Higher strength materials usually show lower susceptibility to hydrogen embrittlement

When measuring material flow behavior to model metalworking processes, why is tensile testing not preferred?

Consider two rolled steel plates A and B with the same composition. Plate A has a thickness of 20mm and plate B has a thickness of 5mm. If Charpy samples of identical sizes are tested from both plates, which one of these would likely be true [2 pts] and explain why [3 pts] Plate A has higher transition temperature than plate B Plate A has lower transition temperature than plate B Plate A and B will have identical transition temperatures  

Fill in the blank – [2pts] Hot working occurs when the combination of temperature and deformation rate enable _______________ during deformation

What range of strain rates would you use to test for hydrogen embrittlement? [2pts] Explain why [2pts]

Hot working is typically performed over multiple passes, with the temperature of the final pass known as the finishing temperature. How is finishing temperature chosen? [3pts] How is this choice intended to improve final mechanical properties? [2pts]

Which of these methods can be used to investigate whether temper embrittlement occurred in a material?  

Neutron irradiation has been shown to lower DBTT by as much as 200°C
