“Break through the blockade and high-quality development require strong new material technology to support.” Gan Yong pointed out that at present, my country is in a strategic transition period of opening up new economic growth points and improving the environmental carrying capacity, which provides a great opportunity for the development of new materials in my country. A rare historical opportunity.

He said that in the transition period of transformation and upgrading and the development of new industrialization, my country's strategic demand for new materials is particularly prominent. For example, by 2030, the construction of thousands of ultra-supercritical thermal power units at 600 degrees Celsius and 700 degrees Celsius will require tens of millions of tons of heat-resistant steel and heat-resistant alloys; the development of bearing steel, gear steel, and die steel for high-end equipment and basic parts The annual demand reaches 3 million tons, 2 million tons and 500,000 tons respectively; the annual demand for steel and corrosion-resistant alloys for the construction of marine resource exploration, mining, storage and transportation and infrastructure reaches 600,000 tons. "At present, some of the high-end and large-format new materials needed for the development of the new generation of information technology industry and the construction of the aviation equipment industry rely on imports, and the independent guarantee rate is less than 15%." Gan Yong pointed out.

"According to the strategic and urgency, taking into account major national scientific and technological tasks and related plans and arrangements, the Chinese Academy of Engineering has focused on key materials that the country’s major strategic needs depend on, covering four major strategic areas such as delivery vehicles, national defense and military industry, energy and power, and information display. A strategic system and 84 strategic products.” Qian Yong introduced in detail the key materials and their demand characteristics for the three strategic areas of delivery vehicles, energy and power, and information display.

In the field of delivery vehicles, five types of strategic systems such as heavy helicopters, new energy vehicles, high-speed trains, long-range wide-body passenger aircraft, and heavy-duty launch vehicles require 24 strategic products, involving high-strength carbon fiber composite materials, high-capacity rare earth hydrogen storage alloys, and high thermal conductivity magnesium alloys. , 39 kinds of materials such as high wear-resistant die steel and high temperature alloy. Take high-speed rail as an example. High-speed rail has become China's business card, but the running parts and brake parts of the 350 kilometers per hour high-speed rail still partly rely on imports.

In the field of energy and power, five types of strategic systems such as deep-sea energy drilling and production platforms, ultra-supercritical thermal power units, heavy ground gas turbines, magnetic drive power systems, and flexible power transmission and transformation systems require 18 strategic products, involving high-strength non-magnetic stainless steel, high-strength and low-strength. 25 kinds of density steel, anti-fatigue low alloy steel, etc. Gan Yong specifically pointed out: "It is necessary to give priority to the development of key structural parts of 700 degrees Celsius ultra-supercritical power station steam turbines, heavy-duty surface gas turbines, deep-sea energy drilling platforms, ultra-large offshore wind power, flexible AC and DC power transmission and transformation devices, and new magnetic power systems. Typical equipment or system."

In the field of information display, 4 types of strategic systems such as laser display, printed display, Micro-LED display, and special light sources require 13 strategic products, involving 23 materials such as high-efficiency infrared rare earth luminescent materials, rare earth scintillation crystals, and silicon carbide. Gan Yong said that by 2030, my country's annual demand for new display materials will reach 350 million square meters, and it is necessary to accelerate breakthroughs in next-generation display technologies and their key materials. Especially in terms of sensing materials, the development of high-speed rail, airplanes, and 5G communications put forward higher requirements for sensing materials. He pointed out that only the continuous development of new sensing materials can meet the requirements of the increasingly complex application environment of sensor devices.
