Jul 08, 2008 · The microstructure uniformity was improved for faster cooling and higher isothermal temperatures up to 1300 °C, due to the retention of a moderate volume fraction of 2 grains and lamellar colonies. By increasing the annealing temperature from 1300 °C to 1340 °C, the accelerated formation of a limited number of lamellar colonies was found to significantly reduce the microstructure uniformity. Assessment of long-lasting effect of various doses of 1. Ann Univ Mariae Curie Sklodowska Med. 1987;42:189-92. Assessment of long-lasting effect of various doses of Sinequan on microstructure of the male gonad of the white rat.

In the study there was conducted characteristics of macro-and microstructure of casted Ti-47Al-2W-0.5Si alloy, based on intermetallic TiAl phase. There were presented possibilities for change of unfavorable parameters of this structure large grain and high content of columnar grains through the use of modifier in the form of a crystalline neodymium. Effect of heat treatment and aging on the microstructure Figure 1 shows an example of how the microstructure and thus the strength of a solution-annealed starting material changes as a result of thermal aging at 600°C to 900°C for periods of up to 1080 h. The first significant changes in the behavior of the material in a cyclical test become evident after an aging period of 120 h. In TEM images of the sample aged for 120 h at 700°C, clear
Dec 04, 2009 · In a population-based cross-sectional study, we examined effects of sex and age on bone microstructure at the wrist using high-resolution 3-D pQCT. Compared with women, men had thicker trabeculae in young adulthood and had less microstructural damage with aging. Microstructure and Residual Stresses - Fraunhofer IWMMicrostructure assessment. Microstructures are responsible for the properties of raw materials and therefore for the properties of the resulting components which are produced. Microstructures are adjusted using different manufacturing steps. In use, they can change both positively and negatively.

Oct 20, 2015 · Therefore, the purpose of the present study was to examine the effects of acupuncture on motor function and brain WM microstructure in ischemic stroke patients. Before and after four weeks of therapy, we performed diffusion tensor imaging (DTI) and a Fugl-Meyer Assessment The Effect of HIPping on the Microstructure and Tensile The effect of HIPping on the mechanical properties and microstructure of a cast Ti-6Cr-5Mo-5V-4Al alloy have been investigated. In the cast condition, the alloy predominantly consists of coarse grains. In comparison to the HIPped samples, it exhibits poor mechanical properties, in particular low ductility, due to large amounts of remnant porosity.

Reference Metals Company, 1000 Old Pond Road, Bridgeville, PA 15017, USA The assessment of second pulse effects on the The effect of the second pulse on mechanical and microstructural properties was investigated. The fracture of the welds was for pulsed samples of 6 kA and 9 kA pull out with mechanical test. Due to the existence of the microstructure including the equiaxial dendritic and finer in fusin zone in the pulsed current of 9 kA, the maximum fracture
The composition and microstructure factors are interrelated, so it is difficult to separate out the influence of each individually. In this investigation, methods were developed to study the effects of RA grain size and neighboring microconstituents in a silicon-alloyed low-carbon (0.2C1.6Si1.6Mn) TRIP steel.
