What is Sintering Technology?

Table of Contents introduction of sintering furnaceprinciple of sintering furnacepurpose of sintering furnace types of sintering furnaceCharacteristics of microwave sintering:Application field of microwave sintering: introduction of sintering furnace The sintering furnace is a kind of furnace which can make the solid particles of the ceramic green body bond with each other, the grains grow up, the voids (pores) and the grain boundaries decrease gradually. Through the transfer of materials, the total volume shrinks, the density increases, and finally it becomes a dense polycrystalline sintering body with a certain microstructure. principle of sintering furnace Sintering principle of cemented carbide: the bonding phase, … 続きを読む

Key Points for Stainless Steel Processing

In our daily life, no matter in small tableware or decoration, stainless steel processing is more and more widely used. So what should we pay attention to in the key points of stainless steel processing? Next, let’s have a brief introduction for you. There are many reasons why stainless steel processing is important in the application field of building stainless steel processing. Corrosion environment requires smooth surface because it is not easy to scale. The deposition of dirt can rust or even cause corrosion of stainless steel. In the spacious hall, stainless steel is the most commonly used material for … 続きを読む

Do You Have the Basic Knowledge of Cemented Carbide Materials?

Cemented carbide is the most widely used high speed machining (HSM) tool material. This kind of material is produced by powder metallurgy process, which is composed of cemented carbide (usually tungsten carbide WC) particles and soft metal bond. At present, there are hundreds of different components of WC based cemented carbides, most of them use Cobalt (CO) as binder, nickel (Ni) and chromium (CR) are also commonly used binding elements, in addition, some other alloy elements can be added. Grades of simple cemented carbide These grades used in metal cutting usually contain 3% – 12% cobalt (weight ratio). The size … 続きを読む

A Detailed Introduction to Shape Memory Metal

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 … 続きを読む

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. Table of Contents performanceCharacteristicAdvantageapplicationProducing method 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, … 続きを読む

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 … 続きを読む

General Comparison between Cast Iron and Steel

Cast iron and steel may look very similar on the surface, and they have different advantages and disadvantages from production to application. Understanding these advantages and disadvantages, and choosing the right ones may mean unforgivable differences between strength and durability and cracked or deformed parts, which can quickly lose luster. Table of Contents Carbon content MachinabilityCharacteristic Castabilitycompressive strengthImpact resistanceCorrosion resistanceMachinabilitycostSpecies of cast iron and steel Carbon content Both iron and steel are ferrous metals mainly composed of iron atoms. In manufacturing, however, it’s not that simple. There are many different alloys and grades. In fact, carbon composition is the main … 続きを読む

Application of Grain Growth Inhibitors in Cemented Carbide

When WC grains in cemented carbide are less than 0.5 μ m, the finer the grains are, the fewer the defects are, and the higher the bending strength and hardness are The particle size of WC powder used to produce ultrafine cemented carbide is much smaller than that of WC powder used in general cemented carbide. The WC powder has high activity and is easy to cause grain growth in the sintering process, which is one of the crack sources. At present, there are two main methods to control the grain size: First, a new sintering process is adopted. The … 続きを読む

Something Informative about Metallurgy

Powder metallurgy is the technology of making metal powder or using metal powder (or mixture of metal powder and non-metal powder) as raw material, through forming, sintering, and manufacturing metal materials and various types of products. There are some similarities between powder metallurgy and ceramic production, which belong to powder sintering technology. Therefore, The metallurgy technology can also be used in the preparation of ceramic materials. Due to the advantages of powder metallurgy technology, it has become the key to solve the problem of new materials and plays an important role in the development of new materials. Table of Contents Application fields of powder … 続きを読む
