  • Patent number: 11969789
    Abstract: A method of determining the condition of a metal powder for use in an additive manufacturing process, involving processing an image of the powder to measure a surface property of the powder, such as colour, texture or particle shape. The proportion of powder whose measured surface property falls outside a pre-determined range is determined and can be used to decide whether or not the powder is suitable for re-use. The proportion is determined by identifying individual particles in the image which are identified as statistical outliers amongst all of the particles shown in the image when considering a measured surface property. The relevant proportion may be determined statistically.

  • Patent number: 11969797
    Abstract: A syntactic metal foam composite that is substantially fully dense except for syntactic porosity is formed from a mixture of ceramic microballoons and matrix forming metal. The ceramic microballoons have a uniaxial crush strength and a much higher omniaxial crush strength. The mixture is continuously constrained while it is consolidated. The constraining force is less than the omniaxial crush strength. The substantially fully dense syntactic metal foam composite is then constrained and deformation worked at a substantially constant volume. The deformation working is typically performed at a yield strength that is adjusted by way of selecting a working temperature at which the yield strength is approximately less than the omniaxial crush strength of the included ceramic microballoons. This deformation causes at least work hardening and grain refinement in the matrix metal.
