Heusler alloys are magnetic materials made from three different metals that are not magnetic individually. The alloys are used broadly for their magnetic and thermoelectric properties, and their ability to regain their original shape after being deformed, known as shape memory. Investigations by Tohoku University's advanced materials scientist An-Pang Tsai and colleagues now show that these materials can also be fine-tuned to speed up chemical reactions. Heusler alloys have a typical composition of two parts metal X, one part metal Y, and one part metal Z (X2YZ). Each of the three come from a distinct region of the periodic table of elements. The original Heusler alloy, discovered in 1898, was Cu2MnAl, made from copper, manganese and aluminium. Many other combinations of met...

In order to be able to exploit the lightweight construction potential of aluminum in the aerospace industry, scientists from Bremen, are involved in a project to further develop aluminum alloys for additive manufacturing.During the two years of funding, the first step will be to further develop an already available high-performance alloy in such a way that it can also be used in space travel. At the same time, the scientists want to develop a novel aluminum alloy with similarly outstanding material properties as the already available high-performance alloy, but as a cost-ef...

Did you know steel roofs can last over 50 years while traditional roofs only last 17 years?Are you constructing with steel? Steel comes in many types, shapes, and sizes. To ensure you’re using the best, here are the 7 types of steel.The 7 Types of Steel to Use in ConstructionWhen it comes to construction there is no material like steel. No material can match the durability. Let’s chat about 7 different types of steel.1. Structural SteelStructural steel is durable and strong. It can be transformed into any shape including but not limited to I-Beam, L shape, T shape, and Z shape. ...

Researchers at the notorious Sandia National Laboratories in New Mexico - a primary supplier of US ancillary nuclear weapon systems - have announced the development of a two-metal alloy that is so hard that only diamond can compare in its ability to resist wear.Boasting a durability and strength rating an estimated 100-times harder than high-strength steel, the platinum-gold alloy can withstand incredibly high levels of heat and friction, and can last much longer than existing materials in high-stress environments.As an added boost, the accidentally-discovered super-hard ma...

Made up of a combination of platinum and gold, the new material is apparently 100 times more wear-resistant than high-strength steel, which makes it the first metal alloy to join the same class as diamond. Even better, it naturally produces its own lubricant that, under normal circumstances, ...

Manganese ore imports continue to growGrowing imports of manganese ore continued to buoy supplies of raw materials in 2018, even as environmental issues weighed on domestic production. Imports of manganese ore reached 22.08 million mt in January-October, compared to 21.26 million mt of total imports in 2017. This is likely to increase ore supplies by 15% year on year in 2018. Output of manganese oxide ore shrinks furtherEnvironmental and safety inspections hampered production across medium-sized and small manganese oxide miners in 2018. Even with high profits in the st...
