PM World's Largest Close-Coupled Gas Atomizer A specialist minerals processing company has placed an order worth f450 000 with PSI Ltd of Polegate, UK, for a production scale atomizer for rapid solidification processing. The 50 kg atomizer, claimed to be the largest close-coupled gas atomizer in the world, is due to be commissioned in North America early in 1991 and is expected to enable an annual production in excess of 100 tonnes. In 1987 PSI introduced its laboratory scale Hermiga range of resistance heated or induction heated atomizers capable of atomizing 10 kg batches. The 50 kg machine is a scaled up version and produces fine powder of the same high quality, says PSI. Thermal Processing Challenges Custom engineered thermal systems where vacuum or reactive atmospheres are an integral part of production processes are discussed in a brochure called 'Teamwork to meet today's thermal processing challenges' published by the Special Engineering unit of the Abar Ipsen Group, of Feasterville, Pennsylvania, USA. The brochure describes the unit's role in developing custom engineered, full scale production thermal processing systems for: improved quality and production, the commercialization of new processes and technologies, the development and enhancement of environmentally safe processes, and total systems integration and control.

Heat Treatment for Reactive Materials A publication from Leybold AG of Hanau, Germany, explains the advantages of conducting heat treatment in a vacuum and specific benefits claimed to arise from use of its IWQ-series of heated quartz tube furnaces.

Benefits include quartz's high resistance to chemical attack, the reliability of the induction coil arrangement, the versatility from the modular design and the ease of operation. The IWQ-series furnaces are suitable for heat treating common metals and their alloys, hardmetals, magnetic materials, metal oxides, metal carbides, ceramics, and even fused silica. Pressures as low as 2 x 10E-5 mbar can be reached. For a copy of the publication (No. 33-150.21) contact Leybold AG, Dept. ZV3, PO Box 1555, D- 6450 Hanau 1, Germany. Economical PM Forged Parts Production A process involving impact forging of sintered preforms is claimed to result in economical production of powder metal (PM) forged parts with properties at least equivalent to parts made by conventional ingot metallurgy technology.
