Mechanical Properties and Dimensional Stability Obtained with Different Alloying Techniques

PM2000, in Kyoto, Japan. Author: Mats Larsson. Alloying elements can be added in different ways to metal powders. Admixed, with or without addition of binder, pre-alloyed and diffusion bonded alloying elements are commonly used in the industry. The way of adding the alloying elements influences mechanical properties of the material. Dimensional scatter after sintering is another important characteristic of the material that is influenced. Good dimensional stability after sintering is a way to avoid the need for secondary operations such as sizing and machining. In this presentation, properties of materials with similar alloying content but utilizing different alloying techniques are presented. Both mechanical properties and dimensional stability are investigated and discussed.
