the relationship between grain size and strength can be determined by the Hall- Patch relationship of Strength of materials.
In soldering and welding, 2 or more pieces of metal are joined by melting metal at the interface between them. When the molten metal cools and hardens, it physically bonds the pieces together.
they are both metal
photoelectric sensor-sense both metal & non-metal proximity sensor -sense metal only
Solar energy. the electrons are constantly moving between the atoms, giving metal the "shimmer" also why metal is such a good heat conductor.
they are the same metal
The amount of heat required to vaporize the metal is a measure of the strength of the bonds that hold that metal together.
No. The tensile strength comes from the grain inside the metal and the ingredients used to make a certain metal. Lengths are determined by tensile strength and material advised to be used for that specific use.
Against the Grain, if you bend with the grain it will split the grains
Metal Grain Direction is similar to Wood Grain Direction. It is the direction in which the metal was produced, so when you look at it under a magnifying glass and see lines, that is the direction in which the metal was made in the factory.
Heating a metal decreases the tensile strength and increases ductility
Alloys can add strength to a metal
All metals have a tensile strength. The strength varies with the metal and with such factors as temperature and additives.
It doesn't, it depends on how fast the metal was cooled.
The are forged, that is the chosen metal is melted and poured into a mold of the blade shape. The metal is allowed to cool, removed from the mold and the excess metal is removed and recycled. Then there are several inspection procedures that are meant to ensure proper strength, grain alignment, etc.

Grain flow is a typical grain pattern generated during forging of metal. When a piece of metal is cold or hot forged by applying external force or pressure, then metal starts deforming normal to the direction of application of pressure. During the process of permanent deformation, metal grains get deformed & generate what is known as" flow lines ". This is called Grain Flow. It can be seen by chemically etching cross sectional piece of forge metal shown fig below.
