passes 4 Conclusions (1) Varying SiC volume fraction from 6% to 10% led to a graded structure. Different properties of Al/SiC functionally graded composites yield 5.3 μm in grain size, HV 147......
. The species from sequence extraction could yield the chemical forms, physicochemical availability, and mobilization of trace metals. Generally, arsenic and other heavy metals in the acid soluble fraction......
the WN presented yield characteristics but fractured after the elastic deformation. The fracture surface morphology of the BM (Fig. 15(b)) is indicative of a brittle fracture surface without typical......
of the rock mass. Meanwhile, the anisotropy of the rock mass leads to different rock mechanics and AE characteristics. The curve of time-stress had no obvious nonlinear phase before and after yield, which......
Mechanics and Rock Engineering, 2017, 50: 2511-2520. [8] ZHANG G C, HE F L, JIA H G, LAI Y H. Analysis of gateroad stability in relation to yield pillar size: A case study [J]. Rock Mechanics and Rock......
试样的拉伸性能.测试内容包含抗拉强度(Ultimate tensile strength, UTS),屈服强度(Yield Strength, YS)和伸长率(Elongation, El),典型的C95220铸造铝青铜合金和电弧增材制造Cu-8Al-2Ni-2Fe-2Mn合金应力-应变曲线如图11所示,增材试样的拉伸结果汇总在表3中.从应力-应变曲线可以看出,尽管C95220合金的抗拉强度优于电......
yield higher fatigue properties in high- strength aluminum alloys [35]. Vickers hardness of the as-swaged, solution-treated and aged conditions were HV 164, 126 and 174, respectively. Fig. 11 Aging......
(UTS) and yield strength (YS) decrease for the Mg-1Zn- 0.2Ca-2Ag alloy wires and then increase when the addition of Ag reaches 4%, while the trend of elongation is just opposite against the strength......
by marking 50 mm gauge length. The approximation of yield strength was done by applying 0.2% offset strain approach on stress-strain curve. The analysis of tensile fractured surface was executed......
(graphite-like structure) bonds will lead to a variety of desired properties in carbon materials such as DLC coatings. The dense diamond-like structure has an important role in increasing yield strength......
