This is partly due to the considerable difficulties involved in experimentally characterizing the microstructure of highly concentrated systems.

which result in anisotropic mechanical properties. The objective of this project is to investigate the anisotropic mechanical properties, crystallographic texture, and microstructure of crept zirlo materials. The anisotropic mechanical properties were investigated using uniaxial and biaxial creep tests.

microstructure and mechanical properties have become critical parameters for microelectronics reliability. Thorough reliability and compatibility tests are required to integrate new low-K dielectric materials and novel interconnects (Cu). For most reliability tests, knowledge of the thin film constitutive mechanical behavior is required.

The improvement of mechanical properties is attributed to the excellent age hardening response of Mg–RE alloys. Currently researchers have focus on the mechanical properties optimization of Mg-Gd-Y rare earth magnesium alloy [8, 9]. This paper study on effects of microstructure and mechanical

In this study, the relationship between microstructure, aging and mechanical behavior was studied for Sn-3.4Ag-4.8Bi and Sn-3.4Ag-1.0Cu-3.3Bi and compared to SAC305. The alloys were prepared in bulk form by rapidly quenching from 260 C resulting in an as-solidified microstructure similar to that observed in solder joints.

mechanical properties (e.g., Vickers microhardness and tensile properties) have also been measured and rationalized with regards to the microstructure evolutions before and after heat treatments. For EBM IN718, the results show the microstructure is not homogeneous but dependant on the location in the components, and the anisotropic mechanical

Since there are limitation of the mechanical properties of gray cast iron such as hardness, tensile strength and others so, the white cast iron is needed. The mechanical properties of white cast iron is better than grey cast iron in order to produce something that need strength and ability to against the large force exerted on it.

impacts on the mechanical properties of brass alloys [5, 6]. Quan Li et al.

owing to the large residual stress, and its refined microstructure. The weld metal had better oxidation resistance than the HAZ and base metal because of its high Cr content compared with the HAZ and base metal. In the case of the FSW, the microstructure consisted of the stir zone, thermo-mechanically affected zone (TMAZ), and base metal.
