A Detailed Introduction to Shape Memory Metal

Development history of shape memory alloy Shape memory alloy is a kind of shape memory material with excellent properties. When it is affected by external force or magnetic change, it can keep its previous state, which is called shape memory effect. The application of these materials is very simple, in which the materials are easy to deform by applying external force. When they are heated to a certain temperature by external or internal heating, they will shrink or return to their original shape. In 1932, Swedish physicists first discovered this shape memory effect in Au CD alloy. By 1938, greninger … Đọc thêm

Have You Heard of Carbide Bushing

Cemented carbide bearing refers to the bearing made of cemented carbide. The hard alloy bearing has the characteristics of ultra-high wear resistance and high impact resistance. The surface and inner hole of hard alloy bearing can achieve mirror effect. performance The main material cemented carbide has a series of excellent properties, such as high hardness, wear resistance, good strength and toughness, heat resistance, corrosion resistance, etc., especially its high hardness and wear resistance, which are basically unchanged even at 500 ℃, and still have high hardness at 1000 ℃. Characteristic 1. With advanced forming technology, various kinds of hard alloy … Đọc thêm

What is low alloy structural steel

Low alloy structural steel refers to the alloy structural steel with total alloy composition less than 5%. The carbon content of this kind of steel is similar to that of low carbon steel, and it is mainly strengthened by a small amount of alloy elements to improve toughness and weldability. Its strength is much higher than that of the same carbon steel. Widely used in pressure vessels, chemical equipment, boilers, bridges, vehicles, ships and large steel structures. Alloy elements such as manganese, silicon and molybdenum cause solution strengthening. Vanadium and niobium can refine grains and improve toughness. Molybdenum can improve … Đọc thêm
