Material process such as Rolling and Bending Cause
Plastic deformation
Elastic deformation
Plastic deformation will cause the material strength to
Increase
Decrease
One disadvantage of too much plastic processing of material is
Material will become more brittle
Material will become more Ductile
Material will become more malleable
Material will become more strong
How can we initiate Recrystalization after cold processing of material
By heating the material above a certain limit "Heat Treatment"
By cooling the material very fast "Quinshing"
By adding small amounts of impurities to the metal to create alloy
By adding extra carbon to the outer surface of the material only
How can we avoid Recrystalization after hot working of metals
by heating the material above a certain limit "Heat Treatment"
By cooling the material very fast "Quinshing"
By adding small amounts of impurities to the metal to create alloy
By adding extra carbon to the outer surface of the material only
How alloys are made?
By heating the material above a certain limit "Heat Treatment"
By cooling the material very fast "Quinshing"
By adding small amounts of impurities to the metal
By adding extra carbon to the outer surface of the material only
How is case hardening done?
by heating the material above a certain limit "Heat Treatment"
By cooling the material very fast "Quinshing"
By adding small amounts of impurities to the metal
By adding extra carbon to the outer surface of the material only
How is FCC steel different than BCC Steel?
FCC steel is stronger and can be achieved by alloying with Nickle
BCC steel is stronger and can be achieved by alloying with Nickle
There are no difference between FCC and BCC steel
FCC and BCC are impurities that reduce steel quality
Why does temperature affect the processing of thermoplastics?
Because it will affect the viscosity of the plastic
Because it will affect the Volume of the plastic
Because it will affect the Weight of the plastic
Because it will affect the speed of the plastic
Cross-linkage of chains in thermosetting plastics will
Increase the strength of the plastic
Decrease the strength of the plastic
Its considered as an impurity
It has no effect
Cross-linkage in Thermosetting plastic can be achieved by
High temperature and pressure during polymerisation
Low temperature and pressure during polymerisation
Alloying by adding Carbon to the plastic
Increasing viscosity and density during polymerisation
What is the importance of Reinforcement phase in composite material
Used to add strength to the matrix phase
Used to increase the volume of the matrix phase
Delimitation in composite material is:
Failure of bonding between the matrix and reinforcement phases
Increase of bonding between the matrix and reinforcement phases
A process of adding extra strength to composte material
It is a type of oxidization of steel
