Material scientists from NUST MISIS and the University of Western Australia have presented an innovative bioresorbable alloy based on magnesium, gallium and zinc. The material can be used for the manufacture of temporary implants in the treatment of fractures and the restoration of surgically removed areas of the bone, as well as in the treatment of osteoporosis, multiple myeloma, Paget's disease. In modern bone implantology and cardiovascular surgery, biodegradable implants, which gradually dissolve and are replaced by body tissues are increasingly being used. This approach helps minimize the inflammation of the surrounding tissue caused by the implant and eliminates the need for an implant removal operation. The benefits of using such implants are especially noticeable in pediat...

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'...

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. Ca...

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...

Scientists developed multifunctional metal alloys that emit and absorb heat at the same time and change their size and volume under the influence of a magnetic fieldScientists from Peter the Great St.Petersburg Polytechnic University (SPbPU) with their colleagues developed multifunctional metal alloys that emit and absorb heat at the same time and change their size and volume under the influence of a magnetic field. This effect is caused by changes in the structure of the substance. The alloys may be used in medicine and industry. The project was supported by the Russian Foundat...

A steel alloy developed at the Air Force Research Laboratory, called AF-9628, has the strength and toughness needed for aerospace parts. The alloys costs less than some other high-performance steel alloys, including Eglin Steel and HP-9-4-20; however, it is more expensive than common grades used in conventional munitions. AF-9628 is unique in that it does not contain tungsten, which is  found in Eglin Steel, or cobalt, which is  found in HP-9-4-20.The lab determined that AF-9628 is a good material for additive manufacturing due to its high strength. The lab tested the alloy using a p...
