High-pressure die-cast (HPDC) aluminum alloys cannot normally be heated to high temperatures due to the presence of pores containing entrapped gases, which lead to the formation of surface blisters. CSIRO Materials Science and Engineering (Melbourne, Australia; edlinks.che.com/7371-548) has found that blistering can be avoided by using shorter solution-treatment times at lower temperatures. CSIRO says its...

A new process to produce titanium, called the TiRO process, has been developed by a team from CSIRO (Melbourne, Australia; edlinks.che.com/6901-538) through its Light Metals Flagship. The process is said to halve the cost of producing titanium metal components by: 1) Replacing the conventional Kroll-batch process with a more continuous process based on fluidized-bed (FB) technology; and 2) Using Ti’s...

An innovative design of a pulsed-electric-field (PEF) treatment unit for the inactivation of Escherichia coli bacteria has been developed by associate professor Mohammed Farid and Sally Alkhafaji at the Chemical and Materials Engineering Department of the School of Engineering, the University of Auckland, New Zealand; edlinks.che.com/6519-542). The system includes multipass PEF treatment chambers that were...
