تعیین ثابتهای رابطه هال- پچ اصلاح شده و ارتباط خواص مکانیکی با ریزساختار آلیاژ AS7U3G
Mechanical properties of the alloys are a strong function of the average silicon particles size and the secondary dendrite arm spacing (SDAS). Modified Hall-Petch equation expresses the effects of these two microstructural parameters on the yield strength and ultimate tensile strength of the Al-Si based alloys. These microstructural parameters depen on parameters such as chemical composition, c...
متن کاملDENDRITE FRAGMENTATION IN THE SHEARED MELT BY FATIGUE EROSION MECHANISM OF SEMISOLID Al-Si ALLOY (A.356.0
Over the last few decades, there have been many mechanisms proposed to describe the formation of the non-dendritic microstructures during Semisolid Metal (SSM) processing; including dendrite fragmentation, spherical growth, cellular growth and recalescence. Dendrite fragmentation is the most popular mechanism of all these hypotheses. It is the purpose of the present article to examine the morph...
متن کاملHALL-PETCH RELATIONSHIP AND STRAIN RATE SENSITIVITY OF NANOCRYSTALLINE Mg - 5WT% Al ALLOY
This study investigated the grain size dependence of mechanical properties and deformation mechanisms of microcrystalline (mc) and nanocrystalline (nc: grain size below 100 nm) Mg-5wt% Al alloys. The Hall-Petch relationship was investigated by both instrumented indentation tests and compression tests. The test results from the indentation tests and compression tests match well with each other. ...
متن کاملEVALUATION OFDISLOCATION STRUCTURE AND CRYSTALLITE SIZE IN WORN AL-SI ALLOY BY X-RAY DIFFRACTION
Abstract: powerful method for the characterization of microstructures of crystalline materials in terms of crystallite size anddislocation structures. In this paper the effect of the sliding on the microstructure of A356 in the as-cast and heattreated conditions are studied, The X-ray phase analysis shows that with increasing applied load, the dislocationdensity is increased, whereas the crysta...
متن کاملLocalized Recrystallization in Cast Al-Si-Mg Alloy During Solution Heat Treatment: Dilatometric and Calorimetric Studies
During heat treatment, the work piece experiences a range of heating rates depending upon the sizes and types of furnace. When the Al-Si-Mg cast alloy is heated to the solutionizing temperature , recrystallization takes place during the ramp-up stage. The effect of heating rate on recrystallization in the A356 (Al-Si-Mg) alloy was studied using dilatometric and calorimetric methods. Recrystalli...
