An illustration of why sloped armour offers no weight benefit when protecting a certain frontal area. Comparing a vertical slab of armour (left) and a section of 45° sloped armour (right), the horizontal distance through the armour (black arrows) is the same, but the normal thickness of the sloped armour (green arrow) is less.
Stellite alloys are a family of completely non-magnetic and corrosion-resistant cobalt alloys of various compositions that have been optimised for different uses. Stellite alloys are suited for cutting tools, an example is Stellite 100, because this alloy is quite hard, maintains a good cutting edge at high temperature, and resists hardening and annealing.
In one study, strain hardening exponent values extracted from tensile data from 58 steel pipes from natural gas pipelines were found to range from 0.08 to 0.25, [1] with the lower end of the range dominated by high-strength low alloy steels and the upper end of the range mostly normalized steels.
Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
The ASTM standard E1820 for the measurement of fracture toughness [11] recommends three coupon types for fracture toughness testing, the single-edge bending coupon [SE(B)], the compact tension coupon [C(T)] and the disk-shaped compact tension coupon [DC(T)]. Each specimen configuration is characterized by three dimensions, namely the crack ...

The conditions necessary for a noticeable edge to build up are that: the cutting speed is low. [2] This is because at high cutting speeds the metal moving away from the workpiece becomes hot enough to recover before seizing onto the tool, preventing the formation of a BUE. [3] the metal being cut is one that work-hardens and is reluctant to ...
Bending of an edge-clamped circular plate under the action of a transverse pressure. The left half of the plate shows the deformed shape, while the right half shows the undeformed shape. This calculation was performed using Ansys .
