Structure and Classification of Titanium Alloys

Base knowledge of titanium Titanium is an important structural metal developed in the 1950s. Titanium alloys are widely used in various fields because of their high specific strength, good corrosion resistance and high heat resistance. Many countries in the world have recognized the importance of titanium alloy materials, and have successively studied and developed them, and obtained practical application. Titanium is the fourth B element in the periodic table. It looks like steel and has a melting point of 1 672 C. It is a refractory metal. Titanium is abundant in the crust, far higher than common metals such as … ਹੋਰ ਪੜ੍ਹੋ

Is cold upsetting the same as cold extrusion? What’s the difference between them?

Let ‘s just cut into the case. What is cold extrusion? Cold extrusion of cold extrusion workpiece is to place metal blank in the cold extrusion die cavity. At room temperature, pressure is exerted on the blank through the fixed punch on the press, so that the metal blank can produce plastic deformation and the processing method of parts is made. Obviously, cold extrusion processing relies on the die to control the metal flow, and depends on the large volume of metal to rotate. Move to form parts. In terms of extrusion equipment, our country has the ability to design … ਹੋਰ ਪੜ੍ਹੋ

Characteristics and Application of Common Bearing Materials

As we all know, there are many kinds of bearing materials in the market. There are three kinds of common bearing materials: metal materials, porous metal materials, and non-metamaterials. Metal Materials Bearing alloys, bronze, aluminum-based alloys, zinc-based alloys, etc. are all metal materials. Among them, bearing alloys, also known as white alloys, are mainly alloys of lead, tin, antimony or other metals, which have low strength under heavy load and high-speed conditions. The reason is because of its characteristics, such as good wear resistance, high plasticity, good running-in performance, good thermal conductivity, good glue resistance and good adsorption with oil. However, … ਹੋਰ ਪੜ੍ਹੋ


Quenching crack is a common quenching defect, which is caused by many factors. Because the defects of heat treatment begin with product design, the work of preventing cracks should start with product design. It is necessary to select materials correctly and design structures rationally, put forward appropriate technical requirements for heat treatment, properly arrange technological route, select reasonable heating temperature, holding time, heating medium, cooling medium, cooling method and operation mode, etc. Material aspect 1. Carbon is an important factor affecting quenching tendency. With the increase of carbon content, MS point decreases and quenching tendency increases. Therefore, under the condition … ਹੋਰ ਪੜ੍ਹੋ
