Effect of Pearlite and Phosphorus Eutectic on Properties of Ductile Iron
Performance of Pearlitic Ball-iron Castings with Vanadium and Phosphorus Additions
Abstract
Pearlitic ball-iron is a kind of cast iron commonly used for automotive parts, owing to its excellent combination of strength and machinability. In this paper, the effects of Vanadium (V) and Phosphorus (......
Mechanical Properties of Cast Brass
Introduction
The term bronze is given to an alloy of copper and tin, with other metals such as aluminum, manganese, and zinc sometimes added. Although copper has been used since the Bronze Age, bronze itself was developed around 3000 BC. Bronze has been used to create all sorts of items, from wea......
Main functions of bar and wire roughing mill
High-speed Bar Roller
Introduction
High speed bar roller is a tool used to roll rods or bars of steel and other materials into a smooth, uniform shape. It has many advantages over other rolling tools, such as being able to roll bars with little distortion, without leaving any burrs or sharp edge......
Commonly used Vickers, brinell, Rockwell hardness conversion table
When it comes to talking about the hardness of material, there are three different scales that are commonly used: the Vickers hardness test, the brinell hardness test, and the Rockwell hardness test. Each of these tests measure hardness differently, and they all have their own pros and cons. To he......
Comparison table of various hardness values
Hardness is a measure of a substances resistance to various kinds of deformation. It is defined as a measure of a materials resistance to a wide range of forces, including scratching and indentation. The ability of a material to resist these kinds of forces is related to its strength, toughness, a......
Basic knowledge of metal heat treatment (2)
2. Metal Heat Treatment Basics (II)
When a material undergoes heat treatment, the microstructures of the material are altered and refined. This can change properties such as ductility, hardness and corrosion resistance. In this article we’ll look at two heat treatment processes that can do this ......
Research on the Influence of Two Kinds of Quenching Oils on the Heat Treatment Quality of Leaf Springs (Part Two)
3. Research methods
3.1 Sample selection
In order to analyze the effect of the two kinds of quenching oils on the quality of spring heat treatment, 15 springs were selected in the factory, and each spring was divided into three samples. Sample 1 was treated with quenching oil A, sample 2 was tre......
Hardness Common Terms
Hardness is an important parameter used to measure the resistance of a solid material to physical indentation or penetration. It is a measure of the ability of a material to withstand abrasion, erosion, penetration, scratching and other surface deformations. Hardness can be defined in terms of the......
