What is aneling?
i think its "annealing"... if so, it is a process where both metal and glass are heated in order for them to change their/its properties.
What causes you to burn a hole in the metal during arc welding?
Either too much amperage, travel speed too slow, or electrode too large for the metal thickness.
What causes a broken or fractured camshaft?
Lack of lubrication or defect in the metal.
What is arc crater?
Arc crater is the depression in the molten metal created by the end of the welding electrode during the welding of metal.
How coring of alloys during solidification be prevented?
By proper composition of metal & by slow cooling & by uniform distribution of metal
What does the term annealing mean?
It's heat treatment. By heating and cooling a metal under very controlled circumstances the properties of the metal can be improved.
What is the meaninig of annealing?
annealing means the process of heating a metal to increase its softness and reduce its brittle nature.
What has the author Andre Burkhardt written?
Andre Burkhardt has written: 'Effects of applied fields during annealing of metal nanoparticles'
What is the scientific term for heating metal and then rapidly cooling?
Annealing is a term used for when metal is heat hardened
Why is annealing done?
Annealing can bring about ductility, soften material and it relieves internal stresses, This will improve the ability to work the metals when they are cold i.e. when bending steel in presses to make metal frames etc
What is the annealing process of metal heat treatment?
The process of heat treatment in which a metal or alloy is heated to an appropriate temperature, held for a certain period of time, and then slowly cooled (usually as the furnace cools) is called annealing.The essence of annealing is to heat steel to austenitizing for pearlite transformation, and the annealed tissue is the nearly balanced one.Purpose of annealing:(1) Reduce the hardness of steel, improve the plasticity, and facilitate machining and cold deformation processing;(2) Uniform steel chemical composition and structure, refine grain, improve steel performance or prepare for quenching structure;(3) Eliminate internal stress and work hardening to prevent deformation and cracking.
What is the annealing temperature for 304 stainless steel?
Annealing. Heat from 1010oC to 1120oC and cool rapidly in air or water. The best corrosion resistance is obtained when the final annealing is above 1070oC and cooling is rapid.
What are the stages of the annealing process?
There are three stages in the annealing process. The first stage is when a metal is heated up and it is called the recovery stage. The second stage is called recrystallization and the third stage is called gain growth. Each stage represents a higher temperature in the annealing process.
Purpose of Heat treatment in carbon steel?
Generally used to improve the properties of the metal. For example to make it tougher or harder. Metals that have been cold worked will have areas of built up stress, which will waken the metal. Heat treatment can be used to remove the weak areas. Which heat treament is used depends on the desired properties of the final metal. Some examples are : Annealing Normalizing Quench Hardening Case hardening

What is the term given to the Sudden cooling of metal during heat treatment process?
quenching
What is intercritical annealing?
Intercritical annealing is where the metal is heated to between its lower and upper critical temperature point to allow partial transformation of the matrix into austenite followed by slow cooling or holding below the lower critical temperature point.
