Method and system for manufacturing of multi-component complex shape parts consisting of monolithic and powder materials working at different performance conditions

The system for manufacturing of the said multi-component parts consisting of monolithic elements from high temperature resistant material and high strength powder material working in different performance conditions and temperature intervals including:

• said monolithic elements made from the material with higher creep resistance compared to the said powder material
• means to control the deformation of the said monolithic elements and the said powder material during densification under hot isostatic pressure in a form of a vacuum tight capsule having the outer shape of the said multi-component part and dimensions accounting deformation during HIP densification of powder
• means or more specifically inserts filling the space between the monolithic elements in the said capsule to control the dimensions and shape of monolithic elements of the said multi-component part so that they provide after HIP deformation final dimensions of the said multi-component part
• powder completely filling the cavity formed in the said capsule with the said monolithic elements assembled with the said inserts and constituting after HIP the powder elements of the said multi-component part.
• means to control the structure and properties of the monolithic elements by solution treatment at high isostatic pressure in order to homogenize their material, to dissolve residual cast eutectic and to provide the micro-structure and the properties insensitive and steady during the subsequent HIP and heat treatment of the powder material.
• means to control the dimensions and shape of the capsule and inserts accounting their deformation during HIP densification of powder and providing the final position of the said monolithic elements in the said multi-component part and final dimensions of the multi-component part
• means to control the shape and position of the said monolithic elements assembled in the capsule together with the said inserts filling the intervals between the monolithic elements.
• means to control filling of the said capsule with powder and the tap density of the said powder accounting their deformation during HIP densification of powder and providing the final position of the said monolithic elements in the said multi-component part and final dimensions of the multi-component part
• means to evacuate, out-gas and seal the said capsule with powder, monolithic elements and inserts so that vacuum better than 1 mtorr is reached inside the capsule and is kept during hot isostatic pressing providing firm bonding of powder with the monolithic elements and full densification of powder to 100% density the said during hot isostatic pressing
• means for hot isostatic pressing of the said sealed capsule with powder, monolithic elements and inserts providing full densification of the said powder to 100% density,
• means to remove the said capsule and said inserts from the said multi-component part after densification providing the final position of the said monolithic elements in the said multi-component part and final dimensions of the multi-component part
• means to control the heat treatment of the powder material providing no surface reaction or geometrical distortion of the said monolithic elements in the said multi-component part.
