Investigation of hot iostatic pressing of metal powder to near net shape

• Shape control during HIP is influenced by many variables such as container properties, powder filling method, initial density, temperature and pressure cycle, etc. Experiments have been performed using ASP30 aimed at the study of how to produce parts near net shape through the optimization of these variables. Special care was given to the powder filling and laser welded sheet metal containers of special geometry was used. The results indicate that the temperature and pressure cycles during the first stages of the HIP-process have a pronounced effect on the final shape. A HIP-cycle which will result in a close shape is also presented. Graphs
