Hot Isostatic Pressing meeting attracts large international audience
Around 70 delegates attended and, of these, around two-thirds were from industrial companies rather than academia and these companies spanned HIP equipment and material suppliers, HIP process practitioners/developers and users/potential users of the technology. Particularly impressively for a meeting of this type, around 20% of the delegates had travelled from overseas to attend.
David Whittaker, Materials KTN Technology Expert, was at this meeting organised by the High Temperature Materials and Particulate Engineering committees of the Institute of Materials, Minerals and Mining (IOM3) and co-sponsored by the European Powder Metallurgy Association (EPMA), at The Riverside Centre, Derby on November 16, 2011.
The impressive credentials of HIP (Hot Isostatic Pressing), in terms of current capabilities and future development potential, were emphasised to the delegates in a series of high quality presentations.
The major messages delivered by these presentations were:
- The significant improvements in mechanical, fatigue and creep properties achievable through the elimination of closed porosity by HIP processing of cast or pre-sintered products and direct powder consolidation. These benefits were quantified in several presentations during the day.
- The capability of the process for near net shape manufacture of complex, 3-dimensional forms by direct consolidation of powder feedstocks.
- The current developments in HIP processing equipment, which is allowing ever-increasing size of HIP products and the capability for the combination of forming and heat treatment in the same processing cycle.
- The latest advances in powder materials for HIP consolidation
- The benefits of HIP for creating material variants that could not be achieved conventionally (e.g. the creation of functionally graded structures, HIP-cladding, HIP-diffusion bonding etc.)
- The growing sophistication of process modelling capability in the HIP processing sector.
- Established and novel applications for HIP products in diverse and demanding application sectors e.g. aerospace, fossil fuel power generation, nuclear power generation, oil and gas.
In parallel with the event the EPMA has issued a brochure “Introduction to Hot Isostatic Pressing” available for free download from the EPMA website – www.epma.com/onlinepublications or free hard copies can be obtained by contacting the EPMA Secretariat directly on 0044 (0) 1743 248899.
