Abstract : The two key factors for the preparation of nano / ultrafine WC – Co cemented carbides are the prep -Aration of high – quality nano/ ultrafine WC – Co composite powders and the control of grain growth during…

In metal press working, a tool that forces a metal to pass through a die under the action of an external force, a metal cross-sectional area is compressed, and a shape and a size of a desired cross-sectional area is…

Starting in the 1920s, metal products, toys, and small hardware industries used punches, presses, and other simple mechanical equipment and corresponding molds to process product blanks or certain components, including “knifehead molds” for blanking and punching. "Docking mold" for metal…

Abstract3D gel printing (3DGP) is a novel manufacturing technology that builds 3D components by depositing and gelling metal slurries layer by layer. Herein, a hydroxyethyl methacrylate (HEMA)-based slurry having a solid loading of 47-56 vol% WC-20Co was directly formed by…

Abstract: Aiming at practical training and learning，the NC lathe simulation system is designed on VB 6． 0． The system，which simulates the Fanuc-0i Mate TB NC operating system equipped by N091 NC lathe，realizes functions such as，writing NC code， checking code errors，warning…

We used metallographic microanalysis and hardness testing methods to study the cause of the failure of cold-punching mould, and proposed an effective measure to improve the life of the mold. Research shows that by optimizing the heat treatment process and…

Abstract : This paper summarizes the research progress of laser heating assisted cutting technology in recent years. In the aspect of experimental research, the processing features of laser heating assisted turning, milling, drilling and grinding are summarized, and the effects…

As we all know, phase diagrams can be tested experimentally. However, experimental phase diagrams require a lot of manpower and material resources. Under the conditions of high temperature, high pressure, and corrosive gases involved in the reaction, they will also…

Lithium batteries are widely used in electronic products and automobiles as new energy sources. In recent years, the state has vigorously supported the new energy industry, and many domestic and foreign companies and research institutes have increased their input and…

The lathe has the characteristics of machine, electricity, and liquid in one, technology-intensive and knowledge-intensive, and is an advanced processing equipment with a high degree of automation, a complicated and expensive structure. In order to give full play to its…

IntroductionAustenitic stainless steel has good corrosion resistance and oxidation resistance, but its strength is less than 300 MPa, which greatly limits the application of austenitic stainless steel in industry. At present, it is an effective measure to strengthen austenitic stainless…

1. Science: Polarity compensation mechanisms on the perovskite surface KTaO3(001)The use of scanning probe microscopy and density functional theory by Martin Setvin (Corresponding author) of the Vienna University of Technology, et al. studied the compensation mechanism of the perovskite potassium…
