that go into solid solution impose lattice strains on surrounding host atoms Lattice strain field interactions between dislocations and impurity atoms result in restriction of dislocation movement This is one of the most powerful reasons to make alloys‚ which have higher strength than pure metals. Small impurity atoms exert tensile strains (see figure below) Large impurity atoms exert compressive strains Solute atoms tend to

The graduations are oversized by a proportionate amount‚ for example‚ when constructing a pattern for aluminium alloys‚ the pattern maker uses a contraction rule

In this article the influence of the important resistance spot welding process parameters on the shear-tensile strength of the welded joints of Inconel alloy 625 was investigated. Experimental study using full factorial design of the welding current‚ welding time‚ and electrode force parameters was conducted. In order to identify the influence of each parameter and their interaction a general linear model and a second order model using response surface method was developed. Nonlinear correlation

the subject can now be studied under the following headings : a) Physical metallurgy b) Extraction metallurgy c) Process metallurgy In the recent years studying the metallurgy science gave to humanity an ever growing range of useful alloys. Whilst many of these alloys are put to purposes of destruction‚ we must not forget that others have contributed to the material progress of mankind and to his domestic comfort. This understanding of the materials resources and nature enable the engineers to select

Production and applications Titanium and titanium alloys powders Titanium possesses an exclusive combination of low density‚ good mechanical properties at room and elevated temperatures and good corrosion resistance. Titanium and its alloys are used extensively in aerospace‚biomedical industries and in other industrial applications. However‚ titanium ingots are expensive to produce and fabricate. Another problem is connected with segregation in highly alloyed titanium materials. The high cooling

and brittle compound with chemical formula Fe3C. It has metallic properties. On a base of Fe-Fe3C diagram we can divide iron-carbon alloys into: - steels‚ - cast steels‚ - cast irons. Steel is an alloy of carbon and iron and other alloying elements (e.g. Mn‚ Si) with carbon content up to 2% intended for wrought products or semi products. Cast iron is an alloy of carbon and iron and other alloying elements (e.g. Mn‚ Si) with carbon content over 2% intended for castings. Now‚ we consider
