Also known as mild steel, it is a low-cost material that is easy to shape. While not as hard as higher-carbon steels, carburizing can increase its surface hardness. Medium Carbon Steel:Composition of 0.29%-0.54% carbon, with 0.60%-1.65% manganese. Medium carbon steel is ductile and strong, with long-wearing properties. Hardness of Oxide Scales on Fe-Si Alloys at Room- and High Hardness of oxide scales on Fe-(0, 0.5, 1.5, 3.0)Si alloys was studied at room temperature after oxidation at 1273 K for 18 ks in oxygen, and at 1073 and 1273 K for 180 and 1080 ks in dry air, by micro-Vickers hardness measurements. After oxidation at 1273 K for 18 ks, high-temperature hardness of oxide scales on Fe-(0, 1.5, 3.0)Si alloys was also measured at 1273 K.

The lowest indentation hardness is measured in manganese alloyed FeB and Fe 2 B. In both FeB and Fe 2 B, an indentation size effect was observed, showing a decrease of hardness with increasing indentation depth. Nickel Alloys SummarizedBest Speciality Nickel Alloy Manufacturer.

Tungsten Alloy:W, Ni, Fe, Cu & Mo. These alloys contain 90% or more tungsten with nickel, iron, or copper added. Unlike pure tungsten, these materials can be conventionally machined and are less expensive. However, they cannot withstand the extremely high heat that it would take to melt pure tungsten and are not as hard. Tungsten Copper Alloy - Cu + WConsisting of pure tungsten (W) powder suspended in a matrix of copper (Cu), these alloys are readily machinable and known for good thermal and electrical conductivity, low thermal expansion, being non-magnetic, good performance under vacuum, and resistance to erosion from arcing.. Thus, they are often used as electrical contacts, particularly in high voltage applications.

Papers are focused on many aspects of the modern technologies of heat treatment of metallic materials:heat treatment of 3D printed alloys and intermetallic compounds, cryogenic treatment of tool steels and cemented carbides, research of the
Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied (Fig. 8.41).Macroscopic hardness is generally characterized by strong intermolecular bonds, but the behavior of solid materials under force is complex; therefore, there are different measurements of hardness:scratch hardness, indentation hardness, and rebound hardness.
