The creep deformation behavior and rupture properties of as-quenched austenitic Fe-30Mn-9Al-1C alloy have been studied at 923, 948, and 973 K under applied stresses ranging from 50 to 350 MPa. The creep curves of the alloy exhibited an extended tertiary stage prior to failure. The stress...
℃.When the temperature is raised to 350 ℃,the tensile strength and yield strength decrease to 105 MPa and 98 MPa respectively,and the elongation increases to 23%.The poor mechanical properties are ascribed to the coarsening and transformation of the phases in Al-Cu-Mg-Ag alloy at high ...

A designed copper alloy with Ni2MnSn nano-magnetic Heusler phases exhibits a yield strength of up to 1.5 GPa, and the attenuation degree of electromagnetic waves reaches 110 dB within the frequency range of 10 kHz to 3 GHz.
The effects of Er additions on the microstructure and tensile properties of cast Al–15Zn–2.5Mg–2.5Cu aluminum alloy have been investigated. The results show that by adding 1 wt% Er grain refiner in the cast alloy, the grains can be refined to a...
The interfacial reactions and strength properties of a titanium alloy/ microduplex stainless steel diffusion bonded joint using Ni alloy as an intermediate... S Kundu,S Sam,S Chatterjee - 《Materials Science & Engineering A》 被引量: 63发表: 2013年 Microstructure and Mechanical Properties of Nano...
Properties of Aluminum Gallium Arsenide The alloy system A1GaAs/GaAs is potentially of great importance for many high-speed electronics and optoelectronic devices, because the lattice parameter difference GaAs and A1GaAs is very small, which promises an insignificant concentra... S Adachi 被引量: 0...
chemical heterogeneity in the alloy (Fig.3a). This micro-segregation acts as a barrier to grain boundary migration21and thus hinders recrystallization11. The higher the density of cells and the higher the amount of solute segregating at their boundaries, the higher the alloy’s thermal stability....
The mechanical properties of friction welds of an α+β titanium alloy (Ti–6.5Al–1.9Zr–3.3Mo–0.25Si) were evaluated in the stress relieved and in the post weld heat treated (PWHT) conditions to understand the effect of post weld heat treatments on the microstructure and mechanical propertie...
Abstract—This critical review considers the fundamental concept, methods of obtaining, stability, and properties of a new class of materials—high-entropy alloys and compounds. An analysis of factors that determine the structure and stability of multicomponent disordered solid solutions has been carried...
