This paper discusses the influence of Particle Stimulated Nucleation (PSN) on the overall process of nucleation and subsequent grain growth in low carbon (LC) steels and proposes a global recrystallisation kinetics model based on fundamental physical metallurgy principles. The model takes into account the cementite content, which is dependent on the nominal carbon content, and the second phase ...

THREE magnificent gifts have been made during the last few months for the furtherance of-research in this country. In May it was announced that Lord Austin had placed a quarter of a million sterling at the disposal of the University of Cambridge to be devoted to the work of the Cavendish Laboratory. More recently still Lord Nuffield has presented to the University of Oxford a million and a quar...

Pavlíková, Department of Environmental Protection in Industry, Faculty of Metallurgy and Materials Engineering, VSB – Technical University of Ostrava, Ostrava, Czech Republic The goal of the article is to present analysis of metallurgical industry contribution to annual average PM10 concentrations in Moravian-Silesian based on means of the air pollution modelling in accord with th...

Ti-Al-Si alloys are prospective material for high-temperature applications. Due to low density, good mechanical properties, and oxidation resistance, these intermetallic alloys can be used in the aerospace and automobile industries. Ti-Al-Si alloys were prepared by powder metallurgy using reactive sintering, milling, and spark plasma sintering. One of the novel SPS techniques is high-pressure s...

This paper describes an instrument capable of detecting flaws in “green-state” (prior to sintering) powder metallurgy (P/M) parts. The instrument uses a matrix of impedance measurements from a multiprobe array that contacts the surface of the P/M part. The array of measured data is processed to not only detect the presence of flaws but determine their location, size, and orientation as well. Ex...

Data regarding bulk polycrystalline nickel samples obtained by powder metallurgy using Spark Plasma Sintering (SPS) are presented, with a special emphasis on the influence of a cold isostatic pre-compaction on the resulting morphologies and subsequent mechanical properties. Three types of initial powders are used, nanometric powders, micrometric powders and a mixture of the formers. For each ty...
