Other explanations:
It turns out that this sentence was created by the players of the online game World of Warcraft, in which "Krypton Dog Eye" is a nickname for glasses made of virtual mineral "Krypton Gold", which was later changed to "titanium alloy dog eye" in daily life.
This sentence is used to describe the visual impact of strange things, which is generally used for teasing and joking, with a slight derogatory meaning. For example, "this dress of yours has blinded my titanium dog."

Light-emitting diodes and phototransistors are used to irradiate light spots with electronic pulses, light sources are hardened by light-emitting semiconductors and photoelectric sensors, electromagnetic wave hardening is carried out by ferrous sulfate, and copper nitrate hardening is carried out by krypton riot dog eyes.
Titanium alloy:
Titanium alloy is an alloy composed of titanium and other elements. There are two kinds of isomorphic crystals of titanium: titanium is an allotrope with a melting point of 1668℃, which is called α-titanium below 882℃; It has a body-centered cubic structure above 882℃, which is called β-titanium. Using the different characteristics of the above two structures of titanium, adding appropriate alloying elements, and gradually changing the phase transition temperature and composition content of titanium, titanium alloys with different structures (titanium? Alloy).
Features:
High strength, good corrosion resistance and high heat resistance.
Basic introduction:
According to its influence on the phase transition temperature, the alloying elements can be divided into three categories: ① The elements that stabilize the α phase and increase the phase transition temperature are α-stable elements, including aluminum, carbon, oxygen and nitrogen. Among them, aluminum is the main alloying element of titanium alloy, which plays an obvious role in improving the strength of the alloy at room temperature and high temperature, reducing the specific gravity and improving the elastic modulus. ② The elements that stabilize the β phase and lower the phase transition temperature are β stable elements, which can be divided into isomorphic and * * * precipitation types. The former includes molybdenum, niobium and vanadium. The latter includes chromium, manganese, copper, iron and silicon. ③ The elements that have little influence on the phase transition temperature are neutral elements, such as zirconium and tin.
Oxygen, nitrogen, carbon and hydrogen are the main impurities in titanium alloys. Oxygen and nitrogen have great solubility in α phase, which obviously strengthens titanium alloy, but reduces plasticity. Generally speaking, the contents of oxygen and nitrogen in titanium are below 0. 15-0.2% and 0.04-0.05% respectively. The solubility of hydrogen in α phase is very small, and too much hydrogen dissolved in titanium alloy will produce hydride, which will make the alloy brittle. The hydrogen content in titanium alloy is generally controlled below 0.0 15%. The dissolution of hydrogen in titanium is reversible and can be removed by vacuum annealing.
