During the atomization process, how are molten metal particles broken down into fine powder?
By rapidly cooling the molten metal in a water bath.
By subjecting the molten metal to a strong jet of air or gas.
By grinding solid metal ingots into fine particles.
By melting the metal in a vacuum chamber.
What is the function of the vibrator in the atomization setup for powder formation?
To melt the metal.
To cool the metal particles.
To collect the condensed metal powder.
To spray the molten metal.
Which method of powder formation involves rotating molten metal at high speed, causing droplets to detach and solidify into powder upon contact with cooling air?
Gas atomization
Water atomization
Centrifugal atomization
Mechanical alloying
What is the primary purpose of vibrating the die after filling it with metal powder during the compaction step in powder metallurgy?
To increase the density of the powder.
To remove trapped air from between the powder particles.
To create a smoother surface finish on the final component.
To pre-sinter the powder before heating.
What fundamental process occurs during sintering that transforms compacted metal powder into a solid, cohesive component?
Melting of the entire powder mass.
Chemical reaction between powder particles and the die.
Formation of metallurgical bonds between adjacent powder particles.
Evaporation of impurities from the powder.
What factors primarily determine the specific temperature and duration required for the sintering process in powder metallurgy?
The size and shape of the die.
The type of metal being sintered.
The ambient humidity.
