Abstract

A study is reported of the changes in the mechanical properties of chemically vapour deposited ZnS produced as a result of subsequent hot isostatic pressing. Particular emphasis is placed on the microstructural modification produced and the enhancement of fracture toughness achieved. An assessment of the resistance of the material to water jet impact has also been carried out demonstrating a slight improvement in the threshold velocity for damage in the HIPped material. The results are discussed with reference to crack extension theory.
