Material Characterization Solutions for Powder Metallurgy and Additive Manufacturing
New brochure available!
Powder metallurgy is a generic term that covers a range of processes for manufacturing metallic components from metal powders usually by first forming a dimensionally stable compact and then SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. sintering it. The main processes include press and sinter, metal injection molding, hot or cold isostatic pressing and additive manufacturing.
Additive Manufacturing is a relatively new technique that permits local fusing of metal powders using a laser, electron beam, or by post-SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. sintering adhesive bonded powders. There are a number of reasons for using a powder metallurgy process instead of a traditional process such as machining. These include significant cost savings, high dimensional accuracy, a good part to part reproducibility and a reduced waste, just to name a few advantages.
Malvern Panalytical and NETZSCH Analyzing & Testing offer a wide range of material characterization solutions for additive manufacturing.
They help
- ensure a consistent powder supply and prevent variations in product quality
- identify suitable powders for machines with different spreader or rake designs
- optimize atomization conditions to achieve desired powder properties
- predict and optimize powder packing DensityThe mass density is defined as the ratio between mass and volume. density and flow characteristics
- ensure powders have the correct elemental composition and phase structure
- investigate Thermal StabilityA material is thermally stable if it does not decompose under the influence of temperature. One way to determine the thermal stability of a substance is to use a TGA (thermogravimetric analyzer). thermal stability
- characterize debindering and SinteringSintering is a production process for forming a mechanically strong body out of a ceramic or metallic powder. sintering behavior
- optimize melting and CrystallizationCrystallization is the physical process of hardening during the formation and growth of crystals. During this process, heat of crystallization is released.crystallization behavior
- determine Thermal DiffusivityThermal diffusivity (a with the unit mm2/s) is a material-specific property for characterizing unsteady heat conduction. This value describes how quickly a material reacts to a change in temperature.thermal diffusivity/Thermal ConductivityThermal conductivity (λ with the unit W/(m•K)) describes the transport of energy – in the form of heat – through a body of mass as the result of a temperature gradient (see fig. 1). According to the second law of thermodynamics, heat always flows in the direction of the lower temperature.thermal conductivity and Specific Heat Capacity (cp)Heat capacity is a material-specific physical quantity, determined by the amount of heat supplied to specimen, divided by the resulting temperature increase. The specific heat capacity is related to a unit mass of the specimen.specific heat capacity
