The order of metal mobility of titanium, whether titanium alloy is more active or silver is more act

Chemical Composition Sheet Titanium Ziphenanthrene**.

Titanium is inactive at room temperature and reducible at high temperatures.

Between aluminium and zinc.

Quenching and tempering of steel needles.

Summary. 1. The physical and chemical properties of silver are relatively stable, the thermal and electrical conductivity is very good, the quality is soft, and the ductility is rich. Its reflectivity is extremely high, up to more than 99%.

Titanium is a new type of metal, the performance of titanium is related to the content of carbon, nitrogen, hydrogen, oxygen and other impurities, the purest titanium iodide impurity content does not exceed, but its strength is low, high plasticity. 2. Different usesSilver is usually used in the manufacture of highly sensitive physical instrument components, various automation equipment, rockets, submarines, computers, nuclear devices and communication systems. A large number of the contact points in all of these units are made of silver.

Titanium alloys are mainly used in the manufacture of compressor parts for aero engines, followed by rockets, missiles, and high-speed aircraft.

Hello dear<>

The answer you are looking for: the microstructure and performance characteristics of titanium alloyThe microstructure of titanium alloy mainly includes two forms: phase and phase.

Phase is the main microstructure form of titanium alloy, which has good toughness and plasticity, but low strength and hardness. The phase has higher strength and hardness, but less toughness and plasticity. The properties of titanium alloys depend on the ratio and distribution of phases and phases.

Performance characteristics: high strength: titanium alloy has high strength, even higher than some conventional steels.

In high-temperature and high-pressure environments, the strength and durability of titanium alloys are particularly outstanding. Lightweight: The density of titanium alloy is low, about half of that of steel, but the strength is quite high, so titanium alloy is widely used in aviation, aerospace and other fields, which can effectively reduce weight and improve load capacity.

Corrosion resistance: Titanium alloy has good corrosion resistance, can withstand the erosion of various chemical media, and can maintain good corrosion resistance even in seawater. Good biocompatibility:

Titanium alloys have good biocompatibility and are widely used in the medical field, such as making artificial joints, implants, etc. Good high-temperature stability: Titanium alloy has good high-temperature stability, which can maintain good mechanical properties and chemical stability in high-temperature environments.

In short, titanium alloy has become an important structural material due to its high strength, light weight, corrosion resistance, good biocompatibility and other characteristics, and has been widely used in aviation, aerospace, medical and other fields.

Hello dear, glad to answer for you. The structural structure and performance characteristics of titanium alloy are as follows: titanium alloy is mainly used for the manufacture of aircraft and engine materials, such as forged titanium fans, compressor discs and blades, engine hoods, exhaust devices and other parts, as well as structural frame parts such as girder partition frames of aircraft, mainly using the high specific strength, corrosion resistance and low temperature resistance of titanium alloy to manufacture various pressure vessels, fuel tanks, fasteners, instrument straps, frames and rocket shells.

Characteristics of titanium alloys. 1.High thermal strength, the use temperature is several times higher than that of aluminum alloy, it can still maintain the required strength at medium temperatures, and can work for a long time at a temperature of 450 500. These two types of titanium alloys still have a high specific strength in the range of 150 500, while the specific strength of aluminum alloy at 150 decreases significantly.

The operating temperature of titanium alloy can reach 500 °C, while that of aluminium alloy is below 200°C. 2.Good corrosion resistance, titanium alloy works in humid atmosphere and seawater medium, and its corrosion resistance is far from stainless steel; Particularly strong resistance to pitting, acid etching, and stress corrosion; It has excellent corrosion resistance to alkali, chloride, chlorine, nitric acid, etc.

However, titanium has poor corrosion resistance to reducing oxygen and chromium salt media. 3.Good low-temperature performance, titanium alloy can still maintain its mechanical properties at low temperature and temperature.

Titanium alloys with good low-temperature properties and very low interstitial elements, such as Ta7, can also maintain a certain plasticity at -253. Therefore, titanium alloy is also an important low-temperature structural material. Kiss <>

The above is my answer to this question, if you think I am very satisfied, please pay attention to me and not get lost in the future, and then please do a little manual in the lower right corner, give me a like! Welcome to consult again <>

a According to the information obtained in a box in the periodic table, the name of this element is titanium, which is a metallic element, so the option is incorrect

b According to the information obtained in a box in the periodic table, the atomic number of this element is 22; According to the atomic number = nuclear charge number = number of protons = number of electrons outside the nucleus, then there are 22 electrons outside the nucleus of the element, so the option is wrong

c According to the information obtained in a box in the periodic table, it can be seen that the relative atomic mass of the element is "1", not "g", so the option is wrong

d In the periodic table, the element titanium is located in the 4th period, so there are four electron shells outside the nucleus of the titanium atom, so the option is correct

Therefore, choose D
