Cercetări privind deformarea plastică a fontelor
(Universitatea "Dunărea de Jos" din Galați, 2003)Fonta, este un aliaj al fierului cu carbonul, cu bune proprietăți tehnologice, mecanice și chimice, și a atras atenția oamenilor din cele mai vechi timpuri (cele mai vechi semnalări sunt din 600 î.e.n., în China) și până ... -
Considerations Upon Breaking Strength of Nodular Cast Iron Under Plastic Deformation
(Universitatea "Dunărea de Jos" din Galați, 2002)The work aims to demonstrate the existence of a mathematics connection between breaking strength and degree of plastic deformation in case of nodular cast iron. Research made along time starting 1932-1934 until now, ... -
Estimation of the Metallurgical Industry Impact on the Environment
(Universitatea "Dunărea de Jos" din Galați, 2005)Objectively, the ecosystem in its development and working implies the accumulations on of some nonconcordances. Summing these disfunctions without taking into consideration their attenuation, may lead to producing, achieving ... -
