It is shown that the main modifiers of foundry magnesium alloys cannot create heterogeneous crystallization centers in melts during their solidification. Modification alloy structures an adsorption‑nanostructural process. adsorbed hydrogen a modifying element alloys. The mechanism modification consists large decrease concentration by significantly reducing dissolved hydrogen.

Similarities and differences between photonic and microelectronic integration technology are discussed and a vision of the development of InP-based photonic integration in the coming decade is given. 1 Photonic integration: introduction After its emergence at the end of the 60s [1], it was believed that photonic integration would take a similar development path to that followed by microelectron...

In this paper, we introduce the production of ductile iron crankshaft of the engine status quo and development. Ductile iron crankshaft discussed smelting process, alloying and manufacturing process mode. This paper focuses on the application of isothermal hardened spheroidal graphite cast iron in the crankshaft, especially its application in the power of the engine crankshaft. We also introduc...
