Abstract Titanium alloy is vital for the propulsion system of remote-sensing spacecraft. Facing increasing threat space debris, exploring dynamical properties new titanium materials one essential technologies spacecraft protection. This paper presents results an investigation into dynamic mechanical a novel Ti-5553 β phase alloy. The was subjected to testing at temperatures 25°C, 200°C, 400°C, and 600°C, strain rates 2000 s −1 4000 , using two distinct experimental techniques: split...
The hot deformation behavior and microstructure evolution of newly developed as-cast high-density steel were investigated by performing compression tests in the temperature range 1000–1200 °C strain rate 0.001–10 s−1. Flow stress data using hyperbolic sine equation was performed to obtain constitutive relationship activation energy for steel. novel shows higher due high tungsten content. workability studied through processing map approach based on dynamic material model. When is 0.8, optimum...
Hydrothermal reactions of Cu(ii)/Zn(ii)/Cd(ii) with 5,5'-bistetrazole (H2BT) lead to three new energetic coordination polymers: [CuBT(H2O)]n (1), [ZnBT(H2O)2]n (2), and [CdBT(H2O)2]n (3). These crystal structures were determined by single X-ray diffraction. Compound 1 forms regular compact 3-D frameworks compounds 2-3 are 1-D chain structures. show prominent thermostability (Tdec = 349.1 °C for 1, 334.8 2, 394.2 3) investigated using differential scanning calorimetry (DSC) thermogravimetric...
The alkali metal salts of 3,6-dinitramino-1,2,4,5-tetrazine were synthesized and characterized, which may be excellent “green” energetic materials.

The detailed structural analysis of the doped 3 compound carried out by Rietveld refinement full XRD Pattern. Dielectric and electrical properties were studied in a wide range temperature frequency dielectric/impedance spectroscopies. comprehensive spectrum reveals occurrence two relaxation behaviors at low high frequency, respectively. A phase transition...
Cationic (<italic>S</italic>,<italic>S</italic>)-bis(oxazolinylphenyl)amido-ligated palladium species were first used for the coordination–insertion polymerization of 1-chloro-2-phenylacetylenes.
To investigate mechanical properties of Ti6321 titanium alloy, tensile tests at different strain rates are carried out. The changes microstructure and the range 10 −3 s −1 –10 5 have been studied. Lower density larger size dimples produce when stretched high 3 compared to quasi-static stretching. yield strengths alloy 805, 1096 2440 MPa , 2 × respectively with obvious rate strengthening effect. At rate, parallel twins generate grain boundaries coordinate deformation dislocations cannot meet...
Obstructive sleep apnea is a common sleep-disordered breathing disorder caused by repeated obstruction of the upper airway. Existing automatic detection models usually use time-frequency domain and nonlinear features physiological signals, some are based on deep learning. The respiratory status parameters during mostly discussed for medical purposes, yet they most direct evidence pulmonary dysfunction. This paper proposed an OSA method using calculated from nasal airflow signals including...
3-Nitramino-6-hydroxy-1,2,4,5-tetrazine (NHTZ) and its alkaline earth metal salts (Mg2+(1), Ca2+(2), Sr2+(3), Ba2+(4)) were prepared via 3,6-dinitramino-1,2,4,5-tetrazine for the first time.
