Microstructural Evolution and Mechanical Properties of Type 304 L Stainless Steel Processed in Semi-Solid State
The paper discusses the effect of semi-solid processing on the microstructural evolution and mechanical property of 304L stainless steel. For the study, steel specimens were part ially melted and cooled to room temperatures in different cooling medium. The effect of temperature, t ime and cooling medium on microstructural evolution was studied by using optical microscopy. It was found that melt...
متن کاملThe T6 Heat Treatment of Semi-Solid Metal Processed Alloy A356
A solution treatment of 1 hour at 540 o C provided the best results for rheocast alloy A356-T6. Natural aging has a significant influence on the subsequent artificial aging response of the alloy. Arrhenius-type equations were derived to predict the time-to-peak hardness as a function of artificial aging temperature.
متن کاملInvestigation of the T4 and T6 Heat Treatment Cycles of Semi-Solid Processed Aluminium Alloy A356
The heat treatment cycles that are currently applied to semi-solid processed components are mostly those that are in use for dendritic casting alloys. These heat treatments are not necessarily the optimum treatments. It is shown that a decrease of the solution treatment time at 540 o C from 6 hours to 1 hour does not alter the T4 or T6 tensile properties of the SSM processed A356 alloy. Slightl...
متن کاملStructural cooperativity in histone H3 tail modifications.
Post-translational modifications of histone H3 tails have crucial roles in regulation of cellular processes. There is cross-regulation between the modifications of K4, K9, and K14 residues. The modifications on these residues drastically promote or inhibit each other. In this work, we studied the structural changes of the histone H3 tail originating from the three most important modifications; ...
