“…HIP diffusion bonding also has fewer limitations in component geometry and size than conventional diffusion bonding. A variety of components in material combinations of Ni, Co, Ti, or steel alloys have been produced including valve body, well head, flywheel, extrusion dies, grinding roll for corrosion and wear-resistant applications, and turbine blisks [3,[7][8][9][11][12][13]. Feasibility of HIP bonding Ni superalloy and Mo-Re refractory alloy, dissimilar Vanadium alloys, Cu alloy and Ni alloy, stainless steel and Ni alloy, and stainless steel and Ti alloy have been studied at lab-scale [14][15][16][17].…”

This work explores technical feasibility in hot isostatic pressing (HIP) manufacturing of an integral bimetallic component using steel and Ni alloy powder for supercritical carbon dioxide (sCO2) turbomachinery. Lab-scale bimetallic HIP specimens using HAYNES® 282® and SS316L or SS415 powder are investigated in powder configuration, heat treatment, microstructure, and tensile properties up to 400 °C. Interdiffusion profiles at dissimilar alloy interfaces caused by HIP cycle is predicted by DICTRA simulations and validated by electron probe microanalysis (EPMA). The interdiffusion distance of most elements is around 100 μm, while C and N have a higher interdiffusion distance. Dense distribution of Ti-rich carbonitrides and alumina particles are found to decorate prior particle boundaries near joining interface on the 282 side, affecting tensile strength across interface as well as tensile failure location. A higher amount of excessive carbonitride formation near interface is observed in SS316L/282 than in SS415/282, which is consistent with the predicted greater degree of interdiffusion effect in SS316L/282. Typical HAYNES® 282® heat treatment condition is applicable to 282/SS316L and 282/SS415 combinations, resulting in a higher strength than cast CF8M and CA6NM. A pilot-scale bimetallic SS415/282 pipe is then demonstrated to show the promise of scaleup.

Near‐net shaping hot isostatic pressing (NNS‐HIP) forming process has the advantage of high material utilization ratio and good uniformity of billet microstructure. It is widely used to produce critical parts for harsh service environments in special fields such as aerospace and energy and chemical industry. This paper introduces the process characteristics and production flow of hot isostatic near‐net forming, the representative materials of hot isostatic near‐net forming, the development and application at home and abroad, and the micro‐ and macromodels of numerical simulation powder densification by HIP near‐net forming. Finally, the challenges and development trends of this technology are prospected, and corresponding countermeasures are put forward.
