Can someone please help me to solve all the following questions please and thank you!!! Will upvote if all are solved! 1. Explain how Jominy test results can be used to validate aparticular steel grade for a specific application. What is itused for?2. Explain two reasons that powder metallurgy parts wouldhave an advantage over machined parts.3. Explain two main components of cemented carbide and thepurpose of each component.4. Why do we use coatings?5. Name three independent weld parameters and describe howthey affect the final weld quality.6. Explain two advantages brazing would have over boltingcomponents together and two advantages that a bolted jointwould have over brazing.7. Explain why flux is used for shielded metal arc welding(stick welding) and is not used for gas metal arc welding(MIG).8. Discuss two reasons why the heat-affected-zone (HAZ) issignificant in a weld? Explain why pre-heating and post-heating are used.9. Explain how dendritic growth in a hypoeutectic alloy cancause microsegregation. Assume the alloy tometals “A" and “B" and are partially soluble. Includediagrams, as appropriate, and indicate the relativecomposition of the first material to solidify.10. What happens when you lathe a square bar?11. How to find hardness on a Jominy graph.12. Explain the importance of wettability and capillary actionwhen brazing. Name a parameter that effects each of these.13. Explain the importance of each of the following featuresof a flask used in sand casting:a. Filtersb. Wellsmade fromc. Gatesd. Risers14. Explain why both aluminum and titanium have goodcorrosion resistance.15. Explain what the T6 designation means in 6061-T6.Describe the heat treatment that would achieve this.16.

Accepted Answer

Jominy test is used to measure the hardenability of the steel.

1. Explain how Jominy test results can be used to validate a particular steel grade for a specific application. What is it used for?
