Technical Publication No. 2313 Class E, Metals Technology, January 1948 DISCUSSION OF THIS PAPER IS INVITED. It should preferably be presented by the contrihutqr in person at the New York Meeting. February 1948. when an abstract of the paper will be read. If this is imposs~ble, discussion in writing (a copies) may be sent to the Secretary. American Institute of Mining and Metallurgical Engrneer...
D. Malindžák, BERG Faculty, Technical University of Košice, Košice, Slovakia Metallurgical production processes (MPP) consist of continuous and discrete types of technology operation, transport, manipulation and storing processes regards the fl ow of material and also the equipment and machines. Other specifi cs are: long production cycles, great inertia, tree structure of production processes ...
Simulation of metallurgical processes has been the subject of intense research due to the reduced number of experiments required for controlling the process as well as time and energy savings it allows. In gas carburizing of steel parts, the amount of carbon at the surface of carburized parts is the most important specification of the process in terms of achieving the desired metallurgica...
Casting represents a production process where liquid material is poured into mold with hollow cavity, usually of the intended shape, following which its solidification allowed. Numerous defect types are available, including blow holes, pin burrs, defects, shrinkage metallurgical casting metal etc. All industries have quality control departments to eliminate occurrence this defective product. Bu...
ALADIN is an expert system that aids metallurgists in the design of new aluminum alloys. The project began in January 1984, and two major iterations of the system design have been completed. The current system is a hybrid of several approaches and artificial intelligence techniques. Declarative representations are used for metallurgical data and concepts. The basic design procedure is encoded i...
Chromite ores are basically classified on basis of Cr2O3 content and Cr to Fe ratio in a sample. The higher content of Cr increases the value of the ore but this is greatly affected by the presence of impurities in form of silicates, oxides or hydroxides. The present study was performed to analyze the impurities of chromite ore collected from Prangghar (Mohmand agency), Pakistan. From x-ray dif...
Differences in mechanical properties between endodontic instruments might be related to the chemical composition, phase constitution, or fabrication process of nickel–titanium (NiTi) endodontic instruments. An awareness and knowledge of the mechanical properties of NiTi endodontic files and their association with the metallurgical properties is useful for clinicians to understand the behavior o...
The Cu-Sn metallurgical soldering reaction in two-segmented Cu-Sn nanowires is studied by in situ transmission electron microscopy. By varying the relative lengths of Cu and Sn segments, we show that the metallurgical reaction results in a Cu-Sn solid solution for small Sn/Cu length ratio while Cu-Sn intermetallic compounds (IMCs) for larger Sn/Cu length ratios. Upon heating the nanowires to ∼5...
Manufacturing of aero-engine components has been improvised over the years, commensurate with technological developments in the aeronautics sector. Compressor blade plays a vital role in an aircraft engine and flaws in its production can have adverse impacts on the performance of an aero engine. Despite technological advancements, many defects arise in these single crystal blades, which are man...
