Strengthening of metals

These metals and their planetary and astrological correspondences are important in many aspects of Witchcraft and Alchemy, ranging from colour, candle, talismanic magic or just observing auras. This is not a complete list, rather it is a general guideline on Metals and their meanings.

Jump to navigation Jump to search Two vises apply tension to a specimen by pulling at it, stretching the specimen until it fractures. The maximum stress it withstands before fracturing is its ultimate tensile strength.

Ultimate tensile strength UTSoften shortened to tensile strength TSultimate strength, or Ftu within equations, [1] [2] [3] is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strengthwhich withstands loads tending to reduce size.

In other words, tensile strength resists tension being pulled apartwhereas compressive strength resists compression being pushed together. Ultimate tensile strength is measured by the maximum stress that a material can withstand while being stretched or pulled before breaking.

In the study of strength of materialstensile strength, compressive strength, and shear strength can be analyzed independently.

Some materials break very sharply, without plastic deformationin what is called a brittle failure. Others, which are more ductileincluding most metals, experience some plastic deformation and possibly necking before fracture.

The UTS is usually found by performing a tensile test and recording the engineering stress versus strain. The highest point of the stress—strain curve see point 1 on the engineering stress—strain diagrams below is the UTS. It is an intensive property ; therefore its value does not depend on the size of the test specimen.

However, it is dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.

Strengthening of metals

Tensile strengths are rarely used in the design of ductile members, but they are important in brittle members.

They are tabulated for common materials such as alloyscomposite materialsceramicsplastics, and wood.

The Metals

Tensile strength can be defined for liquids as well as solids under certain conditions. For example, when a tree [4] draws water from its roots to its upper leaves by transpirationthe column of water is pulled upwards from the top by the cohesion of the water in the xylem, and this force is transmitted down the column by its tensile strength.

Tensile strength is defined as a stress, which is measured as force per unit area. For some non-homogeneous materials or for assembled components it can be reported just as a force or as a force per unit width.MSE Introduction to Materials Science Chapter 7, Strengthening 2 Why metals could be plastically deformed?

Further information. VDM® Alloy is an age-hardenable nickel-chromium-iron alloy. The hardenability is obtained by means of addition of titanium, niobium and aluminum that form strengthening precipitates during heat treatment.

Strengthening of metals

AISI or SAE grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. Forging of this steel should be carried out between and º F ( and º C). This alloy finds many applications for the aerospace and oil and gas industries, along with uses the automotive, agricultural and defense industries.
