According to the latest quarterly analysis of the natural gas market released by the International Energy Agency, global natural gas consumption will decline slightly this year and increase slowly in the following years because of soaring prices and the possibility of further reductions in Russian natural gas supplies. Global natural gas use this year is expected to be 0.5% lower than the 2021 level, and global natural gas demand is expected to increase by only 140 billion cubic meters over 2021 by 2025, the report said. The annual growth in 2021 will reach 175 billion cubic meters.
At the same time, the IEA's forecast for natural gas demand growth by 2024 was 60 per cent lower than its previous forecast, mainly due to "a weak economy and a smaller energy shift from coal or oil to natural gas", the report said.
It is worth noting that the South Korean Ministry of Industry, Trade and Resources announced on the same day that it plans to increase the proportion of nuclear power in South Korea's national energy structure to more than 30% by 2030. The proportion is 27.4% in 2021. The department also announced the resumption of the construction of two nuclear reactors. According to reports, after taking office, South Korean President Yoon Sik-Yue rejected the previous government's plan to phase out nuclear power and promised to increase investment in the nuclear power industry, so as to regain South Korea's status as a major exporter of safe nuclear reactors.

Overview of Nitinol Powder
Nitinol is a metal alloy of nickel and titanium in which the atomic percentages of the two elements are approximately equal. Different alloys are named according to the weight percent of nickel, such as nickel. Nitinol 55 and Nitinol 60. Displays shape memory effect and superelasticity at different temperatures. Miron Nitinol powder, Ni-Ti alloy powder particle size: 15-53 microns Ni:Ti:5:5
What memory alloy is Nitinol? Nitinol is a shape memory alloy, a special alloy that can automatically restore its plastic deformation to its original shape at a certain temperature. Its expansion rate is more than 20%, its fatigue life is 7 times that of 1*10, its damping characteristics are 10 times that of ordinary springs, and its corrosion resistance is better than the best medical stainless steel at present, so it can meet various requirements in engineering It is an excellent functional material that can meet the needs of medical applications.
In addition to its unique shape memory function, memory alloys also have excellent properties such as wear resistance, corrosion resistance, high damping and superelasticity.
What are the properties of Nitinol? Nitinol has two closely related and unique properties: the shape memory effect and superelasticity (also known as pseudoelasticity). Shape memory is the ability of Nitinol to deform at a certain temperature, retain its deformed shape after the external force is removed, and then return to its original undeformed shape when heated above its "transition temperature". Superelasticity is the ability of a metal to undergo large deformations and immediately return to its undeformed shape after removal of an external load. The amount of deformation of Nitinol is 10 to 30 times that of ordinary metals, and it can restore its original shape. Whether Nitinol exhibits shape memory effect or superelasticity depends on whether it is above a specific transformation temperature of the alloy. Below the transition temperature, it exhibits a shape memory effect.
Superelasticity of Nitinol Wires
This "superelastic" effect allows the use of nitinol wire devices that have been bent or shaped to allow for introduction or use in vivo. Tools such as small grasping and biopsy devices can protrude from the tube and extend over a much larger area than devices made from standard alloys. Nitinol's reduced weight and unique properties make it particularly attractive for biomedical applications including heart valve tools, stents, nails, bone anchors, complex septal defect devices and various implants.
However, heat-treating nitinol is delicate—critical for fine-tuning the transition temperature. Aging time and temperature control the precipitation of various nickel-rich phases, thereby controlling the nickel content in the nickel-titanium lattice. Aging increases the transition temperature by depleting the nickel matrix. The combination of heat treatment and cold working is very important to control the properties of Nitinol.
Applications of Nitinol Powder
Nitinol powder can meet the needs of various engineering and medical applications and is an excellent functional material. In addition to its unique shape memory function, memory alloys also have excellent functions such as wear resistance, corrosion resistance, high damping and superelasticity.
The tensile strength of Nitinol can reach 1000 MPa, which means that it takes more than 100 grams per square millimeter to break it. This force is stronger than ordinary steel, and it also has good "memory" properties and corrosion resistance.
Nitinol is 50% nickel and 50% titanium, which means 50% nickel and 50% titanium. The temperature range of the shape memory can be adjusted by the control element. Generally, the higher the nickel content of Nitinol, the lower the working temperature. When it contains 55% nickel and 45% titanium, the memory alloy can work at room temperature.
People take advantage of this property of shape memory alloys to make pearl necklaces and bracelets made of shape memory alloy wires, as well as bras woven from shape memory alloy wires. Wearing these decorations and health products on the body will restore the original curvature and rigid body temperature under the action, thus playing the role of decoration and health care. In addition, you can use Nitinol to make orthodontic wires to straighten deformed teeth according to the human oral temperature.
Nitinol can be used to replace traditional actuators (solenoid valves, servo motors, etc.), such as the simple hexapod robot Stiquito.
Nitinol springs are used in fluid thermal valves, where the material acts as both a temperature sensor and an actuator.
The alloy is used as autofocus actuators in action cameras and optical image stabilizers in mobile phones.
Alloys are used in pneumatic valves for a comfortable seat, which has become the industry standard.
The alloy Chevrolet Corvette contains a Nitinol actuator that replaces the heavier electronic transmission to open and close the hatch to release air in the torso, making it more accessible.
