Abstract The effects of rare earth Ce on the microstructure, mechanical properties and corrosion behavior Al-Cu-Mn-Mg-Fe alloys were investigated by means microstructure analysis, tensile test electrochemical test. research shows that alloy after low temperature heat treatment mainly contains S (Al 2 CuMg) phase, T 20 Cu Mn 3 ) Al 6 (Mn, Fe) phase 7 Fe makes form new Al8Cu4Ce. appearance this has a significant refinement effect phase. Compared with Ce-free, yield strength 0.254 ω t%...
A new type of non-equivalent atomic ratio Co40Fe35Cr16Ni8Ti1 HEA that can be used as an alternative material for coronary stents was successfully designed and synthesized, one its main features the low Ni containing Ti, which made it have good biocompatibility while also achieving bidirectional improvement strength-ductility. XRD tests showed had precipitation R Laves phases. SEM equipped with EDS grains grain boundaries corroded by aqua regia appeared rich & Ti elements Co at different...
SummaryMagnesium alloy diecasting AZ91CC,* AZ61CC, AZ91HC* and AZ71HC were electroplated using three proprietary pretreatment sequences which incorporated conventional zincate immersion processes. Satisfactory peel adhesion in excess of 7.7KNm−1 was achieved on AZ61CC a sequence designated “WCM” used the same solution as Norsk Hydro process. The comparatively low AZ91HC due to its poor surface quality cast.Growth deposits monitored strip analysis technique morphology various studied scanning...
SummaryThe role of fluoride in both the second stage solution and zinc immersion stages WCM pretreatment1 sequence has been studied using techniques described previously Auger electron spectroscopy. Complete coverage magnesium alloy surface with was achieved when absent from zincating solution. However, a zero adhesion value indicated thermal cycling peel tests. The presence suppresses rate deposition affects time taken to reach equilibrium during potential/time determinations. A mechanism...
Abstract In this work, we investigate the scattering of massless plane scalar waves by high dimensional non-commutative Schwarzschild–Tangherlini black hole. We use partial wave approach to determine and absorption cross sections in incident wavelength range. Our numerical results demonstrate that bigger parameter, smaller maximum value related section, however tendency is slightly. also discovered when parameter weak, section hole oscillates low frequency zone. The total around geometrical...

In this paper, we calculated the quasinormal modes (QNMs) of a charged non-commutative black hole in scalar, electromagnetic and gravitational fields by three methods. We gave influence parameter $θ$ charge $Q$ on QNMs different fields. Thereafter, shadow radius provided valid range using constraints $\text{M87}^{\ast}$ $\text{Sgr A}^{\ast}$ from Event Horizon Telescope (EHT). addition, estimated ``relative deviation'' ($δ_{R_{s}}$) between spacetime commutative spacetime. found that maximum...
