Based on the systematic investigation of the room temperature tensile properties of Fe3Al based intermetallic alloy under different surface conditions,phase structures,grain morphologies and in vacuum and air,the experimental results showed that only Cr improved ductility among the additions of Cr,Mo,Ti,Mn,Ni and Si.
The evaluation of the threshold stress of hot salt stress corrosion cracking (HSSCC) of Ti alloy TC11 in temperature range from 350 to 500℃ under laboratory condition and of its susceptibility influenced by five different surface conditions was made.
samples from TP304 steel surface conditions were put into the high temperature steam to test its oxidation behavior,the samp les are TP304 steel basic material,surface sedimental CeO 2 film and surface s edimental CeO 2 film after balls impact treatment.
Using the revised local stress - strain method and making allowance for the blade surface conditions, corrosion fatigue and other factors, the low and high cyclce fatigUe cracking initiation life are calculated and checked for the 665mm, 680mm and 851mm blades with satisfied results.
By using this revised method, the blade high cycle and low cycle fatigue life calculation model and program are completed. In this model the influences of surface conditions, material structure and medium corrosion are considered.
The more the content of SS+SH in the Durum wheat sulfur-rich glutenins (DSG) is,the better the surface conditions of paste are, and DSG proteins play a functional role in preventing disaggregation of the cooked paste surface;
Scientific research since mid 1990s has conducted three acquisition techniques in- cluding the high-resolution crooked line survey in valleys, high-resolution multiple straight line sur- vey and 3D survey, under different surface conditions and for different geological targets.
First,source points were distributed on the surface of the 2D cylinder,the strengths of the source points was determined through the current function satisfying the surface conditions,then the hydrodynamic coefficients was acquired when the radiation potential of the flow fluid was solved.
Based on AVHRR data of NOAA satellite in 1988-1992,crop growth vigours in summer and autumn are analysed. Combinating those information with the practical grain yield and underlaying surface conditions, the threshold differentiated by remote s. ensing NOAA/ AVHRR is defined.
b) The clear negative correlation between the summer rainfall over the northern China and the partial Asian LST is showed in April and May. (4) The findings by comparison, contrast and analysis are that the common underlying surface conditions of the anomalously heavy rainfall over the Yangtze River valley (1954, 1998 and 1999) or the Changjiang-Huaihe (1991) valley are the positive departure of SST in the Kuroshio area and the mostly positive anomaly of LST over Eurasia.
According to thermometric investigations, the olivine phenocrysts began crystallizing at T = 1280-1320°C and P >amp;gt; 3.5 kbar, whereas groundmass minerals were formed under near-surface conditions at T ≤ 1200°C.
One of the most different characteristics between the smooth and rough surface conditions was the spin-down time TD.
Also the seismic modeling examples show the good performance of this method even in the case of complex surface conditions and complicated structures.
The applied nuclear reaction technique permits the direct observation of ion distributions in an absorber and their changes by diffusion-without any influence of the surface conditions on the evaluation.
The extent and morphology of the fine-grain DIR region vary depending on the surface conditions and the composition of the Zn-source Cu-Zn alloy.
