Acoutic emission shows promise for monitoring MMC process

Research output: Contribution to specialist publicationArticle


Acoustic emission is emerging as a promising technique for monitoring the squeeze casting process used in metal matrix composite (MMC) production. The monitoring process is being developed to ensure complete infiltration has occurred during squeeze casting. A research team at Pennsylvania State University, has studied acoustic emission monitoring using a high silicon aluminium alloy and a fibre preform produced from alumina silicate fibres. The group identified and characterized the various types of acoustic emission that could arise during the process, including metal solidification noise, preform crushing noise, as well as background and machine noise that had to be filtered out.
