[ 1 ] - Austenite Stability during Nanoindentation of Ultrafine and Coarse Grained AISI 304L Stainless Steels
In the present study, the effect of grain size on the austenite stability was studied by nanoindentation tests in a 304L stainless steel. Thermomechanical processing based on cold rolling and annealing was used to produce two different types of austenite: ultrafine grained (UFG) austenite with the average grain size of 0.65 μm and coarse grained (CG) austenite with the average grain size of 12 ...
[ 2 ] - سنتز و مشخصهیابی پوشش نانوکامپوزیت FeAl/Al2O3 بر زیرلایه فولادی تولید شده بهروش آسیاکاری گلولهای پرانرژی
In the present study, FeAl/Al2O3 nanocomposite coating was produced on the carbon steel plate using mechanical alloying (MA) technique via a mechanochemical reaction. Stoichiometric ratios of Fe, Al and Fe2O3 as well as a substrate were mixed and milled up to 22h in a vibrating high energy mill with a 4 mm ball. Samples prepared after 18h of MA were subjected to annealing at 773 K for 1-3 h. X-...
[ 3 ] - Evaluation of microstructure and mechanical properties of bulk nanostructured Ti5Si3 and Ti5Si3-Al2O3 nanocomposite
Mechanical alloying and vacuum sintering have been used to produce bulk nanostructured Ti5Si3 and Ti5Si3-15Wt.% Al2O3 nanocomposite. X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were used to study the microstructural characteristics of the samples. Indentation method was used to calculate hardness, elastic modulus and fracture toughness ...
