MIM is currently the most scientific near net shape forming technology for metal parts formation. It can flexibly adjust to various performance indexes and has been successfully applied to popular areas such as auto parts, 3C digital, medical equipment and tool locks. Hence, traditional molding technologies such as CNC fine processing, to some extent, are being replaced. Although the future of MIM holds many promises, there is much room for development. In terms of industry competition, to be well ahead of peers and competitors, enterprises must equip themselves with stable technical talents, superior resources and a group of talented personnel with emphasis on constant technological innovation as well as management system optimization.To boost the technological advancement and steady deve...

A team of the TSU Laboratory of High-Strength Crystal Physics is creating highly entropic alloys that differ in the unusual structure of the crystal lattice. They provide new materials with mechanical characteristics that make them suitable for use in the extreme conditions of space and the Arctic – at high and low temperatures, under load, and when exposed to radiation.The object of the physicists’ study is the high-entropy alloys FeNiCoCr (+ Al, TiAl and Mo). Compounds with this chemical composition are used only in the polycrystalline state. The laboratory staff, led by its head Yury Chumly...

To reduce the manufacturing costs of making tungsten carbide tools, a team of researchers at the U.S. Army Research Laboratory has figured out how to 3D print it into the exact size and shape they want, with little to no post-machining required, according to a U.S. patent application first made public on Thursday.Tungsten carbide is hard, so hard that it’s expensive to make it into useful tools and shapes. The current manufacturing process takes five steps, the last being grinding for quality control.Tungsten carbide is nearly twice as hard and twice as dense as steel, and when you shoot it in...

European aluminium scrap prices have plunged in recent weeks on heavy oversupply and low demand, as China's caps on scrap imports push more volume into a European market where demand from the mainstay automotive industry has shown marked weakness this year.But some relief for beleaguered scrap sellers could be set to emerge in the form of more Chinese import demand — not for the scrap units denied under government policy, but for the aluminium alloy ingots produced from those units.'In China, the lack of scrap has led to a lack of alloy ingots,' one alloy producer said. 'We're now exporting to...

NEW DELHI - India is considering extending by four months a compliance deadline on tougher import rules for steel that are aimed at forcing automakers to use locally made alloy, said two sources familiar with the matter. Compliance to the new rules had been set for Feb. 17, which was an extension of two months, but strict adherence to the regulations would have stalled production for India's auto industry, a federal minister has warned. India's auto manufacturing sector is  dominated by Maruti SuzukiNSE -1.10 %, Hyundai Motor Co, Honda Motor Co and Ford Motor Co. Carmakers ...

Aluminium alloys are widely used in many industrial applications including automobiles and aeroplanes, on account of their light weight. However, the wide-spread use of such alloys was contingent on the discovery of precipitate strengthening as a means for improving the tensile properties of these alloys necessary for most applications. Discovered over a hundred years ago, the technique involves heating alloys to elevated temperatures, which allows nanoscale secondary phases to precipitate in the metal. These precipitates hinder dislocation motion throughout the material and greatly increase t...
