abstract: friction stir welding, a solid state innovative joining technique, is widely being used for joining aluminium alloys for aerospace, marine automotive and many other applications of commercial importance. fsw trials were carried out using a vertical machining centre (vmc) on aa6061 alloy. the main objective of the present work was to evaluate the weld processing parameter of friction s...

The mechanical characterization of short E- glass fiber reinforced, graphite and sintered bronze filled epoxy composite was carried out in this study. The aim of the present study was to develop tribological engineering material. In this study the flexural strength, theoretical and experimental density, Hardness and Impact strength of composites was investigated experimentally. The results show...

The ability of laser-ultrasound to monitor in real-time metallurgical transformations is reviewed in this paper. Although the technique is appropriate for online industrial materials characterization, this paper addresses laboratory characterization of metallurgical transformations. Examples are presented on the real-time sensing of grain size and grain growth, phase transformation and recrysta...

The presented article reviews the first experiences with the xenon plasma focused ion beam (FIB) in the scanning electron microscope (SEM) applied on the investigations of shape memory alloys (SMAs). The SMA are the focus of investigation in our department for many years and these investigated alloys are examples of material prepared by novel spark plasma sintering method (NiTi) and traditional...

Abstract: A lot of progress is made in the last decade concerning the theoretical and practical aspects of eddy current testing. In addition to the defect characterization, actual studies deal with the metallurgical evaluation of materials. Surface examination allows the prediction of the material strength and consequently its life time. In order to obtain various microstructures and to modify ...

With the development of ubiquitous information environment in metallurgical industry, driving type of metallurgical equipment systems is changing from energy-driven to information-driven. The problems of the metallurgical equipment information communication path intelligent planning are taken as the research object. Based on the cellular automata theory, the integrated framework of metallurgica...
