Magmasoft casting impeller cracked#

Microfracture observation results showed that eutectic Si particles segregated along cells were cracked first, but that aluminum matrix played a role in blocking crack propagation. All the cast A 356 alloys contained eutectic Si particles mainly segregated along solidification cells, and the distribution of Si particles was modified by squeeze- casting and casting-forging processes. These A 356 alloys were fabricated by casting processes such as rheo- casting, squeeze- casting, and casting-forging, and their mechanical properties and fracture toughness were analyzed in relation with microfracture mechanism study. The present study aims at investigating the effects of eutectic Si particles on mechanical properties and fracture toughness of three A 356 aluminum alloys. Lee, Kyu Hong Lee, Sung Hak Kwon, Yong Nam International Nuclear Information System (INIS) It is suggested that the thixo-forging combined with the low superheat casting process is an effective technique to produce aluminum alloy wheels with high mechanical properties.Д®ffects of Eutectic Si Particles on Mechanical Properties and Fracture Toughness of Cast A 356 Aluminum Alloys The tensile strength, yield strength and elongation of the thixo-forged wheels with T6 heat treatment are 327.6 MPa, 228.3 MPa and 7.8%, respectively, which are higher than those of a cast wheel. When the round billet is reheated at 600 Г§ВЇЕ for 60 min, the non-dendritic grains are changed into spherical ones and the round billet can be easily thixo-forged into wheels. The results show that the A 356 aluminum alloy round billet with fine, uniform and non-dendritic grains can be obtained when the melt is cast at 635 Г§ВЇЕ . The as- cast microstructure, microstructure evolution during reheating and the mechanical properties of thixo-forged wheels made from the A 356 aluminum alloy were studied. Production of A 356 aluminum alloy wheels by thixo-forging combined with a low superheat casting processДirectory of Open Access Journals (Sweden)ДЇull Text Available The A 356 aluminum alloy wheels were produced by thixo-forging combined with a low superheat casting process.

A 356 melt has been subjected to mechanical vibration with the frequency range from 0 to 400Г‚В . Mechanical vibrations were applied to A 356 aluminum alloy through set up. The objective of this investigation was to evaluate the effect of vibrations (during solidification) on the metallurgical properties of A 356 aluminum casting. Our moto is to deliver quality products within stipulated time.Evaluation of microstructure of A 356 aluminum alloy casting.
