Abstract

Hot isostatic pressing (HIP) is an established process for compacting powder metallurgical materials. The numerical analysis of HIP of metal powder requires accurate material models of the technologically applied powder materials. In or- der to show correct behaviour, the constitutive models have to be based on pro- per experimental procedures. Investigation of the transient densification behaviour of a martensitic stainless steel powder during the HIP process and de- velopment of a tool for determination of material parameters of the related con- stitutive model has been employed. The work concludes the usefullness of optimization methods combined with HIP dilatometry in fitting of material para- meters
