WebSep 15, 2007 · The effect of hot isostatic pressing (HIP) on fatigue properties of A206-T71 castings was investigated. Castings were (i) non-HIPed, or HIPed at (ii) typical HIP temperature, (iii) solution heat-treat temperature and (iv) eutectic melting temperature. HIP conditions were found to increase average and maximum fatigue life. WebDec 1, 2024 · Hot isostatic pressing (HIP) is a heat treatment method that has been historically used to reduce porosity and enhance mechanical properties of cast metals (Brummer et al., 2010). It works by heating the metal to an elevated temperature, whilst applying an isostatic gas pressure.
WebHowever, aluminum castings are susceptible to porosity defects. Porosity is a microscopic void or hole found in a casting. To eliminate micro-porosity defects in aluminum castings, multiple heat treatments can be used. In particular hot isostatic pressing (HIP) can be used to effectively to remove sub-surface porosity in complex shaped castings.
