. Very fine intermediate precipitates formed ...
