High temperature alloy refers to iron, nickel, cobalt as base, can in the 600-1200 ℃ high temperature and must stress under the action of a kind of metal materials long-term work; And it has higher temperature strength, good resistance to oxidation and corrosion resistance, good fatigue performance, the fracture toughness, and other comprehensive performance. High temperature alloy for a single austenitic organization, in all kinds of temperature has good stability and reliability of the organizations use, based on these properties, and high temperature alloy alloying degree is higher, also called "super alloys", it is widely used in aviation, spaceflight, petroleum, chemical industry, ships is a kind of important material. According to the matrix element to points, high temperature alloy and divided into iron base, nickel and cobalt base, high temperature alloy etc. Iron base high temperature alloy using temperature normally only up to 750 ~ 780 ℃, in the higher temperature of the heat used parts, used the nickel and refractory metal based
1;High temperature alloy with high temperature strength.
2;Good resistance to oxidation and corrosion resistance performance.
3;Good fatigue performance, the fracture toughness, plastic.
High temperature alloy for a single (austenitic) matrix organization, in all kinds of temperature has good stability and reliability of the organization to use.
High temperature alloy quality requirements:
External quality: external contour shape, size accuracy, the surface defect cleaning method.
Internal quality: chemical composition, structure, mechanical and physical and chemical properties.
Mechanical properties: room temperature and high temperature tensile properties and impact toughness, high temperature lasting several creep properties, hardness and high weeks and weeks, creep, fatigue performance under the mutual action of fatigue and the mechanical properties, thermal and corrosion resistance to oxidation.
