Mending the unmendable: A new method for restoring fractured metals（图）
Design Sustainability Research
2023/6/29
It’s estimated that mining, refining, and processing metals commonly used in construction, referred to as structural metals, contribute around three billion tons of CO2-equivalent emissions. And, alth...
New ‘High-Entropy’ Alloy Is As Light As Aluminum, As Strong as Titanium Alloys
High-Entropy As Light As Aluminum As Strong as Titanium Alloys
2014/12/30
Researchers from North Carolina State University and Qatar University have developed a new “high-entropy” metal alloy that has a higher strength-to-weight ratio than any other existing metal material....
Thixoinfiltration: a new approach to produce cellular and other low density metallic materials
Thixoinfiltration produce cellular density metallic materials
2010/8/12
In the last two decades, cellular metallic materials have been increasingly produced and utilized in different sectors such as building and architecture, mechanical and chemical industries, for biomed...
New tool materials based on Ni alloys strengthened by intermetallic compounds with a high carbon content
Tool materials Ni-based alloys Intermetallic compounds Carbides
2010/8/17
Tool steels containing from 0.30 to 0.60% C, up to 5% Cr and Mo, W and V are universally applied as tool materials for operations in high temperatures. Tools made of these steels obtain functional qua...
Development of a new aluminium matrix composite reinforced with iron oxide (Fe3O4)
a new aluminium matrix composite iron oxide Fe3O4
2010/8/11
In modern industry, it is more and more enforced to develop new composites, such as high resistant, alternative materials of low density in order to realise multifunctional pieces. The powder metallur...
Continuous heating from as-quenched state in a new hot-work steel
Tool materials Hot-work steel Tempering CHT - diagram
2009/12/1
Purpose: This work contains a detailed description of the kinetics of phase transformations during tempering of
a new hot-work steel. Moreover, the differences in hardness and microstructure of sampl...
New White Gold Alloys.
Metal-metal composites were first produced in a copper matrix in the 1970’s, and they have since been produced in several other binary metal systems. This strengthening technique reinforces a ductile ...
Gold: A Relatively New Catalyst
Gold Catalyst
2009/7/29
Work performed with gold catalysts before about 1980 is briefly reviewed, and early indications of the importanceof using very small particles to obtain good activity are noted. The apparent contrast ...
Scope for New Applications for Gold Arising from the Electrocatalytic Behaviour of its Metastable Surface States
Gold Electrocatalytic
2009/7/28
The electrocatalytic behaviour of gold in aqueous
media is surprisingly complex and a novel view of gold
electrode surfaces is proposed to explain the observed
electrochemical responses. The metal ...
Ever since the 1940s, chrome has been used to add a protective coating and shiny luster to a wide range of metal products, from bathroom fixtures to car bumpers.
Chrome adds beauty and durability, bu...
Chemistry of layered d-metal pnictide oxides and their potential as candidates for new superconductors
layered d-metal pnictide oxides potential new superconductors
2010/1/19
The description of the two types of layers in our article is inaccurate. All the [M2Pn2] and [M2Ch2] (M = d-metal; Pn = pnictogen; Ch = chalcogen) layers, which were described as 'fluorite-type', cons...
New version of experimental setup for investigation of linear contraction and shrinkage stresses of metals and alloys
Linear contraction Shrinkage stresses Experimental set-up
2011/3/17
A new version of an experimental set-up for examination of linear contraction and shrinkage stresses progress of metals and alloys during– and after solidification has been described. By new method th...
