Alloy - Wikipedia
An alloy is a mixture of chemical elements of which in most cases at least one is a metallic element, although it is also sometimes used for mixtures of elements; herein only metallic alloys are described.

2017年8月29日 · An alloy is a mixture of metals that has bulk metallic properties different from those of its constituent elements. Alloys can be formed by substituting one metal atom for another of similar size in the lattice (substitutional alloys), by inserting smaller atoms into holes in the metal lattice (interstitial alloys), or by a combination of both.

2020年11月11日 · An alloy is a substance made by combining together two or more elements where the primary element is a metal. Most alloys form by melting the elements together. Upon cooling, an alloy crystallizes into a solid, intermetallic compound, or mixture that cannot be separated using a physical method.

2024年12月12日 · alloy, metallic substance composed of two or more elements, as either a compound or a solution. The components of alloys are ordinarily themselves metals, though carbon, a nonmetal, is an essential constituent of steel. Alloys are usually produced by melting the mixture of ingredients.
Alloys: Characteristics, Classification, Types, Benefits, Limitations
2023年7月1日 · An alloy is defined as a combination of materials composed of two or more metallic elements, or a metallic element combined with one or more non-metallic elements. The resultant alloy exhibits distinct characteristics compared to the constituent elements, such as enhanced strength and hardness.

In an alloy, there are atoms of different sizes. The smaller or bigger atoms distort the layers of atoms in the pure metal. This means that a greater force is required for the layers to slide...
What is an alloy? - ChemTalk
An alloy is a mixture of two elemental materials to make a metallic substance. The main component is a metal (often more than one metal) and metallic properties are retained in the new mixture. An alloy can be either a compound (solid) or solution (liquid).

2022年9月21日 · Alloys. An alloy is a mixture composed of two or more elements, at least one of which is a metal. You are probably familiar with some alloys such as brass and bronze. Brass is an alloy of copper and zinc. Bronze is an alloy of copper and tin. Alloys are commonly used in manufactured items because the properties of these metal mixtures are often ...
