In this work we report a study of the induced changes in structure and corrosion behavior of martensitic stainless steels nitrided by plasma immersion ion implantation (PI3) at different previous heat treatments. The samples were characterized by x-ray diffraction and glancing angle x-ray diffraction, scanning electron microscopy, energy dispersive x-ray spectroscopy, and potentiodynamic measurements. Depending on the proportion of retained austenite in the unimplanted material, different phase transformations are obtained at lower and intermediate temperatures of nitrogen implantation. At higher temperatures, the great mobility of the chromium yields CrN segregations like spots in random distribution, and the a' -martensite is …

Continued growth and consolidation of the livestock industry such as dairy industry has generated large-quantities and high-strength manure, which has long been identified as a major contributor to diffuse source pollution in Australia. However, conventional dairy shed wastewater treatment practices in Australia such as two pond systems still do not provide sufficient treatment. In addition, relevant laws and regulations in terms of nutrient management plans and manure solids disposal require new waste management approaches. Anaerobic digestion (AD) is an efficient, small footprint, cost effective and sustainable technology that should be applied in Australian dairy farms, and has the potential not …

Driven by stricter environmental regulations and legalisation on wastewater discharge and shrinking fresh water resources, water treatment has become an area of significant concern while at the same time there is a growing interest in utilising non-traditional water resources by means of water reclamation and water recycling.

Linear elastic fracture mechanics was used to optimise the vacuum-heat-treatment procedures for conventional hot-work AISIHII tool steel. The fracture toughness was determined with non-standard, circumferetially notched and fatigue-precracked tensile-test specimens.
