Properties recovery

Normal reheat treatment can partially restore blade properties however, it does not appear to be capable of full property recovery, although the miscrostructures are comparable to new blades. This shortcoming implies that cavitation may be present and was not removed by conventional reheat treatment. Hot isostatic press (HIP) processing is an alternative that ensures void removal. It has demonstrated its ability to remove even gross internal shrinkage porosity in investment castings. The results of HIP treatment... 

Soda glass Segregation into colour. Removal of closures (metal). Removal of labels. Removal of more toxic contents Options wash cullet add scrubbing towers to melters. High temperatures, process burns off virtually all impurities (into the atmosphere). Hygienic process. No known deterioration of properties. Recovery value 40-50 per... 

Some companies, like Mann Organization in the UK, aim at matching not only at the type, but even an engineering grade performance. It has been found that engineering blends, from housings of the electronic equipment, are the most suitable for the total properties recovery. 

The residual value, ATT esiduai, in practice represents the efficiency of the annealing process. This value depends on annealing temperature and annealing time (holding at annealing temperature). Most experimental results have shown that an annealing temperature between 430 and 475 °C is sufficient for substantially efficient recovery of initial properties. Recovery time for efficient recovery was determined as a minimum of 100 hours.
