in the range of 60?-90? impact angles. Erosion loss of the coatings occurs through brittle breaking, cutting and fatigue spalling. Key words: high velocity arc spraying (HVAS); coating; erosion...) shows the morphology of the FA3 worn surface at 60? impact angle. The cutting and fatigue spalling can be observed as well, but without large size fracture. In high magnification (Fig.7(d), the area......
introduced during manufacturing processes. Despite the efforts taken to understand the influence of these microstructural heterogeneities on the high cycle fatigue (HCF) behavior of these alloys [11... that the fatigue life prediction referred above is focusing on high-cycle fatigue (require more than 104 cycles to failure) in which materials are subjected to small stresses (below yield stress, YS......
cycles is in good agreement with the growth of PSBs and micro-cracks. In addition, it has no significant effect on the experimental results for the changes of low- and high-cycle fatigue and the fatigue...- and high-cycle fatigue and the fatigue mode with tension-tension and tension-compression. Although the six samples are from the same batch of material, there are still some individual differences of internal......
Thermal Fatigue Behavior of SiC/MBAS Glass Coated Carbon/Carbon Composites () 摘要:The thermal fatigue behavior of C/C composites coated with the SiC/MBAS glass (MoSi_2 particle-containing boron... glass coating had an excellent thermal shock resistance in air at temperature up to 1873 K. During quick thermal cycle between 1873K and room temperature in air, the decrease of mass and mechanical......

Effect of Pre-corrosion on Fatigue Life of High Strength Steel 38CrMoAl刘建华School of Materials Science and Engineering, Beihang University摘 要:The effect of pre-corrosion on fatigue behavior of high strength steel 38CrMoAl was investigated with a fatigue test method using the accelerated pre-corrosion specimen in the neutral salt spray environment......
all the aforesaid conditions, the feasible limits of the factors were chosen in such a way that the failure occurs in LOP region and in high cycle fatigue (> 104 cycles) region... 10 January 2011 Abstract: Empirical relationship was developed to predict the fatigue life of gas metal arc welded (GMAW) cruciform joints failing from root region. High strength, age hardenable......

However, the excess heat carried by EHW is typically ignored and discharged into the environment, resulting in heat loss and heat pollution. An organic Rankine cycle (ORC) is an attractive technology......
, five experimental beams were tested under static load and fatigue load with constant amplitudes. The results indicate that the beams still have high bearing capacity even when brittle fracture... and the residual strain of concrete and reinforcing steel with the increase of the fatigue cycle loads. The studies of the existing S-N curves were compared with the experimental data including the present......
