Scientific and Technological Progress of the bronze

Tao, Product Research of the bronze and its construction Levin process 2009.05.04 craft room new high-strength wear-resistant complex production technology Luoyang Copper Processing Technology Center in December 2004 new high strength and wear Tao Luo, bronze and their production technologies Copper Group Technical Center PC 471 039 Abstract] high strength wear-resistant β phase based on the diverse and complex bronze, is a newly developed, and has been widely used in new high-tech, high value-added copper alloy varieties, has a broad market space for development. Taotie motif on the bronze of China has a basic core design.
This paper systematically describes the types of market demand outlook, high strength wear-resistant bronze, features, and highlights the typical alloy products production and processing technology based on thermal processing, the alloy production and development of new varieties play constructive guidance. The majority of the taotie motif on the bronze sculpture has twisted and stretched claws.  β-phase bronze, high strength wear-resistant copper alloy, precipitation phase thermal processing an Introduction Copper is the earliest human understanding and use of metallic materials, has a strong alloying ability, the formation of alloys with most elements of the nature of modern science alloy products with different characteristics and uses of technology to provide, is indispensable for the development of modern industrial engineering materials, but also caused attaches great importance to science and technology community.
Domestic and foreign research and development of new copper alloy boom in the ascendant, the birth of a large number of high-performance, high-tech alloys of new varieties, new technologies. As more and more varieties of new products, new technology, practical use, the copper alloy, the product applications become ever finer, the increasingly high demand for performance, many alloy species has become a special field of Alloy , and thus attention to the special and specific research, the market for material selection and timely development of new high-tech products to meet market demand, is a concrete manifestation of enterprises rely on scientific and technological progress to take the content development. Some taotie on the bronze is even connected with the bird designs with two obvious bird heads. Bronze is the most important copper alloy variety, low-cost high-performance, widely used in various fields of national economy.
But has long been widely used is the α and α + β phase based on single-phase or two-phase bronze alloys, and less of the β phase based on the complexity of the high zinc bronze statue research applications. With the advances in technology, the high zinc bronze deepening, found that by joining multi small amount of alloying elements can significantly improve its performance, the material has many of the practical prospects of new features, such as shape memory properties; The reason of the extensive use of taotie on the chinese bronze of Shang and Zhou can not be separated with the social politics.  with titanium bronze, beryllium copper compared to the United States and the high elastic energy; superplastic forming properties and high corrosion resistance, wear resistance, anti-friction properties.
One of the most striking is the β phase based on a new type of high-strength wear-resistant diverse and complex bronze, which has a high strength comparable with aluminum bronze, excellent wear mechanism and high corrosion resistance to various media. The bronze dragon naturally had been highly developed and reached the pinnacle of technology. More valuable is its excellent thermal processing formability, in forging a variety of sophisticated high-strength wear-resistant parts, with the incomparable advantage of other materials, so since the advent of the last century, the development of the 1970s, the rapidly growing popularity of the various requirements has high strength and good wear resistance to overload, high-speed hydraulic rotor, sliding shoe, self-lubricating bearings, precision forgings, and other fields, its typical use as shown in Figure 1.
