Web2 days ago · When the inclusion is dirt, castings will have a honeycomb or spongy look. Hot Tears. Hot tears, also known as hot cracks, show up when the cooling metal contracts. In this state, when the metal is still weak, residual stress in the metal or poor mold design can cause the metal to pull apart, resulting in branching, irregular cracks. Sometimes ...
WebMay 31, 2012 · Depending on the source, from which non-metallic inclusion are derived, they are subdivided into two groups: indigenous and exogenous inclusions. Indigenous inclusions are formed in liquid, solidified or solid steel as a result of chemical reactions ( deoxidation , desulfurization ) between the elments dissolved in steel. WebAn inclusion is a metal contamination of dross, if solid, or slag, if liquid. These usually are impurities in the pour metal (generally oxides, less frequently nitrides, carbides, or …
WebIn spite of this desirable characteristic, common practice in the magnet wire industry is to limit the area reduction during drawing to about 90%, followed by an anneal. Beyond that level of reduction, metallurgical structure changes can occur which can degrade the wire's mechanical properties.
