Superplasticity of Aluminum Matrix Composites
？
Abstract
This paper discusses the superplasticity of aluminium-based composite materials. Superplasticity is a type of plasticity in which metals and alloys exhibit an unusually high deformation rate under tensile loading. Aluminium-based composite materials are especially interesting because t......
Age-strengthened iron-based deformable superalloy
Introduction
The high-temperature deformation alloys, called Fe-based alloys, have been widely utilized as structural materials of a variety of industrial components, due to their good mechanical properties and resistance to oxidation. However, in many applications these alloys are exposed to hig......
diamond crystal defects
Diamond crystals, or ‘diamonds’ have long been admired for their beauty and strength. The name ‘diamond’ comes from the Greek word for ‘unbreakable’ and the exquisite hardness of diamonds makes them a desirable material for jewelry and industrial applications. Diamonds most commonly occur in......
high temperature creep
High Temperature Creep
High temperature creep is a type of creep usually defined as deformation of solids (metals, ceramics and polymers) due to applied stresses at temperatures where creep is significant. Temperature plays a key role in causing and controlling creep, but other factors such as app......
Black dilute gold ore - complex dilute gold ore
Black and Secondary Gold Mines
Black mines and secondary gold mines are geological ages and are objects of geological surveys and geological prospecting. When the thickness of gold-bearing ore bodies is more than a certain thickness, or when the ore bodies are well developed or covered, black or ......
Application of Nitrogen in Microalloyed Steel
Application of Nitrogen on Microalloyed Steels
Abstract
Nitrogen, a non-metallic element, is an important additive to steels and the inclusion of nitrogen in steels can affect the steel’s physical, chemical, and mechanical properties. Microalloyed steels, which are low alloy steels, form a sepa......

The Worst Storm
It was just like any day in April. The sun was shining, the birds were singing, and I was ready for the day. I started my day by finishing my work for school, and then went for a walk to enjoy the nice weather. Little did I know, this was going to be one of the most memorable days......
Chemical Composition and Microstructure of 00Cr25Ni5Ti Steel
bstract
0Cr25Ni5Ti steel is a kind of titanium stainless steel. It is widely used for its many properties like corrosion resistance, oxidation resistance and good overheating resistance. In this paper, the major element composition and the microstructure of the 0Cr25Ni5Ti steel were studied. The ......
