Making Cast Piece Using Exothermic Head
Journal Title: Analele Universitatii "Dunarea de Jos" din Galati. Fascicula IX, Metalurgie si Stiinta Materialelor - Year 2009, Vol 32, Issue 1
Abstract
In this paper presents a study about cost of part obtained with exothermal heads by replacement of classic heads. This method contributes to conduct solidification of cost pieces, because exothermal heads are forecast witch mixture cover witch at connection with liquid alloys gives off warmth, effect of exothermal reactions between these components.

Intermetalic Copper Phase Characteristics and Links with the Gold Sphere in Alumina Cover Sheets
The time period in which the intermetalic sheet cover is developed into the gold sphere in alumina is fully known being relatively not much literature regarding the morphology ant intermetalic phases growth in the copper...
Degradation of Ceramic Materials in Thermotechnical Plants
It is demonstrated that the degradation of materials is currently a poorly studied scientific area. We propose a definition of degradation and a classification of the types of degradation. It is investigated, using a tec...
