Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium, chosen for its excellent conductivity, low weight and low cost. The center strand, or strands is/are of steel for additional strength to help support the weight of the conductor. Steel is higher strength than aluminium which allows for increased mechanical tension to be applied on the conductor. Steel also has lower elastic and inelastic deformation (p ....etc

Composites of shape memory alloys (SMA) with a matrix have been widely studied to suppress the propagation of damage. In these studies, the SMA is used as an actuator. A multi-functional SMA as both sensor and actuator is suitable for constructing intelligent material, such as a material with a sensing and suppressing function. The damage of materials is related to the amount of strain. We studied the use of SMA wire parts as sensors to measure the amount of strain for damage estimation. The acoustic emission (AE) signals induced by phase trans ....etc

SHAPE MEMORY ALLOYS
1. INTRODUCTION
A shape memory alloy (SMA) (also known as memory metal or smart wire) is a metal that remembers its geometry. After a sample of SMA has been deformed from its original conformation, it regains its original geometry by itself during heating (one-way effect) or, at higher ambient temperatures, simply during unloading (pseudo-elasticity or superelasticity). These extraordinary properties are due to a temperature-dependent martensitic phase transformation from a low-symmetry to a highly s ....etc

They re practically twins. Some might say this about superalloys and titanium, but as with most twins, there are a few subtle differences.

Materials like nickel-base, chrome-base, and iron-base superalloys are extremely heat resistant, even more than titanium, so most of the heat produced during machining is absorbed by the cutting edge.

This can wreak havoc on the cutting tool and cause damage ranging from crater wear, to plastic deformation, to complete tool failure.

Most superalloys are not flammable, so they can be machined with ceramic ....etc

SHAPE MEMORY ALLOYS

INTRODUCTION
Shape memory alloys are the alloys which exhibit shape memory effect
If such alloys are plastically deformed at one temperature, they will completely recover their shape on being raised to a higher temperature
INTRODUCTION
In recovering their shape alloys can produce a displacement or force (or both in some cases) as a function of temperature
We can make metals change shape, change position, expand, compress with heat as the only activator
Because of these propert ....etc

Novel shape memory effect (SME) and pseudoelastic behavior are discovered in single-crystalline Au, Cu, and Ni nanowires with lateral dimensions of 1.5-10 nm. Under tensile loading and unloading, these wires can recover elongations of up to 50%, well beyond the recoverable strains of 5-8% typical for most bulk shape memory alloys (SMAs). Results of atomistic simulations and evidences from experiments show that this phenomenon only exists at the nanometer scale and is associated with a reversible crystallographic lattice reorientation driven byt ....etc
