Abstract

The regularities of the process of hard and soft wood pressing are studied in the paper, with the purpose of determining the possibility of using wood as a wrapper for dry isostatic pressing, as it meets the basic wrapper requirements. The advantage of this material is a sufficiently low cost, lack of iron powder adhesion and easy removal after pressing. It is shown that the use of soft wood as the wrapper material allows to obtain products from iron powder mixtures with high density and strength. It is found that the use of additional heat treatment improves the wood pressing, as well as the absence of pressing friction on the matrix walls improves the iron powder compaction. The results of the conducted studies can be used in creating powder products of complex shape, which operate under medium and heavy loads.
