increasing. It was because that the cracks were preferentially initiated and propagated in the interior of X-phase during the tensile test.关键词:......
nearby the zero ductility temperature (ZDT) increases with decreasing solid fraction. Internal cracks can be initiated when the accumulated strain exceeds the critical strain or the applied tensile......
and the notch concentration factor Kt = 1. Fatigue cracks initiated preferentially at micropores, which had great effect on the HCF properties. The effect decreased with the decrease of pore size......
cracks were found to be initiated in the gaps between inclusions(Al2 O3, Mg O-Al2 O3) and the matrix, while other cracks originated from the interior of inclusions(Ti N, Mn S). To explain the related mechanism, the tessellated stresses between inclusions and the matrix were calculated and compared with the yield stress of the matrix. Results revealed that the inclusions could be classified into two......
). The results show that the LDX 2101 exhibits poor thermoplasticity at high temperature. The four-pass hot-rolled plates show fewer edge-cracking defects and superior thermoplasticity compared with the two-pass hot-rolled plates prepared at different temperature. The phase boundary is the weakest site in the LDX 2101. The cracks are initiated and propagated along the phase boundaries during the hot-rolling......
machine. The results indicated that, (1) the TGO grew at the interface during thermal fatigue cycle as a function of the exposure time at elevated temperature; (2) the microcracks were initiated in the top......
of a corrosion product film on the Mg-l.OCa alloy.A localized corrosion of the alloy initiated selectively on the eutectic micro-constituent zones,then enhanced with the exposure,developed in depth with ring......
of higher percentage of chloride ions on the carbon steel surface manifested that MF initiated the erosion of chloride ions on the carbon steel coupon.关键词:......
his-Amel X was designed and constructed. The protein was over-expressed and could be conveniently purified in one-step heat treatment. The mineralization process of hydroxyapatite was initiated......
configurations of the fatigue specimens were examined by OM, SEM, and TEM. The test results showed that fatigue cracks were commonly initiated from the surface grain boundaries, crystals plane, and inclusions......
